Parts for Bosch HMV8052U/01: Magnetron Parts

This is a door latch assembly that also serves as the switch holder in a microwave. It engages the door switches when the door is closed, ensuring the microwave operates safely and only when properly sealed. Replace this part if the microwave door won't latch securely, the unit fails to start, or the door switches are not activating correctly.

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

This lever is part of the door lock/latch mechanism. It engages with the latch to allow the door to lock and unlock smoothly, helping the appliance start and run only when the door is securely closed.

• Transfers motion from the handle/lock assembly to engage or release the latch
• Worn or broken levers can cause the door not to latch, not start, or show door-closed errors
• Cause difficulty opening/closing or a loose handle feel when faulty

• Disconnect power and shut off water before servicing
• Access is typically from the inner door panel; retain original screws and clips
• Note the lever's orientation and linkage points before removal
• Test door operation and cycle start after reassembly

The Switch is an OEM part for Bosch microwaves. It plays a role in the safety and functionality of the microwave, acting as a security mechanism that prevents the microwave from operating when the door is open. This ensures that microwave radiation is contained and only in use when the door is securely closed, protecting users from accidental exposure.

Causes of a malfunctioning door switch can range from physical damage, such as cracks or wear from repeated use, to electrical issues like short circuits or disconnections.  

Symptoms of a bad Microwave Door Switch include:

• The microwave fails to start or stops unexpectedly.
• The interior light fails to turn on or off appropriately.
• Unusual sounds when the door is opened or closed.
• The microwave operates only when the door is in a certain position or not at all.

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

The Microwave Switch is an OEM part for Bosch microwaves. It functions as a safety device that ensures the microwave operates only when the door is securely closed.

You should replace this microwave switch if it becomes faulty due to wear and tear, or if it's damaged from electrical issues or physical impact. A malfunctioning switch can prevent the microwave from starting, cause it to stop unexpectedly, or lead to safety hazards by allowing the microwave to run with the door open.

Symptoms of a bad microwave switch include:

• Microwave not starting
• Intermittent operation or shutting off unexpectedly
• Microwave running with the door open
• Error codes related to door or safety switches

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

This temperature regulator is the thermostat control that helps maintain the correct interior temperature by cycling the cooling system on and off. It replaces a failed regulator to restore steady temperature control and reduce temperature swings. What it does:

• Senses and regulates appliance temperature to keep the compartment within set range
• Cycles the compressor or cooling components to maintain consistent cooling
• Commonly used when interior temperature is too warm, fluctuating, or compressor runs continuously
• Works with the appliance's control system to trigger cooling actions as needed

• Disconnect power before servicing to avoid shock or damage
• Handle the sensor and terminals carefully; avoid bending or stressing the connector
• Verify correct orientation and secure mounting; confirm electrical connector is fully seated

Microwave not heating food? The magnetron generates microwave energy for cooking. This repair requires electrical safety knowledge and proper discharge.

Replacement mounting screw for microwave ovens. Secures panels, brackets, and internal components. Needed when original fasteners are lost or stripped.

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

This high-voltage transformer delivers the elevated voltage pulses used by the appliance ignition system to produce sparks for burner ignition. It replaces a failed transformer to restore reliable spark generation and ignition performance. What it does

• Steps up voltage to the ignition/igniter circuit so sparks form at the burner or igniter
• Common symptom: no spark or weak/intermittent sparking during attempted ignition
• Can help resolve ignition failure or repeated relighting when the transformer is the faulty component
• Works as the electrical source for spark modules or igniters in compatible appliance models

• One high-voltage transformer

• Turn off electrical power and gas supply before starting any service
• Handle and test high-voltage components cautiously; avoid contact with terminals when powered

This temperature regulator is the replacement control component that helps maintain proper temperature regulation in your appliance, restoring consistent heating or cooling performance when the original regulator fails. What it does:

• Senses and regulates temperature input to the appliance control system to maintain set temperatures
• Can cause inaccurate temperatures, inconsistent cycling, or failure to heat/cool when worn or faulty
• Replaces a failed or intermittent regulator to restore normal temperature control behavior
• Works as part of the appliance's thermal control circuit

• Disconnect power to the appliance before attempting any service to avoid shock or damage
• Handle the part by its housing; avoid touching electrical contacts or circuit traces
• Basic tools may be required; follow the appliance service manual for access and mounting steps

The Temperature Regulator is an OEM replacement part for Bosch microwaves. It plays a crucial role as an electronic interface governing set temperatures and interior heating levels. Consistent and calibrated regulation is necessary for safe and evenly cooked meals. 

Causes of a bad temperature regulator can include normal wear from continual heating cycles. Water damage from condensation or spills has the potential to impact electrical components.

Symptoms of a bad temperature regulator include:

• Inaccurate or fluctuating interior heat, causing cold or hot spots 
• Temperature settings that do not correspond to actual conditions
• Failure to properly increase or decrease power as programmed
• Sensor malfunctions requiring foods to be under or overcooked 

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models. Replacing it ensures continued precise temperature control and safe, reliable microwave operation.

Mounting screw for microwave installation and assembly. Replaces lost, stripped, or damaged screws that secure panels, brackets, or components.

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

Microwave not heating food evenly or at all? A failed diode disrupts power flow to the magnetron. This electronic component regulates electricity flow.

Microwave won't power on? Replace a blown fuse that protects the electrical circuit from overloads. Simple fix restores power after resolving the cause.
