Parts for Whirlpool MH1141XMB0: 04 - Air Flow Parts

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 is a genuine replacement screw used to fasten appliance panels, trim, and components. It restores secure attachment and helps eliminate rattles or loose parts for safe, reliable operation. What it does:

• Secures panels, brackets, trim pieces, or internal components
• Stops vibration-related noise caused by loose or missing fasteners
• Restores proper alignment and fit of assembled parts
• Provides the correct thread and length for the intended factory location

• One screw

• Use the correct screwdriver or bit to avoid stripping the head
• Hand-start the screw to ensure correct thread engagement before final tightening
• Tighten until snug; avoid over-tightening which can strip threads or crack plastic
• Disconnect power to the appliance before working in areas near electrical components

This lamp holder, also called a light socket, secures the bulb and provides the electrical connection so the appliance light works reliably. Replace a heat-damaged or loose socket to restore steady illumination.

• Allow the area to cool and handle glass bulbs with care
• Transfer wires to the new holder one at a time to maintain correct connections
