Parts for Bosch HMB57152UC/02: Motor Parts

This replacement cover restores the protective housing over internal components to keep wiring and parts shielded from debris and moisture. It helps maintain safe operation and prevents contaminants from entering sensitive areas. What it does:

• Provides a protective barrier over internal electrical and mechanical components
• Helps prevent debris, moisture, and accidental contact with wiring or moving parts
• Maintains the original enclosure fit and appearance for a clean repair
• Useful when a cracked, broken, or missing cover exposes internal parts

• One replacement cover

• Read your appliance service manual and disconnect power before beginning any repair
• Remove only the exterior panels required to access the damaged cover; keep fasteners organized
• Ensure the replacement snaps or screws into place securely and does not pinch wiring
• If you see additional damage or corrosion, inspect related components and replace as needed

The Magnetron is an OEM part for Bosch microwave ovens. It functions as the crucial high-frequency power unit responsible for efficiently generating microwave energy to cook and heat food. Working alongside the control board and tray turntable motor, it allows for fast, safe, and even cooking.

Symptoms of a failing magnetron include:

• Extended or incomplete cook times even on high-power settings 
• Abnormal noises emitting from within the unit during operation  
• Tripped internal circuit breakers and error code displays

Causes of failure relate to degrading electronic components after lengthy microwaving use. Exposure to moisture or contaminants may also accelerate wear. 

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

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.

This high-voltage capacitor stores and releases energy in the microwave's high-voltage circuit that powers the magnetron. Replacing a failed capacitor can help restore heating performance and reduce humming or breaker trips caused by HV faults. What it does:

• Works with the high-voltage transformer and diode to supply the voltage the magnetron needs for heating
• A weak or shorted capacitor may cause the microwave to run but not heat
• May lead to loud humming/buzzing, a blown internal fuse, or tripped circuit breaker
• Bulging, leaking, or burn marks on the capacitor indicate it should be replaced

• Includes 1 high-voltage capacitor

• Disconnect power by unplugging the unit or switching off the dedicated breaker before service
• High-voltage capacitors can retain a dangerous charge even when unplugged; discharge properly and follow safety procedures
• Document wire routing and terminal orientation before removal; transfer any brackets or clips from the original part
• After installation, ensure no voltage remains on the terminals before reassembly and testing

The Fuse is an OEM part for Bosch microwaves, crafted to safeguard the appliance by preventing electrical overload. This part acts as a protective barrier for the microwave, ensuring that if the electrical current exceeds safe levels, the fuse will blow, breaking the circuit to stop the flow of electricity. 

Causes of a bad Fuse in a microwave can include power surges, improper use of the appliance, or faults within the microwave’s electrical components, leading to excessive current flow. 

Symptoms of a bad Fuse in a microwave include:

• The microwave not turning on or completely unresponsive
• The appliance suddenly losing power without tripping any house circuit breakers
• An inability to start any cooking cycle despite the display being operational 

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

The Frequency Filter is an OEM replacement part for Bosch microwave ovens. Located inside the control panel casing, it prevents electromagnetic interference between electronic circuits. The frequency filter ensures precise cooking settings by filtering out radio waves and high-frequency noise.

Symptoms of a faulty frequency filter include:

• Settings appearing arbitrarily changed or unresponsive  
• Error codes signaling control malfunctions
• Microwave failing to heat or function as anticipated
• Buzzing, crackling, or whining noises emitting from inside

Causes of a bad frequency filter typically involve failures over extended usage. Repeated filtering can degrade or displace sensitive parts interfering with operations. 

Replacing your frequency filter restores reliable cooking and cabinet protection. This genuine Bosch component prevents future issues. Compatible with Thermador, Gaggenau, and select Kenmore microwaves.
