Product review (5 stars): Easy fix for my 12 year old kenmore refrigerator
Easy fix for my 12 year old kenmore refrigerator.  Compressor would try to start, buzz and 1-2 mins later, overload relay would click-- then repeat.  After checking the web, found start cap / overload relay as probable cause.  Supco 3 N 1 replaces all this in 1 device.  Wired it in as shown, fixed the fridge for $10!
