The Diode is an OEM part for Bosch microwaves. This small electronic component regulates electricity flow to heating components.

Causes of failure may relate to stresses from continuous power pulsing. Microwave emissions fluctuate temperatures inside rapidly over time stressing connections.

Symptoms of a bad diode include:

• Inconsistent or incomplete cooking from uneven power distribution
• Failure to properly distribute full heating wattage for expected results
• Error code displays or failure to start due to electrical faults in related boards

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.
