Bosch Microwave HMV3051C Parts

Structural support frame that holds and aligns components inside your microwave. Replace if cracked, warped, or damaged to restore proper fitment.

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.

Replacement electrical fuse that protects the appliance's control circuits from overloads and short circuits. Installing a correct replacement fuse restores circuit protection and can allow the appliance to power up normally after a blown fuse. What it does:

• Protects control and power circuits by opening when excess current or a short occurs.
• Common symptom: appliance is completely dead or the control panel is unresponsive.
• Also used when intermittent power or repeated tripping indicates a failed circuit protector.
• Keeps a failed circuit isolated to help prevent further damage to the control board or wiring.

• Always disconnect power at the breaker or unplug the appliance before inspecting or replacing the fuse.
• Verify the part number and electrical rating on the old fuse matches the replacement; replace only with an identical-rated fuse.
• Test the old fuse for continuity with a multimeter to confirm failure before replacing.

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

Protective housing cover that shields internal microwave components. Replacement for cracked, broken, or missing covers that expose sensitive parts.

If your microwave won't heat or runs but food stays cold, a failed rectifier diode may be blocking power to the magnetron. This replacement restores heating.

A replacement circulation pump motor that restores water movement in the dishwasher's wash system for proper cleaning and rinsing. Installs in the pump assembly to replace a worn or failed motor and stop noisy or non-operating pumps. What it does:

• Drives the dishwasher's water circulation/pump assembly so wash arms receive proper water flow.
• Common symptom: little or no water spray during the wash cycle or poor cleaning performance.
• Common symptom: loud grinding, humming, or the pump not starting when the cycle runs.
• Works as the rotating motor portion of the pump; requires correct pump housing and seals for a leak-free installation.

• One motor

• Disconnect power and turn off water supply before beginning repair.
• Inspect pump housing, gaskets, and impeller during replacement; replace worn seals to prevent leaks.
• Handle the motor and electrical connections carefully; ensure connectors are fully seated and secured.
• After installation, restore power and run a short cycle to check for proper operation and leaks.

Microwave not heating? The magnetron tube generates the microwave energy needed to heat food. Requires electrical knowledge to replace safely.

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

This replacement spring restores the proper tension and return action for the mechanism it serves in your appliance. It helps moving parts operate smoothly and reset reliably so doors, levers, or linkages stay aligned and feel correct. What it does:

• Provides controlled tension so doors, flaps, levers, or linkages move and return to position correctly
• Helps maintain alignment and consistent feel of the mechanism
• Typical failure signs: weak or broken return, sticking/sluggish movement, parts that won't stay in position, or unusual popping noises
• Visible distortion, rust, or a missing spring indicates replacement is needed

• Includes 1 spring

• Disconnect power (and water, if applicable) before servicing; wear gloves and eye protection
• Springs store energy—release and install with care, keeping fingers clear
• Note original routing/orientation; take photos to match placement during reassembly
• Use needle-nose pliers or a hook tool for control; replace paired springs together if your model uses two

Protective cover that shields internal microwave components from debris and contact. Replace when cracked, warped, or missing to restore proper enclosure.

Fix a microwave that won't start or heat properly with this high voltage capacitor. Restores proper electrical performance to the control circuit.

This is an electrical noise filter module that mounts inside the microwave cabinet. It filters out electromagnetic interference generated by the microwave's components to prevent disruption to other nearby electronics. Replace this part if the microwave trips a breaker, fails to start, or causes interference with other appliances.

If your microwave won't start, has unresponsive buttons, or loses power intermittently, this main control board restores electronic command and timing functions.

Fix a microwave that won't turn or makes grinding noises with this drive coupling. Connects motor to gearcase to restore proper turntable rotation.

Metal mounting bracket for microwave installation. Secures microwave to wall or cabinet. Replace if bent, cracked, or missing for proper support.
