The controls work, but the light can't be seen. Is there a way to replace the light without going to a repair store?

If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.

If not, chances are you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

If you don't have your instructions, please reply back with your brand and model number.

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.

On a counter top model, be sure it's unplugged, but otherwise ignore the instructions above this paragraph.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H Torx 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.

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

Counter top lights not working. new bulbs replaced. still not working.


We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

My over the range microwave oven light(underneath) does not work. The bulbs were tested, they are OK. Is there a fuse to replace?


Maybe. In some Whirlpool models there are several fuses.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

We had a lightning strike near our home and our Ewave OTR microwave quit, nothing works but the light inside and the vent fan comes on automatically. We've been told that there is a fuse that can be...


If the light and fan work then it cannot be the fuse. When the fuse "blows", it stops the electricity totally from flowing into the microwave and nothing will work or respond. The fuse is behind the control panel and this requires several hidden screws to be removed. Also, you must be very careful of the 2000 volt charge that is stored in the wiring further into the compartment behind the control panel. Therefore, do not attempt to open the micro control panel without proper service knowledge.
Because you say the light and fan operate, the fuse (as I stated ) is not your answer; most likely the problem is in the control panel circuit board. The circuit board is like any sensitive electronic component that goes crazy when there is a voltage surge that strikes it such as lighting throughout the house wiring. The board needs to be replaced unless you can have an electronic wizz-kid test is out and repair it , or just by a new board. By the way, the board is not cheap and may be difficult to locate since I understand the the manufacture stopped producing it.
