00677518 Bosch Refrigerator Defrost Heater

Refrigerator Defrost Heater Overview:
The Heater-Defrost is an original equipment manufacturer (OEM) part designed for use in Bosch refrigerators. This component is essential for the automatic defrost cycle, helping to prevent the need for manual defrosting by melting ice in the freezer compartment.

During its operation, the defrost heater raises the air temperature inside the freezer to slightly above freezing, ensuring that ice does not accumulate.

Common indicators of a malfunctioning heater-defrost include:
- Significant ice buildup behind the evaporator coil
- Presence of frost or condensation on the freezer's shelves and walls
- Inability of the freezer to maintain the correct temperature
- Refrigerator operating inconsistently or stopping abruptly

The effectiveness of the heater-defrost can diminish due to mineral deposits, physical damage that affects air flow, or wear and tear on the heating coil from repeated use.

This specific Bosch heater-defrost part is also suitable for use in Thermador, Gaggenau, and select Kenmore models.
