Kyle lives in the Deer Valley area of Phoenix and had a GE Oven and microwave combination unit that would not heat. We found that the main oven control board had shorted out and after repairing the oven control board the unit was back to normal operation. The model number for this unit was JT965BF1BB. Other units that may also have this problem are JT965BF2BB JT965BF3BB JT965BF4BB JT965BF5BB JT965BF6BB
