Whirlpool Refrigerator Defrost bi-metal thermostat WPW10165425, Replaces W10165425, 12639324SP

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Freezer does not defrost properly
• Visible frost buildup on the evaporator or freezer back panel
• Refrigerator section becomes too warm when airflow is restricted by frost
• Refrigerator may run excessively while cooling performance declines

Check Before Replacing

• Disconnect electrical power before accessing the component or its wiring.
• Inspect for heavy frost covering the evaporator; frost buildup can restrict airflow but does not by itself prove the thermostat is defective.
• With the thermostat isolated from the circuit and cold enough for defrost operation, check continuity with a multimeter; the thermostat should close when cold. An open reading when properly cold indicates a possible fault, but other defrost-system components should also be evaluated.
• Check the defrost heater and wiring separately rather than assuming the thermostat is the cause of a no-defrost condition.

Installation Notes

• Disconnect refrigerator power before service.
• Access is typically through the freezer evaporator area; the exact access sequence varies by refrigerator model.
• The thermostat must be positioned in its intended contact location on the evaporator assembly so it can sense evaporator temperature correctly.
• Reconnect the wiring securely and reinstall removed panels before restoring power.
• Use the model-specific service information for access details and any required wiring-connector procedure.
