I replaced the 2 thermistors (temperature sensors) in the refrigerator earlier in the year and all worked good. Then it got warm in the refrigerator again so I decided that since my refrigerator is about 11 years old I will just replace most of the electrical parts so it would be like new again and I don't have to dig into it anymore. I replace the 2 thermistors (temperature sensors) in the freezer, the evap. thermodisc, the thermostat, the defrost heater, and the board asm main control. I had 14 people over Thanksgiving and it performed perfect. It's only been a few days since the repairs but it seems like new again. A note that I couldn't seem to find is that on the back plate of the freezer there is a rivet that does need to be drilled out in order to get to most of these parts.
