GE combination wall oven and microwave error codes

If the oven actually overheated, the electronic oven control board likely has a stuck relay. Replace the electronic oven control board. If the oven is at room temperature, the oven temperature sensor could be defective. Disconnect electrical power to the oven and measure the oven temperature sensor resistance using a multimeter. You should measure about 1,100 ohms of resistance at room temperature. If the resistance is off by more than 100 ohms, replace the oven temperature sensor. If the resistance is correct, replace the electronic oven control board.

The electronic oven control board can't regulate oven temperature. Disconnect electrical power and replace the electronic oven control board.

Disconnect electrical power to the oven and check the wire harness connections between the oven temperature sensor and the electronic oven control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, measure the oven temperature sensor resistance using a multimeter. You should measure about 1,100 ohms of resistance at room temperature. If the resistance is off by more than 100 ohms, replace the oven temperature sensor.

The electronic oven control board can't calibrate the oven temperature. Disconnect electrical power to the oven and replace the electronic oven control board.

Disconnect electrical power to the oven and check the wire harness between the meat probe receptacle and the electronic oven control board. Reconnect any loose wires or replace the wire harness if damaged. Replace the meat probe receptacle if damaged. If the wire connections and meat probe receptacle are okay, replace the meat probe.

Disconnect electrical power to the oven and check the wire harness connections between the electronic oven control board and the bridge control board. Check the wire harness connections between the electronic oven control board and the FAD (Fan Apparency Device) control board. Reconnect any loose wires or replace any wire harness if damaged. If the wire harness connections are okay, replace the electronic oven control board.

Disconnect electrical power to the oven and check the wire harness connections between the electronic oven control board and the bridge control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire harness connections are okay, replace the electronic oven control board. If the problem continues, replace the bridge control board.

Disconnect electrical power, wait 30 seconds and restore power. If the code returns, replace the electronic oven control board.

Disconnect electrical power and check the wire harness between the door lock and the electronic oven control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire harness is okay, replace the door lock. If the problem continues, replace the electronic oven control board.

Don't attempt to open the oven door when the oven is still hot during a cleaning cycle. Once the oven cools, disconnect electrical power and check the wire harness between the door lock and the electronic oven control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, replace the door lock. If the problem continues, replace the electronic oven control board.

Disconnect electrical power and check the wire harness between the door lock and the electronic oven control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, replace the door lock. If the problem continues, replace the electronic oven control board.

Disconnect electrical power and check for obstructions blocking the cooling fan blade. If you find no obstructions, replace the cooling fan. If the problem continues, replace the FAD control board.

Disconnect electrical power and check for obstructions blocking the cooling fan blade. If you find no obstructions, replace the cooling fan. If the problem continues, replace the FAD control board.
