What 1d22 means on a Maytag range

Error code 1d22 on a Maytag range indicates the control board detected a runaway temperature condition in the lower oven cavity, with the door locked, where the measured temperature reached or exceeded 950°F. This threshold is well beyond any normal bake or broil cycle and signals that the oven is no longer regulating heat correctly. The two primary suspects are the lower oven temperature sensor, which feeds temperature data to the control board, and the relay contacts on the control board or relay board, which control power to the bake and broil elements. A stuck relay can allow continuous power to an element even when the control board commands it to stop.

For homeowners, this means your lower oven lost the ability to regulate its own temperature and overheated significantly during a self-clean cycle or a cooking cycle with the door locked. The oven detected this dangerous condition and shut down to protect itself and your home. This is not a code to ignore or bypass.

The door-locked condition referenced in the code typically occurs during a self-clean cycle, making that the most common scenario where 1d22 appears. Clearing power resets the lockout, but the underlying cause must be diagnosed before running the oven again.

Common causes of 1d22

  1. 01

    Stuck or shorted relay contact on control or relay board

    Part replacement

    A relay contact that welds closed keeps continuous voltage on the bake or broil element regardless of control commands, causing unchecked temperature rise. This is a primary suspect when runaway heat is confirmed and the sensor reads accurately.

  2. 02

    Failed lower oven temperature sensor

    Part replacement

    A shorted oven temperature sensor sends an artificially low resistance reading to the control board, making the board believe the oven is cooler than it actually is and prompting it to keep the element energized. The oven overheats while the board sees no reason to shut off.

  3. 03

    Damaged or shorted sensor wiring harness

    Part replacement

    Wiring in the lower oven cavity can degrade from repeated heat exposure. A short in the sensor harness produces the same false-low resistance signal as a failed sensor, causing the control board to over-fire the element.

  4. 04

    Control board software fault or failed thermistor input circuit

    Part replacement

    In less common cases, the control board's input circuit for the lower oven sensor fails internally, losing the ability to read temperature accurately and allowing elements to run unchecked. If the sensor and wiring check out within spec, the control board itself is the remaining suspect.

Frequently asked questions about 1d22

What does error code 1d22 mean on a Maytag range?
Code 1d22 means the control board detected a runaway temperature condition in the lower oven cavity, reaching 950°F or higher, while the oven door was locked. The oven shut down as a safety response. This most commonly occurs during or after a self-clean cycle. The two systems to inspect are the lower oven temperature sensor and the relay contacts that control power to the heating elements.
Is it safe to use my Maytag range while error code 1d22 is active?
No. Code 1d22 indicates a confirmed temperature runaway condition, meaning the oven could not regulate heat and exceeded 950°F. Running the oven again before identifying the cause risks another uncontrolled overheating event. Disconnect power, allow the oven to cool completely, then diagnose the sensor and relay contacts before attempting any further use.
How do I fix error code 1d22 on a Maytag range?
Start by disconnecting power to the range for at least five minutes to reset the control board and release the door lock. Once power is restored, check the lower oven temperature sensor resistance at room temperature, which should typically read around 1080-1100 ohms on most Maytag sensors. If the sensor reads shorted or out of spec, replace it. If the sensor checks out, inspect the relay contacts on the control or relay board for signs of welding or pitting and replace the affected board. A repair technician should handle relay board replacement if you are not comfortable working with the internal electronics.
How much does it cost to repair error code 1d22 on a Maytag range?
A replacement lower oven temperature sensor typically costs $20 to $50 in parts and is a manageable DIY repair for most homeowners. Replacing a relay board or main control board runs $100 to $300 or more depending on the model, plus labor if professionally serviced. Labor for a range control board replacement from an appliance technician commonly adds $100 to $200. Diagnosing the sensor first is the most cost-effective path since it is both the most likely cause and the least expensive fix.
Can disconnecting power clear code 1d22 on a Maytag range permanently?
Disconnecting power clears the stored code and resets the control board, but it does not fix the underlying cause. If the temperature sensor is shorted or a relay contact is stuck, the runaway condition will repeat the next time the oven reaches high temperatures. The code will return, typically during the next self-clean cycle or high-temperature cooking cycle. Always diagnose and repair the root cause before returning the oven to service.
