Jenn-Air Oven Error Code 1d22

Error code 1d22 on a Jenn-Air oven indicates a runaway temperature condition in the lower oven while the door is in the locked position. Specifically, the oven has detected or projected a temperature exceeding 950°F, which surpasses the safe operating threshold for normal baking and broiling cycles. When this fault occurs, the control board disables the affected lower oven functions to prevent potential damage to the cavity, door gasket, internal wiring, or surrounding cabinetry. This condition is most commonly associated with a self-clean cycle, during which the door locks automatically and temperatures rise significantly above normal cooking ranges.

The primary diagnostic focus is the lower oven temperature sensor, also called the RTD (resistance temperature detector) probe. At the point of fault, the sensor resistance should read greater than 2787 ohms. A reading at or above this value suggests the oven temperature genuinely approached the runaway threshold, pointing to a control board or relay issue that allowed excessive heat. A reading significantly below this value indicates a shorted or degraded sensor that reported a false high temperature to the control board, triggering the fault incorrectly.

Two separate failure paths can produce this code: a faulty temperature sensor sending inaccurate high readings, or a control board with a stuck relay that continues supplying power to the bake or broil element beyond the setpoint. Identifying which path applies requires measuring sensor resistance and inspecting element cycling behavior. Because the door is locked during this fault, the control's safety logic prevents the door from releasing until temperatures fall to a safe level, which can complicate immediate diagnosis.
