This M/W is part of a wall oven setup. It won't heat. I replaced the mag tube, capacitor, diode, and control board. It doesn't sound like the high voltage side is kicking in. I thought that the relay on the board was bad and not putting power to the transformer. Nope. The problem with these units is that it has to be removed from the wall oven to check it out. I'm beginning to think that the transformer is bad even though it shows continuity. Does anyone have any experience with a bad transformer. I've never seen a bad transformer. I had one that was noisy but the unit still heated.
All help will be appreciated. Thanks
