I will be happy to help you out. Can I get the model number to the microwave?
You more than likely have a defective magnetron. Ge has a five year warranty on this. If your microwave is less than five years old you can call them and they will fix it for free. If the microwave is more than five years old I would suggest buying a new one.
The magnetrons for some microwave are close to 180 dollars.
Let me know if this has been helpful to you. Thanks for using JustAnswer.com
I tell customers all the time. "I'm glad I didn't make the machine, I'm only here to fix it"
I apologize for the bad news. I hope I was able to help you out a little bit though.
