How to Change the Light Inside the Microwave Oven

Some microwave ovens are built with a removable glass or plastic lens covering the inside light bulb. If your microwave has this feature, you can replace the interior light yourself when it eventually burns out. Microwaves with a sealed light fixture can only be repaired by a trained technician, as replacing the bulb involves opening the cabinet and coming into contact with parts that carry high voltage. Look inside your appliance to locate the cover plate, which is held in place by a tab or screw. If you have either type of fastener, you can change the bulb.

The bulb is inside the microwave under a cover panel.

Step 1

Unplug the microwave power cord from the electrical outlet.

Step 2

Open the appliance door to locate the light bulb cover panel.

Step 3

Extract the small screw holding the panel inside the appliance, typically on one of the side walls, or insert a flat-blade screwdriver into the tab to pry open the panel.

Step 4

Unscrew and remove the old bulb.

Step 5

Insert the new bulb in the socket and twist clockwise by hand.

Step 6

Replace the cover plate and secure with the screw or press the plate to snap the tab into the locked position.

Step 7

Close the microwave door and plug in the power cord.
