Question about Whirlpool MH6130XEB/Q Microwave Oven
2 problems- When starting it goes on then off with a strange sound in the control area then comes on & completes the time until today it comes on then goes off & doesn't come on but sounds like the switch continues to cycle trying to come on;timer continues to run.
Another problem- when operating there is a vibration that is louder that normal. It sounds like it is coming from the upper part of the microwave. occasionally it stops but not for very long.
Sounds like you just fried your magnetron. Normally when they go bad, they make a very loud noise like what you described. The smell concerns me because you may have ruined the waveguide as well. If the magnetron burns through the protective painted surface of the waveguide, the waveguide is ruined. In most microwave ovens this means replacing the entire unit because the waveguide is not replaceable. Putting a new magnetron in a damaged waveguide will result in the same arcing and eventual failure. In addition to the magnetron, the following components are part of the same high voltage network: HV Transformer HV Diode HV Capacitor Magnetron Thermal Cut-Out Any one of these components could have also been damaged. I DO NOT recommend taking any voltage measurements inside the HV network. Potentials of over 4000 volts can be reached and make it very dangerous for the do-it-yourselfer. Taking resistance readings with the unit unplugged is strongly encouraged. If you decide to pursue a repair, inspect the magnetron tip and inside of the waveguide first. If the magnetron is melted and/or there are burn marks inside the waveguide, a new microwave may be a in order. This actually may be a better option than an expensive repair. I hope you find this advice helpful.

SOURCE: No power from Whirlpool.
The problem was a defective switch. There are 3 switches on mine. 1 on the top door latch, and 2 on the bottom. one of the switches on the bottom connected the power and neutral together, unless it was activated at the same time as the other 2, causing the breaker to trip or the internal fuse to blow. When unhooking the wire going from this switch to the other switch, everything works great now. Though I still need to replace the switch.
And for Basic 1. Yes my microwave did have a fuse in it it's ceramic, I got a pack of them at Radio Shack 4 for 3$ 250V 20 Amp. There should be a wiring diagram inside the microwave, mine was inside a black bag, so it may be hard to see.
Mine was up top next to the fuse behind the Plastic Grill and then a small metal grill. Some are behind the control panel, to fix this remove the screw at the top and then slide the control panel up and it should unhinge.

The magnetron has failed and has damaged the waveguide. This type of failure is generally unrepairable. First look in your owners manual for specific warranties, then contact Whirlpool and explain to them what has happened.

That's how it would sound if you were cooking on a power level less than full power.
If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.
If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.
The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.
Let us know if the hard reset doesn't fix it.

Tips for a great answer:
I appreciate your inquiry, David!
From the information you have provided your Frigidaire microwave shuts off and then will factory restart. It sounds like a possible problem with your control panel or a faulty wiring harness. I would recommend seeking assistance from a professional. They would need to properly disassemble your microwave and test each electrical component to pinpoint the problem within it. The technician has the appropriate tools needed to complete the repair without causing personal injury or any future issues with the microwave. Best of luck! -Matt
