William W Rockville , MD March 08, 2016 Appliance: Model GE JTP95BA1BB Bad magnetron Not to difficult to fix. It was a Microwave/Wall-oven Combo. Hardest part was unscrewing removing all of the covers. Once removed it was easy to get at the magnetron. Be sure capacitor is discharged it has very high voltage.
