Mbes/01 Parts

This microwave magnetron generates the radio-frequency energy that heats food. Replace a failed unit to restore proper cooking performance when the microwave runs but no longer heats or heats weakly or intermittently. What it does:

• Produces microwave energy that is directed through the waveguide into the oven cavity
• Common failure symptoms: runs but won't heat, weak or intermittent heating
• Presents with an unusually loud humming/buzzing during operation
• Restores proper cooking power when the original magnetron has failed

• One magnetron assembly

• Disconnect power before service; high-voltage components can retain a dangerous charge—discharge the HV capacitor safely
• Note magnetron orientation and transfer any brackets/screws from the original as required
• Avoid touching the antenna tip; ensure the waveguide seal seats correctly and the cavity/waveguide cover is clean and intact
• After reassembly, test with a cup of water and verify proper airflow and normal sound

The PC Board is an OEM component specifically designed for Bosch microwaves. As the central control unit, the PC board regulates and monitors the functioning of the microwave features and components. 

Symptoms of a bad PC board include:

• Lights or display not working properly  
• Inability to start or stop the microwave
• Failure of sensor or preset cooking functions
• Random or unexpected operation of buttons/dials

Causes of a bad PC board can be damage from power surges, spilled liquids inside the unit, or normal wear and tear over several years of use.

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