The oven control board sends voltages to the heating elements—bake and broil—depending on the user input and sensor settings. If one of the control board's relays ends up shorting, the board may send continuous voltage, which means the oven may continue to heat even after it is turned off at the controls. A defective control board must be replaced.
*GE Appliances technicians carry an extensive parts inventory on their service trucks. In the event a part is not available on the service truck, a follow-up service call may be required.
