Hello, the compressor on my refrige is not turning on.
I replaced the main board with no success.
I have visually inspected several parts and can’t identify any issues.
In a prior thread it was suggested that it probably was an inverter problem.
I know I probably need to buy and learn how to use a voltage meter.
In the mean time, if it helps to diagnose the issue - I realized today that when I plug the refrige in, there is an immediate click and the whole refrige shakes. I assume it is the compressor trying to come on, but failing.
When you plug in the new inverter, listen and feal the compressor. If vibrating excessively or making unusual noises, you might have a problem with one of the phase windings that will eventually blow out the inverter again.
You might also want to purchase an amprobe to see if the total single phase compressor current is higher than the nameplate rating. Current should be between one and 1.6 amps.
I wanted to thank you again. richappy, I installed the inverter last night and the refrigerator cooled to it target temps (0/37) in about 8 hours. In fact, I’m a little concerned this AM because it says it’s at -2 and 34 degrees. It exceeded it’s goal.
The inverter I received from APP had one connector that didn’t match the original part. I noticed someone else had the same problem.
I didn’t understand the APP reply, but to resolve it, I cut off the connector from the old inverter and used it on the new one. So far it appears that the risk of doing this paid off ok. I couldn’t see the harm in it as it seemed to be a very simple connection (2 wires). Hopefully time doesn’t prove me wrong on that.
Interestingly, after replacing the part, when I first plugged it in, it started up smoothly and quietly. There was no jarring motion. With regards to the compressor, there is very little vibration at all. Very quiet. This is in stark contrast to when the inverter was bad. Plugging it in with the old inverter would cause the whole refrigerator to shake intensely, but briefly. Again, I assume this was the compressor attempting to kick-in and failing. I wanted to mention this in hopes that it helps people diagnose their own refrig issues.
