Use your screwdriver to remove the two screws holding the door switch in place. Carefully lift the old switch out of the microwave.
Step 5: Install the New Switch
Align the new door switch with the mounting holes and insert the screws. Tighten the screws securely but do not overtighten.

Place the front panel back onto the microwave body and align it with the mounting holes. Insert the two screws at the bottom of the panel and tighten them.
Step 8: Test the Switch
Plug the microwave back in and turn it on. Open and close the door to ensure the door switch is functioning properly. The microwave should only operate when the door is closed.
