Liebherr 694168901 Defrost Heater 115 Volts

Product Description

The LIEBHERR 694168901 is a defrost heater rated at 115 volts, designed as a direct OEM-style replacement component for LIEBHERR refrigeration appliances. The defrost heater energizes during the automatic defrost cycle to melt frost accumulation from the evaporator coil, maintaining proper airflow and cooling efficiency. Correct heater function is critical to preventing ice buildup that can restrict airflow, overload the evaporator fan, and degrade refrigerator performance. This part is installed by appliance service technicians during scheduled maintenance or diagnostic repair when the defrost system fails to clear frost from the evaporator assembly.

This defrost heater is intended for use in LIEBHERR home refrigeration equipment operating on a standard 115-volt residential electrical circuit. It is suited for automatic defrost refrigerators and freezers where the defrost heater is a separate, serviceable component within the evaporator compartment. Technicians typically encounter this part when diagnosing excessive frost buildup, abnormal compressor run times, or failed defrost termination caused by a burned-out or open heater element.

Key Features

• Rated at 115 volts for compatibility with standard residential electrical systems
• Designed as an OEM-style replacement for LIEBHERR refrigeration appliances
• Restores proper automatic defrost cycle function to the evaporator assembly
• Replaces a failed or open heating element causing frost accumulation on the evaporator coil

Compatibility

Designed as an OEM-style replacement defrost heater for LIEBHERR home refrigeration appliances. Verify fitment against the appliance model number and service documentation before installation.

Installation Notes

Installation should be performed by a qualified appliance service technician. Disconnect power to the refrigerator at the outlet or circuit breaker before accessing the evaporator compartment. Remove all food, shelving, and interior panels as required to reach the evaporator assembly, and handle the heater element carefully to avoid damage to the glass or sheath. Confirm the defrost thermostat and defrost timer or control board are also tested before reinstalling panels, as a failed heater is often part of a broader defrost system fault.
