I ordered a freezer temperature control. I ordered from you because parts are certified. Last thing I wanted was to go through the replacement process with a part that didn’t work. I’m not a handy person by nature, and I have zero common sense. I watched the awesome instructional video that you provided with my order several times. Before receiving or even opening the package, I felt that I knew what to expect because I watched the video so many times. Before beginning, I made sure I had as... Read more

Condenser was encased in solid block of ice due to automatic defrost not working. Replaced thermostat and ADC control board. Working fine now. Most tedious part was using a heat gun to melt all the ice off the condenser coils. You will need a couple small wire nuts to splice the new thermostat into the existing harness (they are not included). Service tech wanted over $400 to repair, fixed it myself for half that. Thanks !
