Common Symptoms
- Freezer evaporator coils heavily frosted or iced
- Refrigerator not defrosting
- Freezer runs continuously or for unusually long periods
- Refrigerator may not cool properly because airflow is restricted by frost
Check Before Replacing
- Disconnect power before accessing the thermostat.
- Inspect the evaporator area for excessive frost or ice buildup.
- Check thermostat continuity only under the temperature conditions specified by the appliance’s service documentation; a continuity result at room temperature alone is not sufficient to confirm failure.
- Verify the refrigerator model number before ordering because compatibility is model-specific.
Pro Tip
Confirm the exact refrigerator model before purchase; this thermostat is used across multiple Whirlpool-family and Kenmore appliances.
