Product review (5 stars): Quick Fix and Saved Hundreds
My refrigerator was running but just blowing warm air inside the fridge.  Everything else worked, just no cooling.  I rolled out the fridge and saw that fan was running but the compressor was not.  After lots of Googling, I guessed this part was bad.  A quick multimeter test confirmed that no voltage was going to the compressor.  The part arrived quickly and within a few minutes, the fridge was back up and cooling.  I just hope it lasts a while.
