Oven overheats, burning food even at normal settings, no error code

Safety first: If the oven is overheating uncontrollably, shut off power at the breaker immediately.

• Check sensor: Test the oven temperature sensor resistance at room temperature and at a known elevated temperature if possible. Replace if readings are incorrect or unstable.
• Inspect control board: Look for a relay welded closed (burnt contacts) on the EOC. If an element stays on constantly, replace the EOC.
• Verify wiring: Ensure the power cord is wired correctly to the terminal block according to the installation manual.
• Door seal: Replace a damaged door gasket that may cause hot air to escape and affect sensor readings.
• Re-test with thermometer: After repairs, verify temperature accuracy with an oven thermometer and adjust calibration if needed.
