AMI PARTS 8206232A Bulb – 40W 125V, E17

The AMI PARTS 8206232A bulb is a standard 40-watt, 125-volt, E17-base lamp designed for microwave interior lighting. It is non-dimmable and made of glass, with straightforward screw-in installation. Models commonly supported include a broad spectrum of Whirlpool microwave units. The bulb helps address dim or flickering lights inside microwaves and can replace several OEM numbers. When replacing, ensure the base size (E17) matches your current fixture and verify the model compatibility listed in product notes. A simple replacement may restore interior illumination quickly.
Key considerations: check base type (E17), confirm non-dimmable if your fixture expects a fixed brightness, and verify the model compatibility list. The bulb’s glass construction supports typical home-use environments, but handle carefully to avoid breakage. Installation requires no tools beyond unscrewing the old bulb and twisting in the new one.
BlueStars 8206232A KEI, 3-Pack

BlueStars offers a value bundle with multiple 40W, 125V E17 bulbs, intended as replacements for Whirlpool and other major brands. This package emphasizes straightforward installation and broad model coverage, including GMH and KMHS series microwaves. The listed replacement part numbers show compatibility with many OEM references, providing a single solution for households with multiple kitchen appliances. The dual benefit of a spare bulb reduces downtime when a light fails during cooking or maintenance.
Key considerations: ensure the model numbers you own are among those referenced in the listing, and note that this product includes more than one bulb for convenience. The bulbs are designed for quick screw-in installation, making them suitable for DIY replacements without professional help.
Snnalosses 40W Microwave Bulb, Pack of 8

The Snnalosses pack features eight 40W, 120V bulbs with a high-temperature tolerance suitable for microwave interiors. The bulbs have an E17 intermediate base and a clear glass design, with a 2.19 inch length by 0.98 inch diameter footprint. They are described as dimmable and rugged to withstand door-opening vibrations. The long-term durability is supported by shock and vibration-resistant construction, and the set provides a cost-effective way to replace multiple units or keep backups on hand for future maintenance.
Key considerations: confirm the dimmable feature if your microwave’s lighting circuitry supports dimming, and ensure the physical dimensions fit your fixture. The availability of several bulbs in one package reduces maintenance downtime, particularly for households with frequent bulb replacements or multiple appliances needing bulbs.
Maelsrlg LED Under Hood 40W Equivalent

The Maelsrlg LED bulb provides a 3W LED alternative to a 40W incandescent bulb, delivering about 380 lumens at 3000K (warm white). This LED option reduces energy consumption by up to 90% while offering a long lifespan—rated well beyond typical incandescent bulbs. Instant full brightness avoids warm-up delays, and the LED design produces no UV or IR radiation. It is suitable for under-hood lighting and other appliance illumination needs, offering better efficiency without sacrificing perceived brightness.
Key considerations: verify that your fixture accepts LED 3W replacements with an E17 base, and confirm that the color temperature (3000K) provides the warmth you prefer for kitchen environments. LED bulbs may have different dimming compatibility than incandescent bulbs, so check your microwave’s dimming behavior if applicable.
SerBion LED 3W Under Hood Bulb, 2-Pack

SerBion offers a 2-pack of 3W LED bulbs with a 125V rating and E17 base, designed as a 40W equivalent replacement for microwave lighting. Key features include high CRI (90+), ensuring color accuracy inside the appliance. The bulbs are dimmable and provide stable brightness via advanced dimming performance, allowing precise control to reduce glare. With a reported lifespan exceeding 6,000 hours, these LEDs emphasize long-term durability and energy efficiency while delivering a warm 2700K color rendition.
Key considerations: assess dimming compatibility with your specific microwave or range hood setup. A higher CRI can improve visibility of food and internal components, which may be beneficial for tasks requiring accurate color perception. Ensure the LED modules fit within the appliance’s lighting fixture and do not exceed its heat tolerance.
Buying Guide: Key Purchase Considerations
- Base compatibility: Most under-hood microwave lights use an E17 base. Confirm the base type before purchasing to avoid mismatches.
- Wattage vs. brightness: 40W incandescent equivalents are common; LEDs offer high efficiency with lower wattage but similar brightness. Check lumen output for a true brightness comparison.
- Dimming and control: Some bulbs are dimmable, others are not. If your fixture has a dimmer, choose a compatible dimmable bulb; otherwise, stick to non-dimmable options for simple replacement.
- Heat resistance and materials: Look for bulbs with heat-resistant glass and construction designed for appliance interiors, where temperature can rise during operation.
- Compatibility with brands and models: Listings often cite compatible microwave models. Cross-check against your model number (such as Whirlpool, GE, Maytag, Kenmore) to avoid mismatches.
- LED advantages: LED bulbs consume less energy and last longer, with options available in warm white (around 2700K-3000K) or brighter tones. Confirm dimming compatibility and heat tolerance for LED variants.
- Pack content and replacements: Some sets include multiple bulbs for convenience. Consider whether you want singles or multi-packs to cover multiple fixtures or future replacements.
- Warranty and returns: If you receive a damaged bulb or it fails early, check the seller’s return or refund policy to ensure a replacement is straightforward.
- Installation ease: Most bulbs screw in; avoid forcing connections. Ensure the power is off before replacing to prevent shock.
- Color temperature and perception: Warmer temps (around 2700K-3000K) create a cozy kitchen feel, while cooler temps offer better visibility for tasks. Choose based on preference and lighting needs inside the appliance.
