GE Microwave JVM3160RF5SS monitor switch wires shorted

This microwave had a blown fuse when I got it.

I tested all the switches with wires disconnected and they all work properly opening and closing the door. Replaced fuse and turned it on. Put a cup of water in and tried to start and got a message to insert food. As if it didn’t recognize the door opening and slowing.

I double check switches and the monitor switch wires are shorted together. The switch works fine if I disconnect the wires. The wires (2 white) lead back to the transformer. If I unplug transformer wires the switch works like it should. The transformer tested good with 2-3 ohms and no short to ground.

Is the transformer bad??

Appreciate any help on this.

This might help. I believe it still to be a switch issue. 2 switches are normally closed and one is normally open when the door is open. Could also be misalignment. Did you take pictures of the wires when you disconnected them? GE will require you to open the door when you plug it back in before you cook.

Thank you, I replaced the switches with other ones I had on hand and it’s working like new again.
