Product review (5 stars): just what the fridge doctor ordered.
was the cause of my mini fridge starting only once, and then dying.  Some of the starters have this built into the three prongued motor mounting point.  But this is usually the culprit if you have a unit that will start up once, but not after it's down to temp.  It's dead.  And this is cheap compared to a whole new fridge. Total time of installation was about 10 minutes., including testing.
