Replace a Microwave Lightbulb
Most microwaves are equipped with an internal light that turns on when the door is opened or when the microwave is operational. This small halogen light is not necessary for the microwave to work, but does enhance its features and use. If the bulb in your microwave has burned out, here’s what to do.
Steps
- Unplug your microwave or shut off the power to the microwave at the breaker.
- Examine your microwave to find the vent. There will be a vent located either in the front, side or bottom of the machine, depending on make, model and mounting.
- Locate the screws holding the vent panel in place and remove them.
- Lift off the vent panel of the microwave and set it aside.
- Locate the box that the halogen light is kept in.
- Loosen and remove the screws that hold the cover of the box in place.
- Remove the cover to the light box.
- Unscrew the bulb from the microwave and remove it.
- Screw in a new bulb.
- Replace the cover to the light box and tighten down the screws.
- Replace the vent panel and tighten down the screws.
- Plug the microwave back in or reset the breaker.
- Open the microwave's door to test the new light bulb. If you’ve replaced the bulb correctly and the new bulb is working properly, then the light should go back on when you reopen the microwave’s door.
Tips
- Consult your owner's manual if possible to determine the exact size and type of light bulb needed. If your manual is not available, go through first 7 steps and take this bulb with you to the hardware store to purchase a new bulb. This will ensure you get the correct wattage for your particular unit.
- Some microwaves are not meant to have the bulb changed by the homeowner; in these cases, the bulb replacement may be covered under warranty. If you own the microwave, check the user manual and warranty information to see if a new light bulb and installation is covered under your microwave's warranty before attempting to change it yourself.
Warnings
- Never attempt to change the bulb in a microwave while the microwave is still plugged in or while power is being supplied.
- Do not attempt to change the light bulb from within the microwave's interior; always remove the vent panel and change the light bulb from within.
