Installing another breaker is not the way forward. Does the breaker screw to the busbars or does it just clip onto them.

How old is your panel is it the Stab-Lok style, can you show a pic.
clips on. Put the old one back on, still doesn’t work, put a new one in, works. But I’m not going to run the microwave yet.Installing another breaker is not the way forward. Does the breaker screw to the busbars or does it just clip onto them.
Can you tell me exactly the testing equipment I need and what I should test? Am I just testing the breaker? 2 breakers have stopped working. They don’t work when I put them back in. A 3rd new breaker works again but I don’t want to run the microwave until I can figure this out.You could lose a lot of time on trial-and-error swapping out of parts. It really does make sense to test, or get someone else to test, where the problem is. If for example it is the contact between the breaker and the panel busbar that is intermittent, swapping it will probably make it work again briefly, but so would putting the original one back. WIth proper test equipment it should be possible to nail this in a few minutes.
Great idea. I switched both the breakers and the wires. The breaker I thought was broken does work with another wire both in the same place and different place. The microwave wire isn’t working in any breaker at any place. So it’s not the breaker I’m concluding. Even though the outlet doesn’t work I’m still getting a a strong electrical reading from the outlet. I removed the outlet and tried swapped it in a different place and it works. So it’s not the outlet. Am I right to conclude this is a wire problem? I’ve got to crawl into the attic and take a look to make sure it’ looks goodThat is Square D QO. Have you tried the breaker in a different position or temporarily connect to another 20A breaker, don't move it just connect your wire to another breaker.
Just got out of the attic. Found the 12 gauge from the box was wired to a14 gauge extension wire up there. The wire nut on the white wire was melted. My idea is to continue a12 gauge extension all the way to the outlet (5 feet). Otherwise, does this wiring look good? I’m running another receptacle off of the dedicated microwave box below it to plug in the gas oven which draws a trickle for sparks, light and timer.Is the microwave outlet the only accessory on this circuit.
