Bosch Microwave HMV8044U 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 power on? Replace a blown fuse that protects the electrical circuit from overloads. Simple fix restores power after resolving the cause.

Secures your microwave or internal assembly in proper position. Replace this bracket if bent, missing, or worn to restore stable, rattle-free alignment.

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.

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 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.

The microwave control unit contains the electronic circuitry that manages all microwave functions including power levels, timing, and safety features. Replace when the microwave won't start, stops mid-cycle, doesn't heat food, or when the display shows error messages.

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.

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

Replacement mounting nut for microwave installation. Secures panels, brackets, and hardware in place. Replace if original is missing, stripped, or worn.

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.

Replacement mounting screw for your microwave. Secures panels, brackets, and components to the frame. Replace stripped, corroded, or missing screws.

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.

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
