How to replace microwave monitor switch? If there isn’t voltage going to the transformer the problem is more than likely 2. The first thing you will have to do is Microwaves are the electro-magnetic radiations whose frequency ranges from 0.3 GHz to 300 GHz , These waves are mostly used for the non-broadcasting issues , Microwave motion detectors emit microwaves into the specific region and they detect any intrusion by analyzing the received microwaves frequency after the reflection from the intruder . However this is not a 100% accurate test. The switch is typically black and approximately an inch in length. In the normal operation of the circuit the closing of the oven door causes the closing of the power switch 26 and the opening of the monitor switch 40.
