Key Steps for Replacing a Door Interlock Switch in a Microwave
When you replace a door interlock switch, make sure the replacement switch is the same size. It should have the same or better electrical specifications: terminal configuration and current rating. As you remove the faulty switch, take note of which wire goes where.
Rely on the markings on your old switch to ensure the correct alignment for the switch. You cannot depend on location alone because your new switch may have a different arrangement. Be sure the new switch lines up properly with the actuating mechanism. Finally, use your ohmmeter to check and make sure the new switch is performing under the correct electrical specifications.
If your microwave does indeed have a reset button, it might save you from unnecessary work. For more detailed guidance, you can check out this Does Microwave have a reset Button? resource.
