WP67004757 – Genuine OEM Whirlpool Refrigerator Defrost Thermostat

The WP67004757 Genuine OEM Whirlpool Refrigerator Defrost Thermostat is a factory-original thermal control component designed for Whirlpool refrigerators and compatible brands including Maytag, Amana, Jenn-Air, Kenmore, KitchenAid, and others. This OEM defrost thermostat is engineered to regulate evaporator temperature during the defrost cycle, ensuring frost does not accumulate excessively and that cooling performance remains stable. Available from Appliance Kingdom (Canada), this part ships nationwide with fast delivery, making it a reliable replacement choice for both homeowners and appliance repair professionals.

A failing defrost thermostat is one of the most common causes of refrigerator cooling issues such as frost buildup and inconsistent temperature regulation. Replacing it with a genuine OEM part helps restore proper defrost cycle operation and long-term appliance reliability.

Function & Importance of the Defrost Thermostat

The defrost thermostat is a safety and control device mounted on or near the evaporator coil inside the refrigerator compartment.

Its primary functions include:

• Monitoring evaporator coil temperature during the defrost cycle
• Turning the defrost heater ON when coils are cold enough and OFF when frost is melted
• Preventing overheating of the evaporator system
• Ensuring efficient airflow and consistent cooling performance

OEM quality is critical because this component directly controls heating cycles. If it fails, the refrigerator may either over-defrost (causing overheating issues) or fail to defrost at all (leading to ice buildup and airflow blockage).

Common Symptoms of a Faulty Defrost Thermostat

When the WP67004757 begins to fail, you may notice:

• Heavy frost or ice buildup on evaporator coils
• Refrigerator or freezer not cooling properly
• Fridge section warm while freezer still runs
• Restricted airflow inside the refrigerator compartment
• Refrigerator running continuously without reaching set temperature
• Intermittent cooling performance
• Water leakage from excess ice melt during manual defrosting

These symptoms often indicate a defrost system failure, and the thermostat is one of the key components to check. Replacing it can restore normal defrost cycling and cooling efficiency when confirmed as the fault.

Compatibility Guidance

This defrost thermostat is designed for use in Whirlpool refrigerator systems and select compatible brands.

Before purchasing:

• Always verify your refrigerator’s model number
• Confirm part number WP67004757 is listed for your specific appliance
