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 factory screw secures appliance components to their mounting points. Replace missing, worn, or stripped hardware to restore a tight fit, proper alignment, and quieter operation across the affected assembly.

• Fastens panels, brackets, covers, or internal parts to the chassis or frame
• Helps maintain alignment and support, reducing rattle, vibration, or looseness
• Replaces missing or damaged screws that have backed out, broken, or stripped
• Restores secure mounting after service when original hardware is lost

• Disconnect power; shut off water or gas supplies before servicing
• Use the correct driver; start threads by hand to avoid cross-threading
• Match length and thread to the original location; do not substitute with longer hardware
• Tighten snugly; do not overtighten into plastic or thin metal

This 15 amp, 250 volt replacement fuse protects your appliance's electrical circuits by interrupting power when a fault or overload occurs. It restores safe operation once the underlying issue is fixed and the fuse is replaced. What it does:

• Acts as an overcurrent protection device for circuits rated up to 15 A and 250 V
• Prevents damage to wiring and components by opening the circuit during an overload or short
• Common symptom: appliance has no power or specific functions stop working after a sudden failure
• Replacing a blown fuse can resolve intermittent power loss or complete power failure tied to a single blown element

• Disconnect power to the appliance before inspecting or replacing the fuse
• Replace only with a fuse of the same amperage and voltage rating to maintain safety and proper protection
• Use insulated tools and avoid touching live terminals; internal access may require disassembly, follow OEM service instructions
• If fuses blow repeatedly, stop using the appliance.
