A failing defrost heater or thermostat assembly is one of the most common causes of frost accumulation and cooling failure in Whirlpool refrigerators. Replacing it with a genuine OEM assembly helps restore proper airflow, temperature stability, and overall appliance efficiency.

Function & Importance of the Defrost Heater & Thermostat Assembly

The defrost heater and thermostat assembly plays a critical role in the refrigerator’s automatic defrost system. During normal operation:

• The defrost heater melts frost buildup on the evaporator coils
• The thermostat monitors coil temperature and shuts off the heater once frost is cleared

Together, they prevent ice buildup that would otherwise block airflow inside the freezer and refrigerator compartments.

OEM-grade accuracy is essential because incorrect heating cycles or faulty temperature sensing can lead to overheating, poor cooling performance, or repeated frost accumulation. Genuine Whirlpool parts ensure proper electrical resistance, safe operation, and correct cycle timing.

Common Symptoms of a Faulty Defrost Heater & Thermostat Assembly

A failing WP61006198 assembly may cause:

• Excessive frost or ice buildup on evaporator coils
• Refrigerator not cooling properly while freezer may still run
• Freezer too warm or inconsistent temperatures
• Refrigerator section warming up despite compressor running
• Reduced airflow due to ice-blocked evaporator
• Refrigerator running continuously without reaching target temperature
• Water leakage or overflow from defrost drain issues
• Repeated frost re-formation after manual defrosting

These symptoms are commonly linked to defrost system failure in Whirlpool refrigerators. Replacing this assembly often restores proper cooling when the issue is confirmed in the defrost circuit.
