Jenn-Air Oven Error Code 1d22

Error code 1d22 indicates a runaway temperature condition in the lower oven, where the temperature reached or was projected to exceed 950°F while the door was locked. The control board disables lower oven functions automatically as a safety measure. This code most commonly appears during or after a self-clean cycle. Diagnosis starts with checking the lower oven temperature sensor resistance, which should read above 2787 ohms at the point of fault.

No, you should not attempt to use the lower oven while this code is active. The control board has disabled lower oven functions specifically because a dangerous temperature condition was detected. Using the oven before diagnosing and correcting the underlying cause risks fire, damage to the appliance, or injury. The upper oven, if present and unaffected, may still be operable, but confirm this carefully before use.

Repair costs depend on the root cause. A lower oven temperature sensor typically costs between $20 and $60 for the part, plus labor if a technician is doing the work. A control board replacement is more expensive, generally ranging from $150 to $400 or more for the part alone depending on the model. Total repair costs including labor commonly fall between $100 and $600, with control board replacements at the higher end of that range.

A knowledgeable DIYer can start by measuring the resistance of the lower oven temperature sensor at the sensor connector and inspecting the wiring harness for damage. If the sensor is out of spec, replacing it is a straightforward repair. However, if the control board relay is stuck or the board itself has failed, replacement of the control board is more involved and may be better suited for a qualified technician.

Disconnecting power to the oven for several minutes may temporarily clear the code and allow the door to unlock once the cavity cools to a safe temperature. However, if the underlying fault, such as a bad sensor or stuck relay, is not corrected, the code will return during the next high-heat cycle. A reset is useful for initial diagnosis but is not a repair.
