Oven overheats and burns food even at low temperature settings, no error code

Safety: Disconnect power immediately; overheating can be a fire risk.

• Do not use the oven: Until the cause is identified and repaired, avoid operating the oven.
• Test sensor: Remove and measure the NTC sensor resistance. A very low resistance at room temperature indicates a shorted sensor.
• Inspect wiring: Ensure the sensor is connected to the correct terminals on the control board and that no wires are shorted.
• Check control board: If the sensor is correct, inspect the board for a stuck relay (contacts welded closed). Replace the board if necessary.
