Parts for Bosch HMB50152UC/05: Service Kit / Turntable Parts

The Turntable, Tray is an OEM component specifically designed for Bosch built-in and over-the-range microwaves. Comprised of a durable glass plate and integrated motor, it facilitates even heat distribution essential for quick, consistent cooking. The turntable provides users control over customized cooking abilities.

Causes of damage can include cracks developing from years of extreme temperature changes. Deterioration of motor couplings from prolonged use may also diminish rotation essential for microwave performance. 

Symptoms of a bad turntable tray include: 

• Vibrating or grinding tray unable to smoothly revolve
• "Lopsided" heating leading to cold or hot spots in food 
• Cracked or loose turntable trays potentially present safety concerns
• Malfunctions requiring replacement rather than a simple fix

Replacing with this genuine Bosch turntable restores the intended function. Compatible with some Blomberg, Miele, and Thermador microwave models, optimized operation maintains ease and convenience for home-cooked nutrition with OEM reliability.
 

This turntable ring supports the microwave's glass tray so it turns smoothly for even heating and prevents wobble. Durable rollers reduce friction and keep the tray centered for quiet, reliable operation. What it does:

• Supports and guides the glass turntable so it rotates evenly.
• Replaces worn or broken roller rings that cause the tray to wobble or bind.
• Reduces grinding or scraping noises from a misaligned turntable.
• Helps restore proper tray movement for consistent heating.

• Always unplug the appliance before servicing to avoid electric shock.
• Remove the glass tray, lift out the old ring, place the new ring on the turntable support, then replace the glass tray.
• Handle the glass tray carefully to avoid chipping or cracking; no special tools usually required.

The Switch Assembly is an OEM part for Bosch microwaves. It plays an important role in controlling the various functions of the microwave such as power levels, time settings, warming functions, and more. The switch assembly receives input signals from the control panel and relays them to other internal components to initiate the appropriate cooking program.

Causes of a bad switch assembly can include worn out or faulty electrical components, damage from moisture intrusion or spillage inside the microwave cabinet, or repeated use over time deteriorating connectivity. 

Symptoms of a bad switch assembly include:

• Buttons or dials not functioning properly 
• Preset programs not working as intended
• Microwave failing to turn on
• Inability to change power levels or time settings

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

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.
