Bosch Microwave HMC80242UC Parts

This small electric motor drives the turntable plate inside the microwave, rotating food for even heating during cooking. It connects to the turntable coupler beneath the glass tray. Replace this motor if the turntable stops rotating, turns intermittently, or makes grinding or humming noises without spinning.

This plastic-foil capacitor is used in the appliance's electrical circuit to provide stable capacitance. It supports proper motor and power-circuit operation, helping components start and run smoothly while minimizing electrical noise. What it does:

• Stores and releases electrical energy to support motor starting/running or stabilize the power circuit
• Helps reduce electrical noise and voltage spikes in the system
• A failing capacitor can cause hard starting, humming, weak or intermittent operation, or tripped breakers
• Visible bulging, cracks, or heat damage on the capacitor indicates replacement is needed

• 1 capacitor

• Disconnect power at the breaker before servicing; verify no power is present
• Capacitors can retain a charge—discharge safely using appropriate tools and procedures
• Note wire positions and terminal orientation; transfer one lead at a time or take a reference photo
• Mount securely and keep wiring clear of sharp edges, heat sources, and moving parts

Holds the bulb and provides electrical connection for interior lighting. Replace if cracked, heat-damaged, or loose causing lights to fail. Confirm fit.

Microwave won't heat but powers on? Replace the high voltage transformer. Also fixes loud humming or blown fuses. Moderate difficulty repair part.

Temperature regulator that monitors and controls an appliance's operating temperature to help maintain set points and stable performance. Replacing a faulty regulator can restore consistent temperature behavior and reliable operation. What it does:

• Senses and regulates temperature to maintain the appliance's set point.
• Signals the appliance's heating or cooling system to cycle on and off as needed.
• Common symptom: appliance temperature is too high or too low.
• Common symptom: temperature fluctuates or fails to stabilize.
• Common symptom: heating/cooling runs continuously or not at all.

• Disconnect power to the appliance before starting any service.
• Handle electrical connections and terminals with care; note wire locations before removal.
• Follow the appliance service manual or wiring diagram for proper placement and orientation.

This replacement screw secures appliance panels and components at their mounting points. Swap in a new screw to restore a tight, rattle-free fit when the original fastener is missing, stripped, or corroded.

• Fastens the designated panel, bracket, or component in place
• Replaces a missing, stripped, or rusted screw
• Helps address loose panels, gaps, rattling, or misalignment at the mounting point
• Maintains proper assembly integrity after service or vibration

• Disconnect power; shut off water supply if working near plumbing
• Match to the removed fastener and replace one at a time to preserve alignment
• Start threads by hand to avoid cross-threading; use the correct driver bit
• Tighten snugly and avoid overtightening, especially into plastic or thin sheet metal

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

Conditions incoming AC power and suppresses electrical interference to protect electronics. Replace if your microwave won't start or behaves erratically.

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

Replacement interior light bulb that illuminates your microwave or oven cavity for visibility while cooking. Replace when bulb burns out or dims. Verify fit with your model number before ordering.

Glass turntable tray that rotates food inside your microwave. Replace if cracked, broken, or missing to restore safe, level support for dishes.

Microwave won't heat in convection mode? This circular heating element surrounds the fan and restores fast, even baking. Moderate DIY repair.

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

Fix a microwave that won't power on or respond to controls with this cable harness. Restores electrical connectivity between control board and components.

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

Secures panels, brackets, and components inside your microwave or wall oven. Replace missing, rusted, or stripped screws to restore proper fit.
