Parts for Kitchenaid KHMS2056SBL3: 04 - Interior & Airflow Parts

This thermistor is a temperature-sensing component mounted near the magnetron in the microwave. It monitors the magnetron's temperature and signals the control board to shut off the magnetron if it overheats. Replace this part if the microwave stops heating intermittently, shuts off unexpectedly during use, or displays an error code related to overheating.

Microwave not heating? This magnetron generates microwaves to heat food. Replacing a faulty magnetron restores heating and stops cooking failures.

If your microwave door won't latch or close properly, this door latch piston may be worn or broken. Simple DIY fix restores proper door operation.

This cam plate is the stamped metal guide that secures and locates the dryer drum, helping maintain smooth rotation and proper alignment. Replaces a worn or damaged cam that can cause noise, rubbing, or uneven drum movement. What it does:

• Positions and guides the dryer drum to prevent lateral movement and maintain alignment.
• Absorbs and transfers load between the drum and the rear support assembly for stable rotation.
• Reduces metal-on-metal contact that can cause squeaks, scraping, or worn drum edges.
• Helps restore smooth drum tracking when a broken or worn cam causes rubbing or off-center rotation.

• One cam plate

• Disconnect power before starting any repair to prevent shock or injury.
• Access typically requires removing the dryer front or top panel and supporting the drum; follow OEM service manual steps.
• Inspect associated rollers, glides, and mounting hardware and replace if worn to prevent repeat failure.
• Tighten fasteners to OEM torque and verify proper drum rotation before full reassembly.

Microwave won't heat or shows F1E5 error? The inverter regulates power to the magnetron. Intermediate repair, 1-2 hours with full disassembly required.

Prevents magnetron overheating in your microwave. This cavity over-temperature thermostat shuts off power when temperatures exceed safe limits.

This interlock is the door latch assembly that keeps a dryer door closed and prevents the dryer from running when the door is open. It restores proper door sensing for safe, reliable operation. What it does:

• Secures the dryer door so the machine only runs with the door fully closed
• Activates the door-safety circuit so the dryer stops when the door opens
• Commonly replaced when the door won't latch or the dryer won't start
• Helps eliminate intermittent start/no-start symptoms related to door sensing

• One interlock assembly

• Disconnect power before starting any repair to avoid electrical shock
• Replace only with the exact part number specified for your model
• Basic hand tools are typically required; avoid forcing plastic clips and connectors

The Switch is an OEM part for Whirlpool microwaves. It controls the turning on and off of power to the microwave during cooking cycles as well as detects positions within cycles to signal appropriate actuations of the microwave's magnetron, fans, and lights. The switch is a crucial electrical component that facilitates the fully automatic operation of preset cooking programs.  

Causes of a bad switch can include wear and tear over time or unexpected surges that cause electrical component failure.

Symptoms of a bad switch include:

• Cooking programs failing to advance properly or stopping mid-cycle unexpectedly
• The microwave failing to turn on or experiencing power issues  
• Random noises, humming, or lights occurring when the microwave is supposed to be idle
• Buttons or controls acting intermittently unresponsive

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances. 

Microwave has no power or won't heat? A blown thermal fuse is often the cause. This safety part protects against overheating. DIY repair in 30 minutes.

Microwave displays 'close door' message or won't start? The door interlock switch is likely failed. Moderate DIY repair—replace all 3 switches together.

This door interlock switch is a safety micro switch that detects whether the microwave door is properly closed before allowing the unit to operate. It is a small, snap-action switch mounted near the door latch mechanism. Replace this switch if the microwave won't start, runs with the door open, or blows a fuse when the door is closed.

This assembly combines a humidity sensor and thermostat used in over-the-range microwaves to detect moisture and temperature levels during cooking. The humidity sensor enables auto-cook and auto-reheat features by sensing steam released from food, while the thermostat monitors internal temperature for safety. Replace this part if your microwave no longer accurately auto-cooks or auto-reheats food, runs too long or shuts off too early, or if you get error codes related to sensor functions.

This is a plastic support bracket that holds the door interlock switch in the correct position inside the microwave. It ensures the safety switches align properly with the door latch mechanism so the microwave only operates when the door is fully closed. Replace this bracket if your microwave fails to start, runs with the door open, or if the interlock switch is misaligned or loose.

Secures microwave components in place during operation. Replace if broken, loose, or missing to prevent rattling and ensure proper assembly. Verify fit with your model number.

This is a small incandescent surface light bulb used inside the microwave to illuminate the cooking cavity. It provides visibility so you can monitor food while it cooks. Replace this bulb if the interior light no longer turns on or flickers intermittently.

The lamp housing holds and protects the oven's interior light bulb, typically mounted on the oven cavity wall or ceiling. Replace when the housing is cracked, melted, or the light flickers despite a good bulb.
