Product review (5 stars): Saved my five year old fridge
My five year old GE, side by side refrigerator (GSH22FXJMCC), started to work intermittently and within a week was not cooling at all.  This inverter board solved the problem.  These new modern refrigerators have gotten very sophisticated and have motherboards that control the system and variable speed compressors that are controlled by an inverter board (instead of the old style, single speed compressors that employ an inexpensive relay and start capacitor).  When they stop working, you either bring in an experienced tech or educate yourself on how modern appliances work and fail.  Anyway, after several days reading forums, watching YouTube videos, and checking voltages and resistance values on the motherboard, I felt comfortable that I understood what had failed.  I ordered the part at 11:30 pm on a Friday night and had the inverter in my hands by 11 am on Sunday morning.  Two day shipping added only ten bucks to the cost and was worth every penny.  I have to add that this GE fridge has a new design condenser coil that is not supposed to need cleaning, but it got dusty anyway, which caused the the compressor to run hotter, which in turn caused the inverter to cook itself (the inverter is mounted onto the compressor).  Clean your condenser coil at least once per year, regardless of what the salesman and the operating instructions say.  GE's new design is marginally cooled and cannot tolerate dust as well as the older design did.  GE has "value engineered" their appliances to the point that they are unreliable.  No more GE for me.
