Parts for Kitchenaid KBMS1454RSS0: 03 - Door Parts

This door hinge assembly lets the appliance door pivot smoothly and hold proper alignment, restoring secure closing and preventing sag or gaps that can lead to cooling or sealing issues. What it does:

• Supports and guides the door as it opens and closes
• Keeps the door aligned to maintain an even seal and proper closing
• Helps stop door sagging, sticking, or uneven gaps
• Reduces rubbing or noisy movement at the hinge area

• Unplug the appliance or disconnect power before starting any repair
• Support the door while removing fasteners to avoid dropping or damaging the door
• Use appropriate hand tools and follow OEM torque recommendations when reassembling
• Check door alignment and seal after installation; adjust as needed

This door interlock assembly mounts behind the microwave's front panel and aligns the latch and safety switches. Replacing a worn interlock restores reliable door detection so the microwave only starts when the door is fully closed.

• Holds and actuates the internal door safety switches
• Maintains precise latch alignment to prevent false "door open" signals
• Ensures the microwave will not run with the door open for safety
• Common symptoms: won't start, requires pressing on the door to run, stops when the door is jostled, intermittent "door" message

• Disconnect power before servicing; microwaves contain a high-voltage capacitor that can retain a charge.
• Access typically requires removing the outer cabinet and control panel.
• Position switches correctly in the holder per your service manual and verify smooth latch engagement.
• After reassembly, the unit only operates with the door fully closed.

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. 

This release rod links the push-button to the latch mechanism so the microwave door opens when pressed. Replacing a bent or broken rod restores smooth, consistent door release and proper latch operation.

• Transfers motion from the door-open button to the latch levers to release the door catch
• Helps ensure the door opens promptly when the button is pressed
• Common symptoms: button does nothing or feels loose, door hard to open, intermittent opening
• Often fails due to wear, misalignment, or a dislodged linkage

• Disconnect power; microwaves contain a high-voltage capacitor that can retain a dangerous charge
• Remove the upper grille and control panel to access the latch/button linkage
• Note the rod's routing and any clips; transfer reusable hardware and match original orientation
• After reassembly, verify door switch alignment and test for smooth opening before use

This lower dishwasher spray arm circulates and directs pressurized water throughout the dishwasher basin to help clean dishes and cookware more evenly. Replacing a worn or damaged spray arm restores spray coverage and reduces spotting. What it does:

• Rotates and distributes water from the lower wash pump to reach bottom and mid-level racks
• Helps remove food soils and rinse away detergent residue for better cleaning results
• Worn, cracked, or clogged spray arms can cause poor cleaning, uneven results, or loud operation
• Compatible with standard lower spray arm mounts and spray patterns for many Whirlpool-style dishwashers

• One lower spray arm

• Disconnect power and water supply before starting any repair
• Remove the lower rack to access and replace the spray arm; hand-tighten retaining nut or clip per OEM guidance
• Inspect for retained debris or mineral buildup in the spray holes and clean before installation
• Do not overtighten plastic fasteners; test a short cycle to ensure proper rotation and no leaks

This support is a replacement mounting bracket that secures internal components and restores proper alignment and stability. It helps reduce vibration and prevents loose or sagging parts for safer, quieter operation. What it does:

• Provides a rigid mounting point to hold internal assemblies in place
• Restores correct alignment when panels or components sit unevenly
• Reduces vibration or rattling caused by a broken or missing support
• Helps prevent additional wear on adjoining parts by keeping components stable

• One support mounting bracket

• Recommended for repair by someone comfortable with appliance disassembly
• Disconnect power (and water, if applicable) before starting any repair
• Keep track of mounting hardware and gaskets removed during replacement
• Inspect adjacent parts for wear when installing this support and replace as needed

This tension spring restores proper movement and tension for the appliance component it secures, helping the part operate smoothly and reliably. It's a simple replacement that fixes common issues caused by worn or broken springs. What it does:

• Provides tension to hold or return a moving component to its correct position
• Helps stop sagging, slipping, or loose operation of doors, latches, or levers
• Can reduce rattling or unusual noises caused by a failed spring
• Restores normal mechanical action when the original spring is stretched or broken

• Disconnect power to the appliance before starting any repair
• Springs can be under tension—use appropriate tools and wear eye/hand protection
• Compare the new spring to the old one for length, coil size, and end fittings before installation
