Board Latch WB02X21662

Unplugged microwave from wall outlet removed the cover with standard phillips #2 screwdriver and tamper proof screw bit driver. For safety shorted across capacitor with insulated needle nose pliers to discharge.
With P2 screwdriver removed 2 latch board screws and rotated latch board to access switches. Even though only the bottom pr ... Read more imary interlock switch was mechanically broken, I replaced the upper primary interlock switch also. With a DVM I checked the middle switch which tested good. The old switches can be carefully removed from the latch board by slightly bending the lock tabs and unplugging them, installation is the reverse of removal. I tested the release button and latch mechanism before replacing the cover. I tested the microwave only with the cover on for safety. Parts arrived quickly and easy repair on an 18 year old reliable microwave. A year ago, I replaced the magnetron, capacitor and diode on the same unit which did not heat.
