The little bulb that lights the cooktop under an over-the-range microwave is one of the most replaced parts in the kitchen, and one of the most fiddly to shop for. It runs on an E17 intermediate base, smaller than a normal lamp, and it is usually rated 40 watts at 125 volts, but the part number on the box is what trips people up since several brands cross-reference the same fitting. The bulb also lives in a tough spot, right above a hot range and bolted to a vibrating appliance, so heat tolerance and a solid base matter. LED replacements run cooler and last far longer, which is appealing under a hood that bakes an incandescent, but you have to confirm the LED is rated for the enclosed, warm fixture or it can fail early. Dimmability is worth checking too if your microwave has a low night-light setting. We focused on fit and survival in the heat, since brightness is rarely the issue, longevity is.

Key buying factors

E17 base match

Microwave hood bulbs use the smaller E17 intermediate base, not a standard medium base. Confirm the fitting so the bulb actually threads into the socket.

Part number cross-reference

Brands list overlapping part numbers like 8206232A for the same fitting. Check that the listing covers your microwave's model before ordering.

Heat tolerance

The bulb sits above a hot cooktop in an enclosed hood. Choose one rated for that warmth, since heat shortens the life of an unsuitable LED.

LED versus incandescent

LEDs run cooler and last far longer but must be rated for enclosed use. Incandescent bulbs are a guaranteed fit but burn hotter and die sooner.

Dimmability

If your microwave offers a low night-light mode, confirm the LED is dimmable. A non-dimmable LED can flicker or buzz on the reduced setting.

Types explained

LED E17 replacement

A cool-running LED that drops into the E17 hood socket.

Best for: Anyone tired of replacing hot incandescent bulbs that burn out fast.
Incandescent E17 bulb

A traditional 40W filament bulb for a guaranteed fit.

Best for: A simple like-for-like swap with no compatibility worries.
Dimmable LED

An LED rated to dim for the microwave's night-light mode.

Best for: Units with a low cooktop light setting you actually use.
Multi-pack bulb

Several bulbs so you keep spares for the next burnout.

Best for: Households that replace this bulb often and want backups ready.

Care & usage tips

Let it cool first

The old bulb and the hood get hot during cooking. Wait for them to cool and unplug or kill the breaker before reaching up to swap the bulb.

Find the access cover

Most microwaves hide the bulb behind a small cover or grille under the unit. Check the manual so you remove the right panel instead of forcing anything.

Thread gently

The E17 socket is small and the bulb is glass. Turn it in by hand until snug without overtightening, which can crack the base or the socket.

Why this matters

An LED rated for enclosed fixtures is the real win here, because it sidesteps the constant burnout that plagues incandescent bulbs baking under a hot range hood.

Pro tip

If you switch to LED, make sure it is labeled for enclosed or appliance use, since an LED not rated for the trapped heat under the hood will fail nearly as fast as the incandescent it replaced.

Frequently asked questions

What base does a microwave hood bulb use?+

It uses the smaller E17 intermediate base, not a standard medium base. Confirm the E17 fitting and the 40W 125V rating so the bulb threads correctly into the socket.

Can I use an LED instead of incandescent?+

Yes, and it runs cooler and lasts longer, but it must be rated for enclosed or appliance use. An LED not built for the trapped heat under the hood can fail early.

Will it dim on the night-light setting?+

Only if the LED is dimmable. A non-dimmable LED may flicker or buzz on the microwave's low cooktop light. Incandescent bulbs dim without trouble.

How do I match the part number?+

Cross-reference codes like 8206232A against your microwave's model. Several brands sell the same fitting under overlapping numbers, so confirm yours is listed before buying.
