Hmb5053u/01 Parts

This outer door panel replaces a damaged or worn front door panel to restore appearance and protection for the appliance. It provides the visible exterior surface and helps the door close and align properly. What it does:

• Replaces a dented, scratched or corroded outer door surface to improve appearance
• Protects internal door components and insulation from damage
• Helps the door sit flush and align with the cabinet to reduce gaps
• Restores a clean, finished look after collision or wear

• One outer door panel

• Turn off power to the appliance before starting any repair
• Remove inner door components and fasteners as required to access and swap the outer panel
• Keep screws and small parts organized; some trims or handles may need separate removal

This turntable motor powers the rotating glass tray in compatible countertop and built-in microwaves, restoring even cooking and proper tray rotation. Designed as a direct replacement for the microwave's internal platter drive. What it does

• Spins the microwave turntable so food rotates for more even heating
• Replaces a motor that is noisy, stops turning, or turns intermittently
• Restores proper tray alignment and prevents off-balance wobble caused by a failed motor
• Works with the microwave's drive coupler and glass tray assembly to resume normal operation

• One turntable motor

• Disconnect power at the breaker or unplug the appliance before servicing
• Remove the turntable and roller ring to access the motor from inside or beneath the cavity per your model's service guide
• Handle glass tray and roller ring carefully to avoid breakage; test rotation after reinstalling 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.
