Oven displays E2 and may overheat or shut down quickly
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker and allow the oven to cool completely.
Inspect and test the sensor:
- Access the oven temperature sensor from inside the cavity (rear wall).
- Remove the screws and pull the sensor forward to access the connector.
- Disconnect and measure resistance at room temperature. A very low resistance (near 0 Ω) indicates a shorted sensor.
- Inspect the sensor wiring for melted insulation or contact with metal surfaces.
- Replace the oven temperature sensor if shorted or damaged.
Check for wiring shorts:
- Remove the rear panel and trace the sensor harness to the main control board.
- Look for pinched or burnt wires, especially near the oven cavity and high-heat areas.
- Repair or replace any damaged harness sections.
- Reseat the connector on the main control board.
If the sensor and wiring are good but E2 remains, the main control board may be misreading the sensor and should be replaced by a technician.
