: Lloyd, I mostly am after trying to understand what is happening, right now. I have a luxury of having plenty of time, due to having less food at home that fits onto one fridge. yep. I have repaired a number of them with the same symptom, but the symptom can be caused by more than one problem. As someone else said, a _thoroughly_ frozen-up evaporator can cause the symptom, because the liquid refrigerant won't boil out of the coil fast enough to reduce the head pressure before the next cycle is requested. That's one. A lot of compressors now come with PTC thermistors in place of the potential relays they used to employ to switch the start cap out of circuit. They tend to fail rather easily in a high-humidity environment. Although they're not terribly expensive, I replace all of them with potential relays; sometimes scavanged from other similar-sized compressors, sometimes new. Then, of course, it's possible the new start cap is failing. The compressor could be on the way out. If the bearings are getting sticky or tight, the compressor will be harder to start than it should be. This eventually manifests itself as a "locked rotor", and nothing you can do (effectively) will fix that, except replacing the compressor. Foreign material in the closed system can cause it, too. You didn't say anything about ever opening it, but flakes of insulation from the compressor windings and corrosion flaking off the inside of improperly cleaned or improperly brazed lines can all do it. These, too, are generally fatal problems, and cannot be fixed merely by replacing the compressor and re-charging. LLoyd |

The compressor unit in it would keep trying to start and would be unable to start, tripping an overload relay. After some "time off" to let the system cool, the fridge started just fine. I also replaced a capacitor and relay (which was very cheap and possibly not needed) and thought that I was done. However, since yesterday it started having trouble again. Letting it cool down for a couple of hours would get it started, only to find it unable to restart a few hours later. What could be the culprit here? Unlike last time, there is no emergency, as we have less food and all our food easily fits in another fridge. The refrigerator is a Kenmore made by Amana with fancy electronic front control. i Just guessing, again, but this sounds like the pressure is not bleeding off, for whatever reason. It's hard to imagine seals that would hold pressure for hours, but I suppose it's possible. Or, maybe there's some contamination somewhere - water, perhaps, that's freezing in a low spot in a line? Wait a minute - I just reread your post - Am I right that it does restart if you let it sit a couple of hours? What if you let it sit a few (maybe 5) minutes? Wait till the compressor is running, then unplug it after a couple of minutes. Then wait five minutes and plug it back in. Does it restart then? If so, there's something wrong with the control circuitry. It should not, under normal circumstances, be trying to start against a load. There should be enough hysterisis in the thermostat, or some sort of lock-out timer to prevent rapid cycling. Do you maybe have an air leak - lik in the door gasket? I could see how that would cause rapid cycling. RS I mentioned a month ago the dumb**** probably had ice build up inside the cap tube or possibly if equipped the TEV. You might ask where the moisture comes from in a sealed system. Not knowing the service history of this unit I could not tell you if it actually has ice build up or if the system had been worked on prior to dumb**** purchasing it used. But it sure displays the proper symptoms to be a distinct possibility. |

: Does that refrigeration knowledge amount to so little? Well, HIS does. The body of knowlege a competent tech has is quite large, and encompasses a wide variety of disciplines. You have many of them already. But the skills specific to refrigeration repair are not many, and your learning them wouldn't be a stretch, at all. Now, I said, "technician". There's a whopping difference between a competent tech and a real refrigeration expert. He's the guy who can compute actual superheats based upon the refrigerant's characteristics, the compressor specs, the load, etc. He can do and knows a lot more than that. If you're working on massive chillers for domed stadiums, you need that sort of knowlege. Those guys are real engineers. The techs could do everything they do from a ten page cheat-sheet. And no... I'm not kidding. Like most repair trades, except for the handling and diagnosing of actual refrigeration problems, they solve most of their problems by parts-swapping. Most of their refrigeration-based problems are handled by rote, not by a clear understanding of how the system actually does what it does, or why the pressures must be what they must be, or what actually causes them to go "off". I worked strictly as a grunt for an HVAC guy for a summer, many years ago. With only that training, which consisted mostly of peering over the shoulder of my boss, I got to where I can (and do) repair all of my own R-22 and R-134a appliances. I cannot work on systems using azeotropes, because I can't buy them, and don't intend to get licensed; so I can't fix any R410a problems that require refrigerant. I also cannot buy R-22, but I don't need it (dried and filtered propane works fine, if you don't have R22), and R134a is still available without an EPA certificate and a licensed "master" operator supervising you. Unlike the "pros", I don't deliberately vent systems to the air. I built a small reclamation unit. It saves me the guilt of doing what I see professionals do almost every time I hire one. It also captures some refrigerant, which, if it's not been exposed to a compressor burn-out (and thus containing acid), can be filtered, dried, and returned to service. (and yes, safely. The "pros" would have you believe that _any_ reclaimed refrigerant will instantly destroy anything you put it in) Everything I've needed to know to stay "current" on what I can legally do is available on-line. I don't repair anyone's equipment but my own. I will, however, diagnose friends' systems for them, so they don't get bilked by the repair tech when he finally shows up. LLoyd |

I know a lot of guys who do a great job on HVAC equipment who have trouble working on itty bitty refrigeration units. I prefer the big stuff myself like 60 to 4k tons, it's easier to work on. 8-) TDD |

Its a freakin Kenmore.... call Sears and have a guy come out and fix it, or you can quit screwing around and buy a new one. His time isn't worth anything. He'd rather be the first person on the block with a fridge that cost him five grand than pay $200 for labor. That could be true. I once made a homemade control for a welding machine. It was MIG, stick and plasma capable and welded pretty good (though it was not as convenient to use as an industrial welder like Miller). Anyway, when I calculated the amount of little parts, doodads, and my time at a VERY conservative rate, the time investment in the welder control was so enormous that at something like $20 per hour, I could have used this time to buy the nicest brand new Miller welder out there. But the difference between making that weld control, versus fixing the fridge, is that when I was asking about various specifics, I got educational, useful answers, instead of screaming and howling like I get from some (but not all) losers that seem to hail from alt.hvac. I, obviously, always welcome any useful ideas that would come from constructively minded HVACers. i |

You need more than a fiddle to perform refrigeration repair. Yes, so I am trying to learn some more specifics. Some people were helpful and to them, I am grateful. I the last time I had those symptoms, it was a 1947 Norge that had run until 1987. I took it apart, and the root cause was lack of lubrication to the rod bearing caused by a particle of some kind getting into the lubrication hole and blocking it - Still, one can't be too unhappy about a 40 year life on a refrig. I replaced it with a same brand unit, which didn't make 1 week before requiring 2 (warranty) service calls. When it got replaced in about 10 years, I took it outside and it drained water out of the insulation for several days - there were gallons of water frozen in the lining - the old norge had none of that. Replacement refrig seems ok so far. |

LLoyd I usually only see those for AC units where a burnout is often much more spectacular. I haven't paid attention to the small bullet dryer specs to look for acid neutralizing media content. Acid Away is a liquid that mixes with the refrigeration oil. I use the liquid in addition to the Sporlan HH series dryers on an AC burnout. If the AC evaporator and line set is badly contaminated, I use a cleaner blown through it with nitrogen too. In my opinion, the Acid Away protects the compressor much better than a dryer alone because it stays in the oil in every part of the system like the windings of the compressor motor that are vulnerable to being damaged by acid. There are those critters out there who will just throw a system in and head down the road without regard for how long it will last the customer. TDD |

I became interested in homebrewing, and am about ready to kick it off. I DO need a dedicated refrigerator, though. I managed to get six Cornelius kegs with connectors and a regulator for $100. I may get God knows what more, as I am swapping with a guy who wants my 1200 gal. water tank, and he works for Coke/Dr. Pepper and I am pretty sure he is getting this stuff for free. I am negotiating getting all the "stuff" from a home brewer who was SWMBO'd, except for a $12 wort cooler, which I can build cheaply, and all for $125. Weather here is hot, and SWMBO will surely complain of the odor of the flatulent fermentation process, so I guess I'll have to retire to the containers and make a dedicated beer brewing area, complete with hot water, triple tank NSF sink, dedicated refrigerators, and welded racking systems to make things easier. Moving along right on the time line. Should be an interesting and fun hobby. With the state of the economy today, "working fridges", particularly the top/bottom varieties can be had for a song, and sometimes for just picking them up. When I was about 18 (1966), I found an old refrigerator in a motel they were tearing down. It had the freezer part on top, but only one door. Wish I knew the brand name, but for the time, was top of the line. Probably go for a grand on ebay today. I brought it home, covered it in zebra terrycloth, and put it out by the pool for a beer and soft drink fridge. It was running when I sold the house, and had probably been running at least twenty years prior. They don't make stuff like they used to. Steve Heart surgery pending? Read up and prepare.

Refrigerator repairmen to me are like teachers. They can't make it in the
real world, or at any chosen discipline, so they just take the easy way out, and settle for a position that at least doesn't have a social stigma like "gutter cleaner". If they were able to grasp the basics of HVAC, they'd be out there changing 10 ton units, doing new construction, putting in very large walk in coolers or freezers, or the like. But instead, they don't have what it it takes to make it in the trade, so they fall back on "refrigerator repairman." Which to me is the same to "bicycle mechanic."

The body of knowlege a competent tech has is quite large, and encompasses a wide variety of disciplines. You have many of them already. But the skills specific to refrigeration repair are not many, and your learning them wouldn't be a stretch, at all. Now, I said, "technician". There's a whopping difference between a competent tech and a real refrigeration expert. He's the guy who can compute actual superheats based upon the refrigerant's characteristics, the compressor specs, the load, etc. He can do and knows a lot more than that. If you're working on massive chillers for domed stadiums, you need that sort of knowlege. Those guys are real engineers. The techs could do everything they do from a ten page cheat-sheet. And no... I'm not kidding. Like most repair trades, except for the handling and diagnosing of actual refrigeration problems, they solve most of their problems by parts-swapping. Most of their refrigeration-based problems are handled by rote, not by a clear understanding of how the system actually does what it does, or why the pressures must be what they must be, or what actually causes them to go "off". I worked strictly as a grunt for an HVAC guy for a summer, many years ago. With only that training, which consisted mostly of peering over the shoulder of my boss, I got to where I can (and do) repair all of my own R-22 and R-134a appliances. I cannot work on systems using azeotropes, because I can't buy them, and don't intend to get licensed; so I can't fix any R410a problems that require refrigerant. I also cannot buy R-22, but I don't need it (dried and filtered propane works fine, if you don't have R22), and R134a is still available without an EPA certificate and a licensed "master" operator supervising you. Unlike the "pros", I don't deliberately vent systems to the air. I built a small reclamation unit. It saves me the guilt of doing what I see professionals do almost every time I hire one. It also captures some refrigerant, which, if it's not been exposed to a compressor burn-out (and thus containing acid), can be filtered, dried, and returned to service. (and yes, safely. The "pros" would have you believe that _any_ reclaimed refrigerant will instantly destroy anything you put it in) Everything I've needed to know to stay "current" on what I can legally do is available on-line. I don't repair anyone's equipment but my own. I will, however, diagnose friends' systems for them, so they don't get bilked by the repair tech when he finally shows up. LLoyd What % of the time would you estimate that happens? Steve |

I cannot believe that, after fixing and retrofitting my Bridgeport Interact CNC mill, I cannot ever properly diagnose a bad Sears refrigerator. I started knowing nothing about CNC mills and now, thanks to all the great help I got, I have a working CNC machine. Maybe I can fix the fridge too. i I don't see why not, I remember fixing a CNC machine that had a Toshiba bubble memory unit in the controller. It was a hoot, when I told the kid at the electronic supply house about the bubble memory unit, I got a blank stare and a "duh?". Remember all the hype about Bubble memory? It was supposed to do to solid state RAM, what RAM did to core memory. I've only seen one computer with Bubble memory, and it failed twice in two years. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |

At least a couple times in my life. I've worked on systems that the
customer insisted were low freon, but turned out to be other problems. One restaurant. The upright two door freezer had some kind of compressor problem. Two cylinder compressor, about half the amps. The owner totally insisted that it needed freon. Out back, are the compressors for the cases indoors. The one for the pie case, I think it was 1/3 HP compressor, with a receiver. The walk in cooler was 1/2 HP, if memory serves. I put my gages on, and checked amp draw. I could tell by the sound, the units were really straining. The head was waay, waaay, up there. I tried to explain (the old guy was very deaf) the actual problem. He insisted the one needed 5 pounds of freon, the other needed 8. I got out my Johnstone catalog, showed him the receiver holds 1.5 pounds or was it 1.7 (been about three or four years ago). I told him that I'd need to fix the actual problem. He refused to let me fix the problem. Insisted that I add 5 pounds to the one system and 8 pounds to the other. I finally walked off. I hope he leaves the business some day and his wife calls me back. She was a lot more pleasant. Perhaps he can retire to Florida, and enjoy his retirement there. Of course, depending which tech you called. You might get a couple pounds of freon added to your system, or you might get a proper repair. -- Christopher A.
