Bosch Defrost Heater 00677518 OEM Part

Refrigerator Defrost Heater Overview:

The Heater-Defrost is an original equipment manufacturer (OEM) component, specifically engineered for Bosch refrigerators. This crucial element facilitates the automatic defrost process, eliminating the necessity for manual intervention by melting ice within the freezer section.

Functionally, the defrost heater elevates the freezer's internal air temperature just above freezing, effectively preventing ice formation.

Typical signs of a faulty defrost heater include:
- Excessive ice accumulation behind the evaporator coil
- Frost or moisture appearing on shelves and walls inside the freezer
- The freezer's inability to maintain the designated temperature
- Inconsistent operation or unexpected shutdowns of the refrigerator

Several factors can impair the heater-defrost's performance, such as mineral build-up, physical damage disrupting airflow, or general degradation of the heating coil from repetitive usage.

This particular Bosch defrost heater is also compatible with models from Thermador, Gaggenau, and certain Kenmore lines.
