Problem with clothes dryer not getting hot enough: How do you test a sensor?
Got a problem with a clothes dryer not working. It leaves clothes wetter when it is finished than when it started! That is because it doesnt seem to get hot enough and a certain amount of water feeds into the drum in the normal course of drying.
There is a sensor which I assume tells the element how hot to get and the element itself. The sensor usually dies in this machine and I Have had to replace a few of them. I check the wires and when they start to look burned, a replacement sensor is needed. When I get the sensor out, one terminal usually looks completely burned. However in the present case, I ordered a new sensor and then found that the one in there LOOKS perfectly OK. The wires look burned but that seems to be because they burned on some last replacement occasion. When I pulled the actual wires off, the terminals look OK and the sensor looks OK. How can I check the sensor to see if it is really OK or whether the sensor has now failed in some other way? Alternatively how can I check the terminals of the element itself to see if it that part which needs replacement? |

First, there's no way a dryer leaves clothes wetter than when they started unless you have a water source feeding into the dryer. You said "...and a certain amount of water feeds into the drum in the normal course of drying." Really? From where? That said, very often the type of problem you described is caused by a blockage in the exhaust ducts, either internal to the dryer or the exhaust hose and/or vent. Cleaning the lint trip every time is a great idea, but it doesn't prevent lint from building up in other places. I would check the outside vent for buildup and the exhaust hose itself. If that doesn't help, you'll have to get to the innards and clean out the ductwork within the dryer itself. BTDT...Often. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Thanks for the suggestion but we live in a small apartment and needed a ductless dryer. It doesn't vent to the outside and besides the water outlet (I have checked that one), there aren't any filters to clean out.
I never understood why it meeds to feed water into the dryer while it is drying but it does. There is a water input for that purpose. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Yes, it is a w/d combination unit but the washer bit works properly. The point is that in a past repair, the manufacturer replaced the wiring but for some reason kept the plastic casing around the connectors which look burned.
I thought that the sensor had gone and spent a large amount of money on a new sensor before discovering this. When I came to replace it, I discovered that the sensor in the unit LOOKS new. So now i am wondering whether it is sending the wrong message to the heater element or whether it is the heater element which has gone bad. So I was wondering how to test each (or whether something else is bad on this unit) |

There are two things you should check right away:
1. The problem could be that the high temperature thermostat is gone. Dryers have TWO thermostats; a 165 deg. F (typically) thermostat that's used for both the "Whites & Colours" and "Permanent Press" dry cycles and a 145 deg. F (typically) thermostat that's only used for the "Delicates" dry cycle. Try running the dryer on the Delicates dry cycle and see if it gets quite warm, or at least warm enough to dry clothes. If so, then the problem is a shot high temperature thermostat, and you need to replace it. 2. Electric dryers are 240 volt appliances... ...which means they will have TWO 30 amp fuses or circuit breakers in the electrical panel providing power to the dryer. Check that both fuses or circuit breakers are good/not tripped. If one fuse burns out or one breaker trips, the dryer motor can still run properly (because it works on 120 volts) and the heating element will get warm to the touch, but not red hot, and it needs to be red hot to heat the air being drawn through the dryer by the blower up to 145 or 165 degrees. If the fuses or circuit breakers haven't blown/tripped and the dryer doesn't heat on either thermostat, then I'd suspect the heating element. Some dryers have a high limit safety switch that needs to be replaced if the dryer overheats. In that case, you need to find the reason why the dryer overheated and fix that problem, and then also replace the high limit safety switch. Last edited by nestork : March 22nd 13 at 02:43 AM |

Yes, I can close the water input valve but the unit then wont start. Tried the site you mentioned but it doesnt list any of the names this unit goes under: Euro-Pro, M alber, etc. I think it was probably made by Indesit but dont think there is an Indesit model number! The unit looks like a gigantic number of other units by lots of manufacturers but I suspect that one company makes the external casings for all these machines in Italy and sells them on, So you cant easily identify it. That was wny I was trying to look at how to test components. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Actually I am not really sure how useful that site actually is
I did find a reference to this question being asked about an earlier model about seven years ago. It then waited two years for someone else to answer with a report of a similar problem. No solutions despite this unit being in widespread use on both sides of the Atlantic in various forms. I could have told them to check the wires going to the sensor myself!! It would probably have fixed one of the two problem reports or both of them. And the manufacturer lists it as a commonly replaced part (along with the element, (big surprise) |

About a number of things. Checking Google doesn't reveal the profile of a typical troll: http://www.google.com/search?q=Amanda+Ripanykhazova The added water could indeed be a failure of a combination washer/dryer unit, as one of the posters you've labeled a "fool" correctly deduced. So tell us, what leads you to believe you've been trolled? At least, if this IS a troll, it's on topic, unlike so many other trolls here, and could help someone in the future as well as the person asking the question. For a *real* troll, check out the doghouse thread or most anything posted by Dufas, the "entertainment troll" or Harry, the Brit that hates America. -- Bobby G. |

Yes, I can close the water input valve but the unit then wont start. That's interesting. A combined washer/dryer unit won't do a dry cycle without water? That's one of the big drawbacks to these combined units. More complex, easier for one little thing to screw up the whole works. I think Retired's idea that water may be leaking in is an interesting one, IF it's really true that the clothes are coming out wetter than when they went in. Water being added is the only way that's possible. On the other hand, if that's what's happening due to a leaking valve, then one would think it would continue with the unit off and flood the place. I guess it's possible something is screwed up that tells the valve to open at times when the unit is active. How about if the water is turned on when it's started and then turned off once it starts drying? Maybe it checks for water at startup and doesn't care after.... |

"Retired," that's an excellent idea for a test to determine if there's a leak within the system. By the OP's description this problem is not like previous problems because the sensor does not appear to be burned as it has in the past. The OP can test the sensor if she has a thermometer and a meter that can test for continuity. The sensor is designed to cut out (stops passing electrical current) when a certain temperature, usually stamped on the part itself, is exceeded. If this unit has failed in the "open" state then the dryer's heating element will never kick in. Another sensor prone to problems is the humidity sensor. That's a little harder to test. You can try placing completely dry clothes in the dryer and then turning on the dryer. If the sensor is OK it should run for a few moments and then shut down right away. I'd try "Retired's" suggestion of shutting off the water supply to make sure that there's no leak that wetting the clothes as the dryer is trying to dry them. If you think the heating element has failed, you can bypass the thermostatic control sensor with a small jumper cable and run the dryer for a few minutes. If it fails to heat up at all, a bad heating element could be a distinct possibility. You can bypass the humidstat the same way. Remember to remove the jumper when you've finished the test so you don't burn the house down! -- Bobby G. |

Did you check Google before you made your troll accusation? http://www.google.com/search?q=Amanda+Ripanykhazova You appear to have gone straight to "troll accusation mode" without *you* plugging in and ended up calling some of your fellow newsgroupers fools because they tried to help someone. I've already learned something new just from reading the on-topic thread, no matter how it started so there's already been value added in the thread. I always welcome the chance to see what diagnostic skills other posters have with topics I know about so I know whether to trust them with topics I am not familiar with. Several people have made some very good observations about potential problems, so even if the OP was a troll, there's good information being exchanged and archived. With all the race-baiting political trolling and sock puppetry that goes on here, you sure picked an odd and on-topic post to get worked up enough to call other people fools who erred on the side of helpfulness and tried to help someone you labeled a troll. Sheesh. What a welcome. Using a female name can prompt them to spend a week on the line trying to coax free the pertinent information, and another week after someone points out they've been trolled, again. "Them?" Who do you mean by "them?" What you did: not checking Google before shouting "Troll!" is almost exactly what you accused others of doing (going straight to diagnostic mode) but worse. The people who tried to answer the question added value to the world and the Google archive. What value did YOU add? Just some name-calling and a dash of "Look at me, I am smarter than them!" Double sheesh. Would you give me 10 cents for every legitimate post for help that didn't immediately include a make and model number? After all, that seems to be the measure you use to judge if someone's a troll. That and if the poster's female. Triple sheesh. I hope Norminn's reading this. Remind me who the troll is again?

If so, then the problem is a shot high temperature thermostat, and you need to replace it. It would be nice to be able to determine how much current the unit is drawing. Not sure how to do that short of isolating a service wire and using a tong meter. I've not seen a Kill-o-watt meter that runs on 240VAC. If the washing machine component is leaking into the dryer, even if the heating element activates, there won't be much drying getting done. It may be possible to detect a slight rise in temperature, though. Still, I'd probably want to test the unit watching an ammeter to see if the element was indeed cycling on and off. Sometimes the problem can be short-cycling where the heating element is being activated, but for some reason is not reaching operating temperature. There is probably another thermal shutoff device located right on the heater element assembly that may have failed but I've never serviced a combo unit and this may be foreign made, as well, so who knows? 2. Electric dryers are 240 volt appliances... ..which means they will have TWO 30 amp fuses or circuit breakers in the electrical panel providing power to the dryer.

Good point. Put that under yet another reason why the element may not be getting hot enough. If the fuses or circuit breakers haven't blown/tripped and the dryer doesn't heat on either thermostat, then I'd suspect the heating element. Some dryers have a high limit safety switch that needs to be replaced if the dryer overheats. In that case, you need to find the reason why the dryer overheated and fix that problem, and then also replace the high limit safety switch. DerbyDad zeroed in on the number one cause of heating element trouble in my experience - lint. I would start with a thorough blowout/cleanout of the unit and the dryer vent before even looking at other issues. Last time this happened to a friend (wet clothes) the dryer vent had become home to a bunch of birds - house wrens, IIRC. I was amazed at how much nesting material they had brought into the vent pipe. This happened even with a bird flap on the exterior vent. They learned how to pop it open in very short order and it probably helped keep them safe by keeping larger predators out. The symptom of that fiasco was that the dryer vent pipe starting dripping condensate inside the house at the point of the bird blockage. Oddly enough, the water traveled quite a distance from the leak point along the ceiling tiles and it didn't appear until a number of hours after the dryer was used. -- Bobby G. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Thanks for that last paragraph Bobby, that was what I was looking for. I will try it.
Curiously, next to the sensor which is a long pointed device that extends into the vent shaft, there IS another flat round electrical device which looks like some kind of secondary sensor and which also has burned wires (or wire covers!) going to it. But that isnt a commonly replaceable part. I will have to check the spade terminals on that now. How come no one believes that with this unit, even though there doesn't appear to be any sensor to tell when clothes are dry, a small amount of water feeds into the unit while drying to help prevent wrinkling etc? If that water doesn't evap with the heat and get pumped away, you would expect clothes to come out wetter than they went in? To me it seems obvious that it is the sensor or the element? But that is without applying any lateral thinking, which is why I came here. (even if I have to accept that there will be a certain amount of trolling coming from certain elements like VinnyB & GPSMan) More likely is the pump in this condenser unit: Not a whole lot evaps like in a normal vented dryer, everything is pumped out. I wonder if there is a chance that the pump isn't working or isn't working properly. Unfortunately I cant easily disconnect the drain so see what is being pumped out during the dry cycle. |

The reason people are having a hard time believing it is because most of them have never seen a dryer that uses water. This is indeed a feature of some modern high-end dryers, where steam is used for that. The idea is as you say to take wrinkles out. Now, I would think that would only happen if you select a special steam cycle. But some googling shows that apparently these dryers may introduce steam at some point in the drying cycle for wet clothes too. If that water doesn't evap with the heat and get pumped away, you would expect clothes to come out wetter than they went in? Yes, with this type of dryer if the water doesn't turn to steam because the heat doesn't work, then I could see that happening. To me it seems obvious *that it is the sensor or the element? But that is without applying any lateral thinking, which is why I came here. (even if I have to accept that there will be a certain amount of trolling coming from certain elements like VinnyB & GPSMan) It could be a sensor, the element, the wiring, a control board, relay, etc.... The way I fix things like that is to get a circuit diagram. There is usually one of those in the unit itself, typically pasted on the back or maybe on the back of one of the main access panels, or sometimes just a folded up sheet stuck inside behind a panel. With that and a test meter I trace out the circuit to try to determine what is not working and why. More likely is the pump in this condenser unit: Not a whole lot evaps like in a normal vented dryer, everything is pumped out. I wonder if there is a chance that the pump isn't working or isn't working properly. Unfortunately I cant easily disconnect the drain so see what is being pumped out during the dry cycle. I have no idea how that part of the dryer works, never seen one. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Look, I don't know how a condenser unit works but am reasonably sure it doesn't work strictly by evaporation. The evap'ing going on is just a precursor to pumping the evaporated water out. There is no (lint) trap to clean out..
http://malberappliance.com/WD1000Par...gsCombined.pdf Similarly, there is no fuse to check IN this machine. And there are only two drying cycles, one a heated one and the other (I never figured out what it is for and have never used it) a non-heated one which just tumbles. I assume this is for a minuscule amount of exceptionally delicate pieces. But I will go back and try it to see if there is ANY heating going on at all in that cycle as your suggestion is a good one in theory |

It leaves clothes wetter when it is finished than when it started! That is because it doesnt seem to get hot enough and a certain amount of water feeds into the drum in the normal course of drying. At first I thought this was a pretty lame troll; that no one would be fool enough to fall for it. But then I see that several fools here did indeed go for it; so I guess I was wrong. About a number of things. Checking Google doesn't reveal the profile of a typical troll: http://www.google.com/search?q=Amanda+Ripanykhazova The added water could indeed be a failure of a combination washer/dryer unit, as one of the posters you've labeled a "fool" correctly deduced. So tell us, what leads you to believe you've been trolled? At least, if this IS a troll, it's on topic, unlike so many other trolls here, and could help someone in the future as well as the person asking the question. For a *real* troll, check out the doghouse thread or most anything posted by Dufas, the "entertainment troll" or Harry, the Brit that hates America. -- Booby G.

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
Actually I do kinda need a wiring diagram or at least some interpretation.
There is a mystery grey wire which comes out of the wiring loom and heads generally towards the rear terminal of that secondary sensor. As far as I can see, it goes into the loom, going towards the rear of the unit. A grey wire does emerge from the rear of the loom and connects to one terminal of the dryer fan. The sensor itself has clean terminals and the spade connectors are clean and show no signs of arcing. But I wonder whether that grey wire does in fact go to that rear terminal along with the wire which is already connected to it? The wires coming off the spades do look a bit burned and frayed so I suppose the gray wire could come off it. THe manufacturer's agent was clueless as to what this wire is and whether it IS supposed to go somewhere. There are two other mystery wires, both orange. One comes from the front panel and ends in a spade terminal which isnt connected to anything. There is also another orange wire (emerging from the loom) which also appears clipped off and doesnt look as if it was ever connected to anything |

How come no one believes that with this unit, even though there doesn't appear to be any sensor to tell when clothes are dry, *a small amount of water feeds into the unit while drying to help prevent wrinkling etc? The reason people are having a hard time believing it is because most of them have never seen a dryer that uses water. * This is indeed a feature of some modern high-end dryers, where steam is used for that. The idea is as you say to take wrinkles out. *Now, I would think that would only happen if you select a special steam cycle. *But some googling shows that apparently these dryers may introduce steam at some point in the drying cycle for wet clothes too. If that water doesn't evap with the heat and get pumped away, you would expect clothes to come out wetter than they went in? Yes, with this type of dryer if the water doesn't turn to steam because the heat doesn't work, then I could see that happening. To me it seems obvious *that it is the sensor or the element? But that is without applying any lateral thinking, which is why I came here. (even if I have to accept that there will be a certain amount of trolling coming from certain elements like VinnyB & GPSMan) It could be a sensor, the element, the wiring, a control board, relay, etc.... * *The way I fix things like that is to get a circuit diagram. *There is usually one of those in the unit itself, typically pasted on the back or maybe on the back of one of the main access panels, or sometimes just a folded up sheet stuck inside behind a panel. *With that and a test meter I trace out the circuit to try to determine what is not working and why. More likely is the pump in this condenser unit: Not a whole lot evaps like in a normal vented dryer, everything is pumped out. I wonder if there is a chance that the pump isn't working or isn't working properly. Unfortunately I cant easily disconnect the drain so see what is being pumped out during the dry cycle. I have no idea how that part of the dryer works, never seen one. The OP is not a troll.... he just has a machine that most of us are unfamilair with. http://malberappliance.com/wd2000usermanual.pdf As mentioned & discussed in a number of followup posts, this is a combo machine; it washes & dries in the same tub! I had the misfortune for having to used a machine of this type nearly 10 years ago in New Zealand. It took over 3 HOURS to do a pair of jeans, some socks & rugby jersey and they still came out damp. IME these type of machine suck...even when they're working. I can imagine they're some sort of "green thinking" run amok. But they probably do save a lot of energy... washing & drying take so long, one decides to do fewer loads. Take a look at the manual... cycle times are shown on page 11. Read the Troubleshooting section...pages 16 & 17 There is a note on page 11 about load size during drying... the dry times range from 2 to 2.5 hours! On pages 16 & 17 is gives "tips" to improve drying performance. There is also a note that total cycle times could be as long as 4 HOURS! It also reveals the tidbit that drying load capacity is 1/2 of the washing load capacity! WTF? Question.. I often see washer capacity noted in 'lbs' . I this manual it talks about 11 lbs, I see US washer rated at 20 lbs. Are the these the weight of the dry clothes? I've also seen washers rated by cubic feet. What's the deal? Clearly the OP's combo machine is "Suzie Homemaker" sized, cabinet is only 23-1/2" wide. All in all....imo, this type of machine is a total POS. I seriously doubt that they save any energy in the long run, since they expose clothes to excessively long dry cycles and the attendant abrasive wear. I think the problem with this thread.... a number of people think it's trolling & a number of people are applying "US style dryer" diagnosis to it. When in reality, it's a "real" machine & its performance sucks. Link to explanation of condensing dryer... I didn't vet this info for 100% accuracy but it seems like a dehumidifier for clothes. cheers Bob |

What I need now isnt to read/ignore all the trolls here, but to use your & Optonline's diagnostics on the parts and/or try to figure out whether that mystery grey wire floating around which may connect the secondary sensor to the fan is the problem. |

We don't even know what kind of "sensor" it is. Can you get the sensor out easily? Does it have a part # on it? If so, you could try googling for the sensor part # and maybe you'll find some discussion somewhere about what kind of sensor it is, how it works, how to test it, etc. As I said before, my approach with this kind of thing is to try to figure out the operational principles of the machine, ie what has to happen for voltage to go to whatever heats it and then figure out what is preventing it. Otherwise you're just going to start replacing parts without knowing if it's really bad or not. That approach works for a lot of repairmen that have an inventory of parts to swap. But for us, it can get expensive. |

Problem with clothes dryer not getting hot enough: How do youtest a sensor?
this does appear to be a type of dryer that is "new" to many of us
http://ths.gardenweb.com/faq/lists/l...958010854.html yes it is essentially a de-humidifer for clothes. so if it is a condensing dryer, and the so called outer loop is a water loop, then what the OP said starts to make sense. The machine won't run without a water supply because it uses the water flow to cool the condenser ? So if the machine has a refrigeration cycle similar to a DE-humidifer, and the refrigeration section is not working, there is a whole list of things that could possibly be wrong... OP, when the machine was working in the past, did it make a humming sound like an air conditioner? Does it still make that sound now? Mark |

ok, most of these are NOT refrigeration based...
but this paragraph is relevant to the Op With most current standalone condenser dryers, it is necessary to periodically clean the condenser unit - perhaps once a month or so, one needs to slide out the condenser module and wash off any accumulated lint. Thus condensers require a bit more "work" than vented dryers - although this may entail less actual effort than the recommended annual ductwork cleaning for vented dryers (which is very important for both performance and fire safety reasons!).

It's common for manufacturers to tape a folded up wiring diagrahm and schematic inside appliances. This keeps the service guys from having to haul around hundreds of them. You have a combination washer, condensing dryer. It does not add water to the clothes during the drying cycle but may use water to cool the condensing unit. They are not usually very good at drying but make up for it some by having a really high spin cycle at the end of the wash phase. And if you do not have a outside vent there's not much you can do I don't know your specific model but generally there are several temp sensors on the drying cycle as well as possibly a moisture sensor. The temp sensors may include ones to prevent it from going over a certain temp while running as well as a safety sensor that has a higher temp. Often the safety one is a one-shot, once it has been tripped it must be replaced. That's on the theory that some other failure caused it to be tripped and the appliance needs other work as well as a new safety temp sensor. Finding the schematic is going to be very helpful. Some google searches might help you as many manufacturers also make theoir schematics available online. These are also not super complicated so it is possible to trace the heating circuit out by hand. And a volt ohm meter would help a lot with this and with trouble shooting in general. As a general rule the temp sensors will be closed when cool if they are wired in series with the heating element.. If they are connected to a main control board they may be open when cool and closed when hot. You can check these with a hair dryer. You can also check for continuity of the heating element. If you can get enough covers off to get to the heating element but still be able to run the unit you can also check for voltage at the heating element while it is running. |
