How to replace a door interlock switch:
| || Replacing a door interlock switch |
NOTE: Before you begin any microwave repair, including this one, make absolute sure you unplug the microwave and discharge the capacitor first.
When you replace a door interlock switch, make sure the replacement switch is exactly 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 correct electrical specifications.
CAUTION: Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.
