Description
The Defrost Heater is an OEM part for Bosch refrigerators. Strategically placed at the rear of the freezer compartment, it quickly removes frost and ice during automatic defrost cycles. The defrost heater utilizes precisely regulated currents to raise temperatures temporarily and expel moisture.
Causes of a bad defrost heater may involve failures due to regular heating and cooling over countless cycles. Mineral or ice deposits can restrict filaments or warp sensitive components within.
Symptoms of a bad defrost heater include:
- Frost buildup despite automatic defrost mode being set
- High energy bills indicating excess run-time to fully defrost
- Warm areas detected behind removable freezer panels
- Risk of frost and condensation dripping onto stored items
Replacing your malfunctioning heater ensures even temperatures throughout. This genuine Bosch part restores frost-free convenience and maintains cooling efficiency. It is compatible with some Thermador, Gaggenau, and Kenmore models.
