A Whirlpool refrigerator on Airport Road in Carrollton, OH was developing frost in the freezer with the fan starting to hit ice buildup inside a plastic cover. The homeowner had experienced this issue before with a bad thermostat, but this time we found a failed defrost terminating thermistor and a plugged defrost drain.
The Problem
The customer reported their freezer was developing frost, and ice buildup inside a plastic cover that the fan was starting to hit. They had this issue several years back and it turned out to be a bad thermostat. The fridge stayed cold and freezer items remained frozen, but the fan was making noise from hitting ice.
Diagnosis
I took the refrigerator apart and found some ice across the top of the evaporator. Upon further investigation, I found that the defrost terminating thermistor had failed. During an earlier visit, I also discovered the defrost drain was plugged, which was causing ice to collect on the evaporator. The defrost heater tested good.
The Repair
- Parts replaced: WPW10383615 — Defrost terminating thermistor
- Work performed: Cleared plugged defrost drain obstruction and replaced failed thermistor
- Result: Unit operating correctly with ice buildup resolved
Is It Worth Repairing?
This Whirlpool refrigerator model is generally reliable and worth repairing when components like the defrost system fail. The defrost terminating thermistor is a relatively inexpensive part, and these units typically provide years of additional service after proper repairs. Given that the compressor and main cooling system were functioning properly, this repair made good economic sense.
Maintenance Tips for Whirlpool Refrigerators
- Clean condenser coils every 6 months to prevent overworking the defrost system
- Check door seals regularly and clean door gaskets to maintain proper temperature
- Keep defrost drain clear by pouring warm water down the drain hole periodically
