This lamp cover is the replacement lens that protects and diffuses your oven's interior light, restoring even illumination while keeping the bulb shielded from heat and food residue. It helps maintain safe, usable oven lighting. What it does:

• Protects the oven light bulb from splashes, crumbs and direct contact.
• Diffuses the bulb for more even interior illumination.
• Replaces a cracked, cloudy, melted or missing lens that can cause dim or exposed lighting.
• Fits over the lamp housing to restore the oven's normal light appearance and function.

• Disconnect power to the appliance before starting and allow the oven to cool completely.
• Handle the cover carefully—wear gloves to protect from sharp edges or broken glass.
• Remove any retaining screws or clips, swap the old cover for the new one, then secure the retainer.
• After installation, restore power and replace the bulb if issues persist.

The 40W Light Bulb is an OEM replacement part for Whirlpool microwave ovens. It is a standard-size bulb designed to provide illumination inside the microwave cavity, allowing you to easily view and monitor the cooking or reheating process.

Symptoms of a faulty microwave light bulb include:

• Dimming or flickering light during operation
• Complete bulb failure or no illumination within the cavity
• Discoloration or physical damage to the bulb itself

Causes of a bad microwave light bulb can include normal wear and tear over time, electrical surges or voltage fluctuations, or physical impact or vibration during use.

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

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

The Charcoal Filter is an OEM replacement part for Whirlpool microwaves. Containing activated charcoal fibers, this filter eliminates odors from foods being cooked inside the microwave.

Causes can be the natural saturation of the charcoal after extended use cycles. The material reaches its adsorption capacity.

Symptoms of a bad charcoal filter include:

• Lingering food smells within the microwave interior
• Odors transferring to other foods during subsequent reheating
• Decreased ability to absorb offensive smells over time

This is a genuine Whirlpool OEM replacement this part is also compatible with Maytag, Jenn-Air and some Kenmore models.

This thermostat is a temperature cutoff switch for the microwave magnetron that helps stop the magnetron if it overheats, protecting the component and preventing further damage. Fits in the oven cavity thermal assembly. What it does:

• Senses magnetron or cavity temperature and opens the circuit when temperatures exceed safe limits
• Helps prevent magnetron overheating that can cause loss of heating or smoke
• Can cause the microwave to shut off or stop heating when the thermostat trips
• Works as part of the oven's thermal protection system, not a user control

• One magnetron thermostat

• Disconnect power and ensure the high-voltage capacitor is fully discharged before servicing
• Access requires removing the microwave oven cabinet; follow OEM service manual guidance
• Replace only with the correct part number; improper installation can create shock or fire hazards

This is a thermal safety fuse that opens the circuit if temperatures rise beyond a safe limit, protecting the appliance from overheating and preventing further damage. Replacing a failed fuse restores power to the affected circuit once the underlying cause is addressed.

• Monitors temperature in a protected circuit and cuts power if unsafe heat is detected
• Helps prevent overheating-related damage
• Typical failure signs: no power/no operation, cycle won't start, shuts off mid-cycle after overheating event
• Must not be bypassed; replace if open and investigate the root cause of overheating

• Unplug appliance or disconnect power before service
• Verify the fuse is open with a multimeter; replace only after correcting any airflow/overheating issues
• Install in the same orientation and location as the original to ensure proper temperature sensing
• Handle wiring carefully; transfer connectors one at a time to avoid miswiring

This replaceable refrigerator water filter cartridge helps restore clear, better-tasting drinking water and ice by capturing sediment and common impurities. Designed for a quick swap to keep your fridge dispensing clean water. What it does:

• Filters sediment and particulate to reduce cloudiness in water and ice
• Helps improve taste and odor commonly associated with older filters
• Restores normal water flow and delivery when a clogged filter causes slow dispensing
• Supports routine maintenance to help prevent scale and buildup in the dispenser system

• Shut off the refrigerator water supply before removal to limit spills
• Follow the refrigerator manufacturer's removal/installation motion (push, pull, twist, or bayonet style)
• Flush several full glasses of water after installation to clear air and initial carbon fines
• Check for leaks at the filter and housing after restoring the water supply; discard the old filter per local regulations

• The microwave failing to power on or having intermittent power
• Food not heating up properly or unevenly
• Strange sounds like buzzing or humming emanating from inside
• The door lock mechanism not engaging or release properly
• Repeated tripping of fuses or circuit breakers

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