How to replace the cavity or interior light on an over the range microwave

Has the light bulb failed?

The cavity or interior light should come on when the door is opened or the microwave is operating.

If the display is on check or replace the light bulb.

The cavity light bulb is located behind the vent grille at the top front of the microwave oven, under the bulb cover, and is replaceable.

IMPORTANT: Use only an incandescent light bulb as a replacement.  Do not use an LED light bulb. 

Remove two screws on the top of the vent grille, tilt the grille forward, and lift it out.

Refer to the Use and Care Guide for vent grill removal instructions.  If you would like to download or view product literature for your appliance, please visit our Manuals and Literature page.

  • Open bulb cover and replace bulb.

  • Close bulb cover, replace vent grille, and secure with screws at the top of the vent grille.
