Bosch 776275 Defrost Heater

Product Description

The BOSCH 776275 is a defrost heater element designed to clear frost and ice accumulation from evaporator coils in refrigeration appliances. Defrost heaters cycle on during the appliance defrost period to melt frost buildup that would otherwise restrict airflow and reduce cooling efficiency. This part is sourced as a Bosch OEM replacement component and is installed by appliance service technicians during routine defrost system diagnostics or heater failure repair.

This defrost heater is suited for use in residential refrigeration appliances where the factory defrost heater has failed or is no longer cycling correctly. Typical symptoms that point to a defrost heater failure include excessive frost buildup on the evaporator coil, warm compartment temperatures, or a defrost system that does not complete its cycle. Installation is performed as part of a full defrost system service, which often includes checking the defrost thermostat and defrost timer or control board as well.

Key Features

• OEM Bosch replacement defrost heater for direct-fit installation
• Designed to melt frost accumulation from evaporator coils during defrost cycles
• Supports proper airflow and cooling efficiency when operating correctly
• Part of the defrost system alongside the defrost thermostat and timer or control

Compatibility

Designed as an OEM-style replacement defrost heater for Bosch residential refrigeration appliances. Confirm fitment using the appliance model number before ordering.

Installation Notes

Installation should be performed by a qualified appliance service technician. Disconnect power to the appliance at the outlet or circuit breaker before accessing internal components. Remove all food and allow any remaining frost to melt fully before beginning disassembly of the evaporator panel. Inspect the defrost thermostat and defrost control for faults at the same time to avoid a repeat service call.
