Bosch produces items under the Bosch, Thermador, and Gaggenau labels. The Relay, an original equipment manufacturer (OEM) part, is crafted specifically for Bosch microwaves. Serving as a critical safety component, it regulates the microwave's internal temperature to thwart overheating. If a hazardous temperature level is attained, the relay thermostat disconnects the power to the heating element or magnetron, halting the cooking activity to prevent potential damage or fire hazards.
Replacement of the thermostat might be required if it becomes too sensitive or malfunctions, often caused by consistent exposure to high temperatures or an extreme overheating incident.
Indicators that a Relay may be failing include:
- The microwave stopping operation unexpectedly during use, even if the cooking process is incomplete.
- The microwave failing to start, possibly due to the thermostat remaining permanently open, detecting an overheat status even when the appliance is cool.
- Uneven cooking results, where the microwave heats sporadically or not at all, implying an early power disconnection by the thermostat.
This authentic OEM Bosch component is also suitable for certain models from Thermador, Gaggenau, and Kenmore.
