Is This the Right Part?
✅ Cross Reference Information
Common Symptoms
- Frost buildup
- Fresh-food section too warm
- Freezer section too warm
- Leaking water
- Fresh-food or freezer section too cold
Check Before Replacing
- If the model has a display and shows the lowercase “dE” code, treat it as an indication that the defrost system has not operated properly; it does not identify this thermostat as the failed component.
- With power disconnected, inspect the evaporator area for abnormal frost accumulation before replacing parts.
- Verify actual compartment temperatures using the model’s temperature-check guidance; do not rely only on fluctuating air temperature.
- Because several defrost-system components can produce similar symptoms, have the heater and defrost control evaluated before concluding that this thermostat is defective.
