Maytag Oven Error Code 1d11

Error code 1d11 on a Maytag upper or single oven indicates the control board has detected a runaway temperature condition, meaning the oven temperature reached or exceeded 650°F while the door lock mechanism remained in an unlocked state. The primary suspect is the oven temperature sensor (RTD probe), and the diagnostic threshold is clear: a properly functioning sensor reads approximately 1080 ohms at 70°F, but the control board logged a resistance above 2237 ohms, which causes the board to receive a falsely elevated temperature signal and interpret it as a dangerous thermal event.

For homeowners, this means the oven's built-in safety system detected what it believed was an extreme overheating situation. The temperature sensor is a small probe mounted inside the oven cavity, typically at the upper rear wall. When its resistance drifts out of range, the control board can no longer accurately read the oven's actual temperature. Rather than risk a true runaway heating condition, the board shuts down operation and displays 1d11. The oven itself may not have actually reached 650°F. A failed sensor is often the culprit, not a genuine overheating event.

Until the fault is diagnosed and cleared, the oven will remain inoperable. Testing the sensor resistance with a multimeter is the correct first step before replacing any parts.
