I have a Kenmore side by side refrigerator and freezer. The other day, the fridge and freezer stopped cooling. After searching the forums, I decided to remove the starter relay and test the compressor pins for continuity. It is an Embraco model FGS 80 HA compressor. The pins are arranged as an upside down triangle. Between the top two pins continuity measured 6.2 Ω. Between the bottom and top left pin 3.0 Ω, and between the bottom and top right 3.5 Ω. From what I have read these are within the correct ranges.

When shaking the start relay, there is a slight rattle. However, when the fridge is plugged in the compressor vibrates and warms up. However, the unit does not get cold. Any advice is appreciated. Thanks.

Since the compressor is running and you are not getting cooling you have a sealed system problem.

You have to be sure that there is no cooling. If there is some cooling then it may not be a sealed system problem.

I am assuming that the condenser/compressor fan and the evaporator/freer fan are running.

A sealed system problem will be an expensive repair as you need a pro. Often it makes more sense to put the dollars towards a new unit.
