Jenn-Air Oven Error Code 1d11

Error code 1d11 on a Jenn-Air oven indicates a runaway temperature condition with the oven door in the unlocked position. This means the control board has detected that the oven cavity temperature is climbing beyond expected parameters and, critically, the temperature sensor is reading a resistance value greater than 2293 ohms. In a properly functioning oven, the temperature sensor (also called an RTD probe or oven temperature sensor) produces a predictable resistance curve: resistance increases as temperature rises. A reading above 2293 ohms signals to the control that the oven is operating at an abnormally high temperature, triggering the runaway condition.

When 1d11 is triggered, the control board responds by disabling all outputs. This is a protective measure designed to prevent overheating that could damage the oven cavity, surrounding cabinetry, or pose a fire hazard. The door being unlocked is a relevant qualifier because the control logic distinguishes runaway conditions during normal operation from those occurring during a self-clean cycle, where the door lock engages. This code specifically flags runaway during standard use with the door unlocked.

The most important first diagnostic step is to measure the actual resistance of the temperature sensor using a multimeter. A reading above 2293 ohms when the oven is at or near room temperature points strongly to a failed or degraded sensor. However, wiring faults between the sensor and the control board, or a failing control board itself, can also produce erroneous resistance readings that trigger this code. A thorough diagnostic should evaluate the sensor, its wiring harness connections, and the control board before replacing any component.
