SOURCE: Light bulb replacement in a Tappan Microwave

Hi Mike.

Difficult to say on yours. You may try the following. On the back or side, if there is a little cover that's screwed into the panel. Otherwise browse around on the inside. Be sure to unplug the micro before checking. Once found be sure to replace with a microwave lamp and not a fridge lamp. There is a difference. Good Luck,JUS004

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.

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 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.

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

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 no bright, too. Sometimes this will similarly affect the exhaust fan operation or inside light, too.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

If you see no removable panel inside the cavity, it will be necessary to remove the housing to replace the bulb. Because of the nature of microwave energy, the fewer sharp edges and other irregularities in the cavity, the happier the magnetron is since all those have some effect on the distribution of the energy and efficiency of the unit. That's why one should avoid having any larger metallic container in a microwave. Using aluminum foil to prevent the drying out of certain types of foods is permissible because the ratio between moisture content of the food and the reflection of energy caused by the foil is not significant and the energy is mostly absorbed instead of reflected.
