Product review (5 stars): My GE Hotpoint model no: HSS25IFMD WW fridge has ...
My GE Hotpoint model no: HSS25IFMD WW fridge has gone out several times. The first time, it was the main board.

It recently had a defrost issue again. I assumed the problem was the same as before, so I made the mistake of replacing the main control board again prior to first replacing several smaller, inexpensive parts. The board and the heating element were replaced but did not fix the problem. Then I replaced the defrost thermostat and the freezer temperature sensor. I'm not exactly sure which one of these two fixed my defrost problem, but since they were both inexpensive, I replaced both. My fridge works perfectly again.

A couple things to keep in mind, you will need some wire strippers, wire nuts, and electrical tape to do these repairs correctly. Replacing this part is not time consuming or labor intensive at all. For installation instructions, search Youtube for installation videos.

***IMPORTANT***
Make sure you defrost the freezer coils before you expect this repair to take effect.

My defrost problem was as a result of my freezer not going into defrost mode as it should. After installing these new components, I expected the defrost cycle to start immediately, which would have been evident by seeing the defrost heater come on. This did not happen which made me sick, because I thought my repair was a failure. It was not until I defrosted the freezer coils and started the freezer again that I saw the freezer go into defrost mode correctly.
