It will vary from unit to unit what type of lamp or bulb is used, You might do one of several things--read the owner manual as instructions are often there, if a major brand call customer service with the model number.

Search With Google for the manual with the model number and look on You Tube who often has video instructions based and model, brand or general description of what you want to do: :"how to replace the bulb in my microwave" etc.

Yes, take the rack out and recycle it. I do not know why these micro-wave company put racks in the micro wave ovens. You get some insulation on the inside the micro flaking off next the rack.


The mega-tron tube is a very high energy transmitter. The energy will come out of the top inside the micro wave oven in a wave guide. Micro wave energy that generation by the tube is high frequency into Gega Hertz. You have a metal tray in side the micro wave acts like a big capacitor it stores energy in form of heat the next you know it look like Marconi is putting on a lighting display.



Leave the wire tie on a loft of bread and put in you micro wave oven to defrost. The next thing you might see is a load bread burning, instant toast. ----The use of micro wave were invented by the British before WWII.

just disconnect from the power and take out the screws from the cover around and you will see a plastic color white then remove a screw from them and you find the bulb replace and return all parts back

Ccess to the bulb is under the outer cover of the micro wave. Unplug the unit for a few hours before removing the covers. Once the cover is off you will see where the bulb is and you can replace it. Replace and secure all the covers before plugging the device in again.

micro waves use a tube inside that generates micro waves and like a light bulb they eventually blow out. the tube is not considered replaceable and cheaper to just get new unit.

If there's no obvious removable cover over the bulb (most often on the rear or side) and the owner's manual doesn't address it, then disassembly will be required.

You'll need to remove the outer cover (wrapper) to get to the bulb.

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 (and 20A ceramic fuses) can be had locally in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

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