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.

The Lint Screen Housing Foam Seal is an OEM part for Whirlpool dryers. This seal is placed around the lint screen housing to prevent air leaks and ensure that the dryer operates efficiently by directing airflow properly through the lint screen. By maintaining a tight seal, this foam helps to optimize the dryer’s performance, reduce drying times, and prevent lint from escaping into the internal parts of the dryer, which can lead to potential maintenance issues and decreased efficiency.

Symptoms of a failing lint screen housing foam seal include:

• Increased lint buildup inside the dryer beyond the lint screen
• Longer drying times due to inefficient air circulation
• Excessive heat and humidity within the dryer

Causes of foam seal deterioration typically involve normal wear and tear, exposure to high heat which can degrade the material, or improper maintenance that can tear or dislodge the foam.

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

This primary door interlock switch lets the microwave know the door is fully closed so cooking can start. Replacing a worn or sticking switch restores reliable start/stop response and helps prevent intermittent operation tied to door-latch signaling. What it does

• Confirms the door is closed to allow the control to power the cook circuit
• Common symptoms of a failed switch: won't start, stops when the door is jostled, or only runs when pressing on the door
• Installs on the latch/door switch bracket alongside secondary/monitor switches
• Helps correct inconsistent or no response when pressing Start

• One primary door interlock switch

• Disconnect power at the breaker; microwaves contain high-voltage components that can retain a dangerous charge
• Access the latch/switch bracket, then release the switch from its clip or screws
• Move wires to the same terminals on the new switch; match orientation/actuator position
• After reassembly, verify the unit does not run with the door open and starts consistently with the door closed

Ceramic

This wafer head screw secures panels, brackets, and other components inside your appliance. Replacing worn or missing hardware restores a tight fit, reduces vibration and rattles, and keeps assemblies properly aligned for reliable performance.

• Fastens panels, brackets, or trim with a low-profile wafer head for even clamping
• Replaces stripped, corroded, or missing hardware (#8 x 3/8)
• Helps maintain alignment and reduce vibration or rattling noises
• Restores secure mounting for safe, stable operation

• Disconnect power; also shut off gas before servicing
• Support the panel or component while removing/installing hardware
• Hand-start threads to avoid cross-threading; tighten snugly without overtightening
• Replace screws one at a time to maintain alignment

This high temperature limit switch monitors dryer air temperature and stops the heater if temperatures exceed safe levels, preventing overheating and helping protect the dryer and clothes from heat damage. What it does:

• Senses excessive dryer temperature and opens the heating circuit to stop the heater from running
• Helps prevent overheating, burning smells, or fabric scorching linked to high-heat conditions
• Works as a safety cutoff when other thermostats or air flow controls fail
• Commonly used in electric dryer heater assemblies

• One high temperature limit switch

• Disconnect power before servicing to avoid shock or electrocution
• Install in the same orientation and wiring positions as the original; secure mounting is required for proper temperature sensing
• Inspect venting and heating components when replacing; replace any damaged wiring or connectors

This wafer-head Phillips screw (#8 x 3/8 in) is a factory fastener used to secure panels, brackets, and covers in compatible appliances. Replace a missing or damaged screw to restore a tight, properly aligned fit. What it does:

• Secures sheet-metal or plastic components to the appliance chassis or subassemblies
• Helps maintain proper alignment and reduce vibration or rattling
• Replaces lost, stripped, or corroded screws of the same size and type
• Used at panel, bracket, and cover mounting points designed for this fastener

• One wafer-head Phillips screw (#8 x 3/8 in)

• Disconnect power (and gas, if applicable) before servicing
• Start threads by hand to avoid cross-threading; use a #2 Phillips driver
• Do not overtighten, especially into plastic or thin sheet metal
• Replace only with the same size/type fastener removed to ensure proper fit

This fuse block is the appliance electrical terminal used to secure and connect a fuse or wire harness, restoring a safe electrical path for heating and motor circuits. It helps maintain reliable power transfer inside the appliance. What it does:

• Provides a secure mounting point and electrical connection for a fuse or inline connection
• Enables proper power flow between the control and high-voltage components
• Can cause loss of power, intermittent operation, or heating issues when damaged or corroded
• Replaces a worn, cracked, or melted terminal block to restore safe connections

• Disconnect power to the appliance before starting any work
• Handle wiring carefully; secure all splices and fasteners to manufacturer torque recommendations

This service bushing protects and cushions appliance wiring where it passes through metal panels, helping prevent chafing and shorts. It's a simple replacement that restores proper routing and insulation for harness wires. What it does:

• Cushions wiring at panel openings to reduce abrasion and wear
• Keeps wiring properly routed to prevent pinching or intermittent connections
• Helps stop rattling or vibration where wires contact metal edges
• Addresses symptoms like exposed or frayed insulation, burning smell, or intermittent power related to damaged panel wiring

• One service bushing

• Disconnect power before starting any repair
• Remove the access panel or trim to reach the damaged bushing location
• Press the bushing into the panel hole until fully seated; replace wiring through the bushing as routed originally
• Inspect surrounding wiring and replace any frayed or heat-damaged sections; reassemble panels securely
