| To check or replace the switch, you must open up the housing where it is. And yes, turn the power off first. First make sure none of the wires to it are shorted to each other. If it is a simple switch independent of the microwave, you should be able to pick up one from a hardware or Radio Shack. If it is integrated into the microwave controls, you will need to through the manufacturer. You may be able to pick one up from a local dealer or appliance repair service.
A number of years ago, I replaced a complicated, integrated switch for the blower and light on my range hood with a couple of switches from RS. |
