I had a host of issues with this fridge. I bought it off Craigslist and "it works great". Lol, ya right. The evaporator fan was dead. Replaced it with new fan. Stopped getting as cold as it should. The heater element burned open, repalced the heater. Seemed to have defrost issue (in defrost too long). Replaced ALL thermistors (had the old defective rounded type). Also replaced defrost thermostat. Still seemed to be in defrost too long. Now the evap fan runs at rapidly changing speeds. Ice cubes clump in ice bucket. One thing left to repalce.. the circuit board. Seems to have fixed ALL of my problems. Easy to replace. 1/4" nut driver and needle nose pliers. Works great now! Thanks!!
