Hmbr350 Parts

The Relay is an OEM part for use in Bosch microwaves. This part acts as a safety device, monitoring the temperature within the microwave to prevent overheating. If the microwave reaches an unsafe temperature, the relay thermostat will interrupt the power supply to the heating element or magnetron, effectively halting the cooking process to prevent damage or fire.

The need for replacement can arise from a thermostat that has become overly sensitive or has failed completely, often due to repeated exposure to high temperatures or in the event of a significant overheating incident.

Symptoms of a failing Relay include:

• The microwave unexpectedly turning off during use, especially if it hasn't been running long enough to complete the cooking cycle.
• The microwave refusing to start, which can occur if the thermostat is stuck in the open position, indicating an overheat condition even when the appliance is cool.
• Inconsistent cooking results, where the microwave seems to heat intermittently or not at all, suggesting the thermostat may be cutting off power prematurely.

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

A replacement door screen that restores the barrier at the appliance door opening and helps keep debris out of the door cavity. Fits into the door assembly to maintain proper airflow path and appearance. What it does:

• Provides a protective mesh/cover at the door to help block lint, crumbs and other debris from entering the door cavity
• Helps maintain the designed airflow path through the door opening for proper appliance operation
• Replaces torn, clogged or damaged screens that cause visible debris buildup at the door
• Reduces risk of small objects getting stuck in the door area and contacting internal components

• Disconnect power to the appliance before beginning any service
• Remove the door or inner door panel per the appliance service instructions to access the screen
• Handle the screen gently to avoid bending or damaging mounting tabs; use approved fasteners if required

This black dishwasher door liner restores the appliance's interior door surface and appearance after damage or wear. It provides a clean, finished look and supports the door's inner components for reliable operation. What it does:

• Replaces a cracked, dented, or discolored inner door panel to restore appearance
• Supports interior components and helps maintain proper door closure
• Reduces the chance of steam or water contacting insulation or electronics behind the liner
• Helps eliminate rattles or noise caused by a damaged liner

• Disconnect power and water supply before starting any repair
• Handle the door and any glass carefully; wear gloves and eye protection
• Removal typically requires loosening door screws and separating inner panels—follow the service manual

This microswitch is a small snap-action switch used to detect position and complete control circuits in appliances, restoring reliable on/off or closed/open signaling for door and actuator mechanisms. What it does:

• Acts as a position/limit switch to detect door or actuator positions and send the signal to the control board.
• Restores proper control-circuit continuity so cycles can start or finish when the door or part is in the correct position.
• Common symptom: appliance won't start, stops mid-cycle, or shows a door/lock fault when the switch fails.
• Small, mechanical switching action — responds to an actuator or lever movement.

• One microswitch.

• Disconnect power before accessing or replacing the switch to avoid shock or damage.
• Verify the exact switch location and actuator orientation before removal; note wiring placement or take a photo for reassembly.
• Test continuity with a multimeter only after safely isolating the appliance; replace if it fails to open/close reliably.
• May require partial disassembly of the control panel, door latch, or actuator housing; follow appliance-specific service instructions.

This small plastic clip secures internal components or wiring to the appliance chassis to prevent rubbing, movement, or noise. Replacing a worn or broken clip restores secure routing and reduces vibration-related sounds. What it does:

• Holds wiring harnesses or small parts in place to prevent chafing and wear
• Stops loose components from shifting during operation and causing rattles
• Helps maintain correct component alignment for reliable performance
• A broken or missing clip can allow wires or parts to contact moving pieces or hot surfaces

• Disconnect power to the appliance before starting any repair
• Clip typically presses into a matching slot or snaps over the component; no special tools usually required
• Handle small parts carefully; retain any removed fasteners for reuse
• If routing or mounting points are damaged, inspect surrounding parts for wear and replace as needed
