Possible Causes
Shorted oven temperature sensor (RTD), Shorted sensor harness to chassis, Failed EOC sensor input circuit
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before working on the oven.
- Test sensor:
- Access the oven temperature sensor connector (from inside cavity or rear panel).
- Disconnect the sensor and measure resistance at room temperature. It should be about 1050–1100 Ω.
- A very low resistance reading (near 0 Ω) indicates a shorted sensor; replace it.
- Inspect harness: With the sensor disconnected, check the harness from the sensor to the EOC for pinched or melted insulation touching metal. Repair or replace any damaged wiring.
- Check control board: If sensor and harness are good, the EOC may be falsely reading a short. Replace the electronic oven control (EOC) if the error persists.
