The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

Not clear what to explain but would look at the front control switches, commond problem, to see just play with the door open and closing to see what happen's with the fan, it's probroly not making proper contact, the other problem I can thing of is bad thermal heat sensor, there should be two or three of them, you need to know the basic what they do to test them just jump them, and try the unit and see if the problem stop to see witch termal is deffective.
Hope this help

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.
The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.
See the attached sample photo.

SOURCE: microwave won't heat
Sorry my Clarification Request came out as a single blob of a paragraph.
That's not how I typed it. I never write that way!
So I've pasted it here, but as a solution.
Magnetrons generally should last about 2000 hours, but several factors can shorten that.
If it's not OVER ten years old (from the purchase date or the date on the tag inside the unit) then the magnetron is still under warranty.
From the owner's manual:
"For the second through the tenth year from the date of original purchase
"The magnetron tube, if the magnetron tube fails due to a defect in materials or workmanship. During this nine-year limited warranty, you will be responsible for any labor or in-home service costs.
"For the above limited warranty: To avoid any trip charges, you must take the microwave oven to a
General Electric Customer Care® servicer and pick it up following service. In-home service is also
available, but you must pay for the service technician’s travel costs to your home."
GE Customer Service is here, and you can verify the warranty status and find your nearest authorized servicer.
If you're sure the magnetron's bad, it's still under warranty, and you or a friend are handy, they will send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.
It does sound like the magnetron overheated and the magnetron's thermostat opened until it cooled down.
An overheating magnetron can be due to:
When you hit Start to microwave, do the inside light, cooling fan, and turntable all come on?
Any unusual noises? Is it louder or quieter than usual?
We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.
You can find helpful exploded view diagrams and order parts if needed by entering your full model number from the tag on the oven here.
Let us know what you find out or decide.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I would suggest that the overheat stat on the magnetron has blown. If you are happy it's a simple thing to do but just make sure you disconnect from the mains before removing the cover and make sure that the High voltage capacitor is discharged. If you are not sure a qualified service tech will be able to fix this for you at little cost.
Hope this helps
