Whirlpool WPW10140161 Defrost Heater Refrigerator

Product Description

The Whirlpool WPW10140161 is a genuine OEM defrost heater designed for use in refrigerator and freezer systems. The defrost heater activates during scheduled defrost cycles to melt frost accumulation off the evaporator coil, maintaining efficient heat exchange and preventing airflow restriction. Without a functioning defrost heater, frost buildup on the evaporator will reduce cooling performance and can eventually cause the unit to stop cooling entirely. This is a direct OEM replacement part sourced from Whirlpool, ensuring proper fit and function for compatible models.

This defrost heater is intended for residential refrigerator applications where the automatic defrost system has failed due to a burned-out or open-circuit heater element. It is typically installed by appliance service technicians during a defrost system diagnostic that has confirmed heater failure through continuity testing. Compatible systems use an automatic timed or adaptive defrost control board to cycle the heater during off-compressor periods.

Key Features

• Genuine OEM part manufactured by Whirlpool for direct replacement
• Restores automatic defrost cycle function to the evaporator assembly
• Prevents frost accumulation on the evaporator coil that restricts airflow and reduces cooling efficiency
• Designed for precise fit within compatible Whirlpool refrigerator evaporator compartments

Compatibility

Genuine OEM replacement defrost heater designed for compatible Whirlpool refrigerator and freezer models equipped with an automatic defrost system. Verify model number compatibility before installation.

Installation Notes

Installation should be performed by a qualified appliance service technician. Disconnect power to the refrigerator at the outlet or breaker before accessing the evaporator compartment. Remove all food and allow residual frost to clear before disassembly of the evaporator cover panel. Confirm heater failure with a continuity test before replacing to avoid misdiagnosis of the defrost thermostat or control board.
