Parts for Bosch HMC87151UC/01: Convection Parts

This circular heating element sits around the oven's convection fan and supplies the heat used in convection modes. Replacing a failed ring heater restores fast, even convection baking and consistent temperature control. What it does:

• Provides the primary heat source for convection bake/roast by surrounding the fan
• Helps maintain even temperature and airflow during convection cycles
• Common fix when convection mode won't heat or preheats slowly
• Replace if the element is open, blistered, or visibly broken

• One ring-style convection heating element

• Disconnect power to the oven/range before servicing
• Access is typically from the rear or by removing the interior fan cover; note wire positions before removal
• Avoid bending the element; transfer any brackets as required and secure mounting screws
• Reconnect wires firmly and test operation before reinstalling panels

This genuine screw secures panels, brackets, and other components in your appliance. Replacing a missing, rusted, or stripped fastener restores a snug fit, reduces vibration, and helps keep assemblies properly aligned during daily use.

• Fastens panels, brackets, or covers to the appliance chassis
• Helps maintain alignment to reduce looseness and vibration
• Replaces missing, corroded, or stripped hardware

• Disconnect power and shut off water/gas before servicing
• Support the panel or component while removing the damaged screw
• Start the new screw by hand to avoid cross-threading, then tighten until snug—do not overtighten
• If the receiving clip or hole is stripped, repair or replace that hardware before reinstalling

This is a replacement mounting nut used to secure components on compatible Bosch appliances. It restores proper fastening to reduce movement and noise from loose connections. What it does:

• Secures panels, assemblies or brackets to prevent shifting during operation
• Restores proper clamp force where a stripped or missing nut causes looseness
• Helps eliminate rattling or vibration caused by unsecured parts
• Provides a direct replacement for the original fastener

• Turn off and unplug the appliance or shut off power at the breaker before servicing
• Use the correct-size wrench or socket to avoid rounding the nut
• Tighten to a snug fit; avoid over-tightening which can strip threads or damage parts

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

The Thermistor is an OEM part for Bosch microwaves. This part is responsible for monitoring and regulating the temperature inside the microwave cavity during operation. It measures the temperature and sends signals to the control board, allowing the microwave to adjust its power output accordingly.

A bad thermistor can occur due to damage, electrical malfunctions, or temperature sensor failure. Signs of a faulty thermistor include inconsistent heating, overcooked or undercooked food, or error messages displayed on the microwave's control panel.

Symptoms of a bad thermistor include:

• Inconsistent heating  
• Error messages displayed

Replace your malfunctioning or damaged microwave thermistor with this genuine OEM Bosch part to restore your microwave. This Bosch part can also be used on Thermador and Gaggenau appliances.
