My french door fridge stopped cooling. When the compressor itself is allowed to cool, it will start and cool the fridge to specified temps and shut off, as it should. Later, when the warm/hot compressor tries to come on again, the relay buzzes, and the compressor will not start. If unplugged and allowed to cool again, the compressor will start.... I have replaced the relay unit - no change. I know the compressor failing is the likely trouble, any other possible causes for a short-cycling compressor? Is it possible the compressor is being asked to come on too frequently? What would cause that? The defrost circuit tests OK (all the tests when the unit is in service mode look OK). I'm hoping because the compressor runs, it's something else causing the problem. Am I dreaming? What to test next?

My ohm meter gave me readings of 5.9 start to common, 4.7 run to common, and 10 run to start. That seemed OK to me. What do you think?

Could it be a sealed system restriction? That's not something I could test, but how is that usually checked?

When cool the compressor starts every time and takes the fridge/freezer to operating temps (38 and 0), which, after reading your post, I confirmed with a second thermometer and not just with the fridge’s own display. It’s restarting to maintain the temps where the problem arises. Today I noted when the fridge/freezer reached the proper temperatures and listened for the compressor to shut off. It shut off about 30 minutes after the freezer digital temp was 0 and right about exactly when the secondary thermometer reached zero. 15 minutes later, without ever opening a door, the compressor tried to come on again, the relay buzzed and the compressor did not start. About 60-90 seconds later it tried again. And 60-90 seconds again.... Then I shut if off. It seems like the compressor is being asked to come on too soon/often. We have frequent power interruptions in my area, could this have taken a toll on the main board (I see no physical damage on it)?


The compressor doesn’t cool enough to start before being asked to come on again. Frustrating.

Well, none of that sounds too good. Would those things also make the compressor come back on so quickly after cooling the fridge and freezer down to their preset levels?
