WPW10165425 - Genuine OEM Whirlpool Refrigerator Bimetal Defrost Thermostat

WPW10165425 – Genuine OEM Whirlpool Refrigerator Bimetal Defrost Thermostat

The WPW10165425 Genuine OEM Whirlpool Refrigerator Bimetal Defrost Thermostat is an original manufacturer temperature-sensing safety component designed for Whirlpool refrigerators and compatible refrigerator systems. This genuine OEM part is engineered to precisely regulate the defrost cycle by sensing evaporator temperature and controlling when the defrost heater turns off. Available from Appliance Kingdom with fast Canada-wide shipping, this part is essential for restoring proper defrost performance and preventing frost buildup issues commonly seen in failing refrigerator systems.

Function & Importance of WPW10165425 Defrost Thermostat

The defrost bimetal thermostat is mounted on the evaporator coil inside the freezer section. Its main function is to monitor coil temperature during the defrost cycle.

When the refrigerator enters defrost mode, the heater melts ice buildup on the evaporator coils. The WPW10165425 thermostat ensures the heater shuts off once the correct temperature is reached, preventing overheating and protecting internal components.

Using a genuine OEM part is critical because it ensures:

• Accurate temperature sensing
• Safe defrost heater shutdown
• Proper system cycling
• Long-term reliability of the refrigeration system

If this thermostat fails, the refrigerator can lose its ability to properly defrost, leading to airflow restriction and cooling inefficiency.

Common Symptoms of a Faulty Defrost Thermostat

A failing WPW10165425 bimetal thermostat can cause several refrigerator performance issues, including:

• Excessive frost or ice buildup on evaporator coils
• Refrigerator not cooling properly even though the freezer may still run
• Warm refrigerator compartment
• Inconsistent or fluctuating internal temperatures
• Defrost cycle not functioning correctly
• Compressor running longer than normal
• Restricted airflow due to frozen evaporator coils

These symptoms often appear gradually as frost accumulates and airflow becomes blocked. In many cases, replacing a faulty defrost thermostat restores normal defrost operation and cooling performance.
