Hello & Welcome to FixYa

To replace the light bulb first remove the screws located on the vent grill at the top of the microwave, tilt the grill back and then pull away to remove. After this open the light cover , you have to remove the screws so that you can discard the old light bulb and then replace it with a new one. Please get back to me if you have any other questions.

Most lights in Microwaves are accessed by removing the case cover.

Sometimes the cover screws at the front near the door are kind of hidden, while the ones at the back are readily removed.

DO unplug the unit when working on it and avoid touching any wiring within the unit while working on it.

Remove the lamp and take it as a sample to get an EXACT replacement.

Check the owner's manual to see if yours is a model which allows access to the lights without pulling it down from the wall.

Accessing the lights on some models will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download owner's manuals and installation instructions for several brands (including Amana, Frigidaire, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

Most bulbs can be matched up at hardware stores, home improvement centers, and places like Wal-Mart or even large grocery stores.

Many use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

You will need these instructions, because to replace the bulb, you will need to pull the microwave down from the wall mount and remove its cover.

Always unplug a microwave before removing or installing any bulbs.

And it's best to have two people since the microwave can be heavy and awkward.

Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

In some over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this.
