Frigidaire FRS23H5ASB8 has Intermittent Compressor
Posted 27 December 2011 - 02:10 AM
When the box is warm the evaporator and condensor fans are running and the compressor does the hum and click thing trying to start. A few weeks ago I replaced the start relay and the capacitor but the problem came back after a little over a week. The condenser fan and coils are clean. When the compressor is running, both sides stay at proper temperature until the next time the compressor stalls.
This morning the box was warm again(it's been 10 days since the last time). I turned off the refrigerator and about 5 hours later started it back up and it's working fine again. I am watching the evaporator coils in the freezer section, and they seem to be icing up with a thin film of frost over the entire evaporator. Earlier this evening I was able to feel the evaporator defrost heater getting warm when the unit was working properly and cooling.
As near as I can tell everything is working now until the next intermittent problem. What can I look at in the meantime, and what should I check the next time the problem comes back. Any ideas on what could be the problem?

I've seen the exact same problem/complaint on a SxS Frigidaire of a very similar model and vintage, (yours appears to be around a 2003 from the dates in the parts breakdown pictures).
Frigidaire's have a very bad track record on sealed system/compressor problems. I not surprised at all when I see a Frigidaire that is only a little over 6-7 years old failing because it's out of freon or the compressor is having problems, (mostly low on freon - I haven't had that many with actual failing compressors as you're experiencing).

Update: The compressor is running this morning, the temperature in the beer side is 30 degrees, and there is a light film of ice on the the entire evaporator. All appears to be well for now, but I expect the compressor to do the hum click thing in a week or so.
The compressor is a Tecumseh that's made in Brazil. How much crappier can that get? Maybe if they had some goat lover build it in Turdistan? I used to sell industrial refrigeration systems and back then I had a lot of customers who refused to buy anything with a Tecumseh in it. I can't believe Tecumseh is still in the business. I noticed that one source for replacements sells Panasonic. Are those any good? I have been away for a while and didn't have a lot of experience with hermetics anyway.

Someplace I think I saw reference to the idea that liquid refrigerant may be getting back to the compressor because the ADC isn't working right. Wish I could find it and post a link. Seemed like it was a source of a lot of problems if not in Frigidaire, but in some other makes as well.

1.send power to the compressor.
2. send power to the defrost system.
After defrost the adc times out to send power back to the compressor.
They can act intermittently due to a defective board or loose or corroded wire terminals.
The cold control can also be intermittent in operation.
Your compressor runs days at a time with no issue.
My focus would be on the 2 parts discussed above.

Side observation, not necessarily related to the ADC, one of the recent compressor lock ups occured at the same time we had a 3 hour power failure during a windstorm.
I think I need to do some focused research on this ADC module.

If the ADC is intermittent, the check for heavy frost on the evap, when the failure occurs, also check to make sure you've got power to the compressor, when its doing the buzzing bit. I would also do and amp draw on the compressor when it's doing the buzzing thing, if it's close to the LRA number, its proably bad. The little blue indian is no ones friend.
