Parts for Bosch HBL8751UC/01: Base Assembly Parts

Fix loud grinding noises or overheating in your microwave with this cooling fan blade. Common repair for ventilation issues. Moderate DIY difficulty.

This fan motor circulates air through the appliance to cool internal components and maintain proper operating temperature. Replacing a worn motor restores airflow and can reduce overheating or abnormal noise. What it does:

• Spins the condenser/blower fan to move air over coils and heat-producing parts
• Restores airflow when a motor has failed or slowed
• Commonly linked to symptoms like loud grinding or squealing, reduced/no airflow, or overheating
• Helps the appliance maintain proper temperatures for reliable operation

• One fan motor (single unit as pictured)

• Disconnect power before servicing to avoid shock or injury
• Inspect mounting, fan blade, and wiring harness for damage before installing
• Use the correct connector and secure mounting to prevent vibration and noise

This temperature regulator is the oven's thermostat. It senses cavity heat and cycles the heating source to hold the set temperature, helping restore accurate baking performance and more consistent cooking results.

• Monitors oven temperature via its sensing bulb/capillary and controls the heating circuit
• Helps maintain the set temperature during preheat and baking
• Common symptoms of a failed regulator: oven runs too hot or too cold, never reaches set temp, wide temperature swings, or won't shut off
• If the knob turns but temperature doesn't respond, the regulator may be faulty

• Disconnect electrical power before servicing; for gas models, also shut off the gas supply
• Access through the control area/back panel; note the original routing of the capillary tube and sensing bulb
• Handle the capillary tube carefully—do not kink or sharply bend; route and secure it in the original path and location
• Transfer the control knob and any mounting hardware from the old regulator if required, then verify proper shaft alignment before reassembly

Microwave not heating evenly or shutting off unexpectedly? This temperature sensor thermistor monitors cavity temperature and signals the control board.

The Support is an OEM part for Bosch microwaves. This part holds the microwave rack in place, allowing for multiple levels of cooking and ensuring the even distribution of heat. 

Causes of a bad rack support can include general wear and tear, exposure to high temperatures, or damage from heavy loads or accidental impacts. 

Symptoms of a bad microwave rack support include:

• Rack not staying in place
• Visible cracks or damage to the support
• Rack tilting or wobbling during use
• Decreased cooking efficiency or uneven cooking

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

Small bracket that holds and positions microwave components for proper alignment. Replace if cracked, broken, or missing to restore secure fit and reduce rattling.

Replacement cover that protects and finishes openings or components on your microwave. Shields internal parts from dust and moisture. Order if cracked or missing.

Replacement mounting washer that secures fasteners and distributes load to prevent wear and loosening. Essential for stable appliance assembly. Verify fit.

This replacement drive motor powers the wash drum in your machine, supplying the torque needed to tumble clothing and complete cycles under load. Replace a weak, seized, or noisy motor to restore smooth, reliable drum movement.

• Drives the drum/tub during wash and rinse cycles
• Common failure signs: drum won't turn/tumble or stops mid-cycle
• May hum, overheat, or emit a burning smell when failing
• Starts then stalls or trips the breaker on startup
• Some models may show a motor/drive-related error code

• Disconnect power before servicing; allow moving parts to stop completely
• Access the motor per your model (rear or bottom panel on most units)
• Label and disconnect wiring, remove mounting hardware, swap in the new motor
• Reassemble, ensure smooth drum rotation by hand, then run a test cycle

Fix unresponsive buttons or a cracked control panel. This console restores tactile button access and display openings. Moderate DIY repair for most users.

Fix intermittent power or control problems with this microwave cable harness. Restores secure electrical connections between components when wiring is damaged.

Replacement mounting screw for microwave panels, brackets, and internal components. Needed when original hardware is missing, stripped, or corroded.
