The Nut is an OEM part for Whirlpool microwaves. It helps secure various parts within the microwave, ensuring proper assembly and function. It is used to fasten items, keeping them securely in place during use.

A bad microwave nut can occur due to wear and tear over time or accidental damage. If the nut becomes loose, stripped, or misplaced, it can lead to instability and compromise affected parts.

Symptoms of a bad microwave nut include:

• Loose or wobbly parts.
• Difficulty in operating the microwave.
• Unusual noises or vibrations during use.

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

Comes with 4 supports. Color: chrome.

This support secures and stabilizes a mating component inside your appliance, helping restore proper alignment and fit. Replace a damaged or missing support to stop wobble, sagging, or misalignment.

• Provides structural backing to keep the attached part level and in place
• Helps eliminate rattling, shifting, or uneven gaps
• Replace if cracked, deformed, or missing
• Symptoms can include loose or sagging parts, poor alignment, or difficulty reinstalling shelves/panels

• Disconnect power (and shut off water, if applicable) before service
• Remove the affected shelf/drawer/panel to access the support
• Transfer and reuse any model-specific fasteners or clips
• Seat the new support fully and check alignment before reassembly

This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

• Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
• Prevents unstable magnetron operation that can cause weak or no heating.
• Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
• A failed capacitor can also cause blown internal fuses or tripped circuits.

• One capacitor.

• Disconnect power and verify the appliance is completely de-energized before servicing.
• Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
• Use the exact replacement part and follow the appliance service manual for routing and connections.

The Screw is an OEM part for Whirlpool microwaves. It is responsible for securing various parts of the microwave together. This screw ensures a tight and secure fit for parts and helps maintain the structural integrity of the microwave, preventing any loose or rattling parts.

A bad microwave screw can occur due to wear and tear, accidental damage, or misplacement during maintenance or repairs. If you notice symptoms such as loose or wobbly components, difficulty in opening or closing the microwave door, or abnormal noises while the microwave is in use, it may be time to replace this part.

Symptoms of a bad microwave screw include:

• Loose or wobbly components
• Difficulty in opening or closing the microwave door
• Abnormal noises during operation

Restore your Whirlpool microwave by replacing the faulty or missing microwave screw with this genuine OEM part.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
 

This electrical safety fuse opens the circuit when a short or overcurrent occurs. Replacing a blown fuse can help restore power after the root cause is corrected, protecting controls and wiring from further damage.

• Protects the appliance by interrupting power during overcurrent or short-circuit events
• When open/blown, the appliance may be completely unresponsive
• Helps prevent damage to control boards and wiring during faults
• Often fails after a component shorts or a power surge occurs

• Disconnect power to the appliance before servicing
• Use a multimeter to test the fuse for continuity; replace only if open
• Install a fuse with the exact same rating and form factor as the original
• If the new fuse blows again, stop and diagnose the underlying fault; consider service for high-voltage systems

This microwave magnetron is the high-voltage tube that generates the microwave energy to heat food. When it fails, the oven may run but not heat or heat very slowly. Replacing it restores normal cooking performance. What it does:

• Produces the microwave energy that heats food in the oven cavity
• A failed unit can cause the microwave to run but not heat
• Can create an unusual loud humming or buzzing during operation

• Includes 1 magnetron

• Unplug the microwave and discharge the high-voltage capacitor before servicing
• Handle by the mounting surfaces; avoid touching or damaging the antenna and ceramic insulators
• Reconnect high-voltage leads exactly as routed and reassemble cooling airflow parts; test with a cup of water to confirm heat

This support is a factory mounting piece that secures and aligns its mating component inside the appliance. Replacing a worn or broken support restores proper fit, stability, and smooth operation of the associated assembly.

• Provides structural support and accurate positioning for the designated part
• Helps prevent sagging, looseness, and vibration
• Maintains alignment so components latch/seat correctly
• Typical failure signs: cracked or missing support, rattling, misalignment, or parts that won't stay in place

• Disconnect power before servicing; also shut off the water supply
• Note the original orientation; transfer any screws, clips, or spacers from the old support
• Install without overtightening to avoid damage; secure fit of the supported component after installation

Color: black. Measures about 11 inches wide by 2-1/2 inches high.

This factory support stabilizes and positions its mating assembly so it stays secure and aligned during use. Replacing a worn or broken support helps restore proper fit and prevents looseness or shifting that can affect performance. What it does

• Provides structural support and correct positioning for the related assembly
• Helps prevent wobble, sagging, rattling, or misalignment
• Typical failure signs: visible cracks, broken/missing tabs, or a loose fit
• Can help resolve components not staying in place or moving unexpectedly

• 1 support

• Disconnect power to the appliance before servicing
• Access the support location and note the original orientation
• Transfer and reuse any original mounting hardware your model uses
• Seat the new support fully and verify a secure fit before restoring power

This stirrer cover rivet secures the microwave's stirrer cover in the ceiling of the oven cavity. A snug, intact cover helps protect the stirrer mechanism from splatters and keeps it properly positioned for consistent heating.

• Holds the stirrer cover firmly in place inside the cavity
• Helps prevent rattling noises from a loose or missing cover
• Can address issues like a sagging or fallen stirrer cover
• Replacing damaged or missing rivets supports even cooking performance

• Disconnect power to the microwave before servicing
• Access the interior cavity; support the cover while installing the rivet
• Insert through the cover and mounting hole; seat fully so the cover is secure
• Microwaves contain high-voltage components.

This Light Housing secures and protects the interior lamp assembly, helping keep the compartment safely illuminated. Replace a cracked or heat-damaged housing to restore a stable bulb fit and consistent lighting performance. What it does:

• Provides a stable mount for the interior light bulb/socket
• Shields nearby wiring and components around the lamp area
• Helps position the light for proper illumination inside the compartment
• Common signs of wear: cracked or melted housing, loose bulb fit, lens/cover won't stay attached, intermittent lighting from a poor physical connection

• 1 light housing

• Disconnect power to the appliance before servicing
• Remove the lens/cover and bulb, then unfasten the damaged housing
• Transfer the existing socket, wiring, and any hardware from the old housing as needed
• Reinstall the housing, replace bulb/cover, restore power, and test the light
