Woodie for Model Number WZF34X18DW00

Why is my upright freezer not defrosting the evaporator coil? The symptom: Freezer fan is running but food is no longer staying frozen. Accessed evaporator coil and found it to be iced up. Removed all ice and restarted freezer. Temperature returns to about 0 to 4 degrees F when at recommended setting. Food stays frozen. Approximately 4 weeks later the freezer has iced up again and food is no longer frozen solid. Freezer is about 4-5 years old. Heating element reads 36.1 ohms. Heats properly when connected directly to house current. Thermistor on evaporator coil reads 2.94 KOhms at 75F, 8.48 KOhms at 33F (ice water) and 20.88 KOhms at 3.2 F (in a different freezer). Thermistor in the food area reads 2.82 KOhms at 75F, 8.66 KOhms at 33F and 21.11 KOhms at 3.2F. Door seal appears to be in excellent shape. Do these parts appear to be working correctly? If they are working as they should, what else can it be? Is there a way I can diagnose a problem with the Freezer Control Box?

Answer

Woodie, check the freezer defrost thermistor part [AP6020675,its mounted on the evaporator coil,, it can be checked with a multi meter and has values of 2700 ohms at 75 degrees and about 8000 ohms at 32 degrees (in ice water), also it has to be snug to the tubing otherwise the control board will think in the defrost cycle the evaporator coil is warmer (defrosted ) then it actually is,.
