R-22 Heat Pump update
I was able to get a cylinder of R-22 and the right manifold and hoses
and finally it was good enough weather to check out the system. Not good! First, the fan on the condenser wouldn't start on it's own but a little push with a screwdriver got it spinning. The bearings seem OK so I suspect the capacitor. Next, the compressor won't start, it just hums for a while then goes quiet then repeats. Hmmmm. The static pressure on the refrigerant is 110 psi on both sides at 70 degrees F ambient. So, I assume the worst on this 15 yo Trane and it won't be worth fixing. At this point I call in a professional, a nephew of a friend on mine and see what he thinks. I'm a heat baby and like the house at 67 and my bedroom at 60 or less...I have a modified window unit for that. The house is all-electric and very well insulated, my largest electric bills are $200/mo for everything so I don't expect to see huge savings with a new heat pump. |

I happen to know a cheap skate that bought one of these, installed it, and then used an old refrigerator compressor to evacuate the lines. Then just put in the R22. Karl |

"Cross-Slide" wrote in message ... It sounds like the Compressor needs a capacitor also. Indeed, sometimes they use a common capacitor for fan and compressor.(three terminals- one common-one compressor-one fan) If you have an old analog ohm meter.........connect to common to one of the other terminals. The ohm meter needle should reduce ohms slowly. Reverse the leads of the meter on the same two terminals should repeat, then try the other two terminals. This not 100% test but will give you some idea if the capacitor has any capability. If you have a meter with capacitance test .......that would be even better. Hopefully the nephew will have some capacitors on the truck. Replacing the capacitor is the only true test. I have seem some test good and not start a compressor. Put a new one on and it ran like a charm. Good luck Lyndell |

I don't have a VTVM, but I do try to keep a
swing meter type VOM on hand for moments like that. It is very possible that the capacitors are the problem. On heat pumps, there should be two caps, one for the fan, other for the compressor. Window shaker AC use a dual capacitor. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Tom Gardner" w@w wrote in message ... Holy ****! Can I GET that lucky to just replace caps?

As to the "push fan to start", most often bad run cap.
Compressor doing the hum-click means either bad run cap, or bad compresssor. Of course, the cap is cheaper and easier. It can also be bad power feed, corrosion on a terminal. Power off, and clean the various connections that feed 220 VAC to the compressor. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Tom Gardner" w@w wrote in message ...

Have you ever had the outdoor unit professionally
cleaned? I have a friend in Tennesse, while I was at his place, I cleaned his heat pump. The running amperage went down about an amp. Saved him a bit of money, elctric wise.

"DoN. Nichols" wrote in message ... I *think* that the pressures sound reasonable for a non running compressor. Your static pressure is dependant upon temperature--it can be almost empty but as long as there is still a tiny amount of liquid remaining, the pressure will not drop. You will have a better feel for that when the compressor is running. If it is low, then in heat mode the outdoor unit will probably ice up rather quickly even under a fairly low humidity condition.....or it will trip the low pressure safety switch provided there is one installed. Did you even try to add any R-22? Proably not necessary. There is probably a charging chart glued to the inside of one of the condensor access panels. |

It will show you if the capacitor can actually pass the required current. You can build a simple one for under a buck: http://en.wikipedia.org/wiki/ESR_meter -- You can't fix stupid. You can't even put a Band-AidT on it, because it's Teflon coated. I prize my VTVM, it has class even if it is a dinosaur. I also have a bunch of DVMs, some as cheap as $5 each, some as much as $150. It all depends on which is closest. I used VTVMs for years, and built at least three of them but it won't give you accurate data on a capacitor that has to carry a heavy AC current. I think I still have two, if one survived the hurricanes a few years ago.. The other is here in the house. It has a huge meter movement, and compartments in the steel case to store the AC cord & probes. This cap has a feature, a "Physical interrupter for safety". Have you ever heard of that?

I saw that. The thermocouple is totally useful for reading
air temps in ducts, and also for helping calculate supeheat for HVAC / R systems. The sound meter may be useful for helping convince rock and roll bands to turn down the sound (well, maybe not?) Be interesting to read my lawn mower, snow blower, etc, and see what the dB levels are. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Michael A. Terrell" wrote in message ...

At 70F, your pressure should be a tad more than 10 lbs higher than that...and so either you have a bad thermometer or else the refrigerant is contaminated. It sounds like the Compressor needs a capacitor also. Thats a very real possibility. The house is all-electric and very well insulated, my largest electric bills are $200/mo for everything so I don't expect to see huge savings with a new heat pump. If using a heat pump in a relatively mild climate, your winter heating bill will be about 1/3 as high as it was with forced air electric strip furnace. Holy ****! Can I GET that lucky to just replace caps? I'll test them tomorrow with the "bounce method" on my VTVM...how many people still have one of those?.

From a bit of looking...the top of the cap swells and pushes up ripping loose the electrical leads. And yes, this cap's top is pushed up. |
