What 1d22 means on a Maytag oven

Error code 1d22 on a Maytag oven indicates the control board has detected a runaway temperature condition in the lower oven, with the oven door locked and an internal temperature reading at or exceeding 950°F. The trigger is a temperature sensor (oven sensor/RTD probe) reporting resistance above 2787 ohms, which corresponds to an abnormally high temperature signal. The control board interprets this as an uncontrolled temperature spike and locks the door as a safety measure. This code is specific to the lower oven cavity in dual-oven configurations.

For homeowners, this means your oven's built-in safety system detected what it believes is a dangerously high temperature in the lower oven. The door locks automatically to prevent you from opening it during this condition. The most likely cause is a faulty oven temperature sensor sending incorrect resistance readings to the control board, rather than the oven actually reaching 950°F. However, a runaway bake or broil element is also possible.

Do not attempt to force the door open while the code is active. Power cycling the oven may reset the door lock temporarily, but the underlying cause must be diagnosed before resuming normal use. Testing the oven sensor resistance is the correct first step.

Common causes of 1d22

  1. 01

    Failed oven temperature sensor (RTD probe) with high resistance drift

    Part replacement

    The lower oven temperature sensor has drifted out of spec and is reading above 2787 ohms, causing the control board to calculate an internal temperature at or above 950°F. A sensor reading this high resistance value is defective and will need replacement.

  2. 02

    Damaged or shorted oven sensor wiring harness

    Part replacement

    Wiring between the lower oven temperature sensor and the control board can become pinched, burned, or corroded, causing resistance readings to spike beyond the 2787-ohm threshold. Inspecting and replacing the harness segment will correct the false high-resistance signal.

  3. 03

    Runaway bake or broil element in lower oven

    Part replacement

    If the bake or broil element is stuck energized due to a failed relay on the control board, the lower oven can genuinely overheat and reach dangerous temperatures, triggering the 950°F threshold legitimately rather than as a sensor error.

  4. 04

    Faulty oven control board

    Part replacement

    If the sensor and wiring both test within spec, the control board itself may be misreading the sensor signal or failing to regulate element output, producing a false or real runaway condition. Control board replacement is typically a last-resort diagnosis after sensor and wiring are confirmed good.

Frequently asked questions about 1d22

What does error code 1d22 mean on a Maytag oven?
Error code 1d22 means the control board detected a runaway temperature condition in the lower oven, with the temperature reading at or above 950°F and the door locked. The code is triggered when the lower oven temperature sensor reports resistance greater than 2787 ohms. This is most commonly caused by a defective oven temperature sensor rather than the oven actually reaching that extreme temperature.
Is it safe to use my Maytag oven with error code 1d22 active?
No, you should not use the oven while 1d22 is active. The code indicates either a genuine overheat condition or a sensor failure that is causing the control board to misread oven temperature. In either case, operating the oven without resolving the root cause risks an actual overheat event or continued component damage. Keep the oven off and unplugged until the sensor and wiring are tested and confirmed or replaced.
How do I fix error code 1d22 on a Maytag oven?
Start by testing the resistance of the lower oven temperature sensor using a multimeter. Disconnect the sensor and measure its resistance at room temperature; it should read approximately 1080 to 1100 ohms at 70°F on a standard RTD probe. If the reading is above 2787 ohms or open, the sensor is faulty and needs replacement. If the sensor reads correctly, inspect the wiring harness for burns, corrosion, or pinched wires between the sensor and the control board.
How much does it cost to fix the 1d22 error code on a Maytag oven?
A replacement lower oven temperature sensor typically costs between $20 and $60 for the part, and replacing it is a moderately easy DIY repair requiring only a screwdriver. If the wiring harness is damaged, parts and labor from a technician can range from $100 to $200. A control board replacement, if needed, can cost $150 to $350 or more for the part alone, making professional diagnosis worthwhile before purchasing one.
Why is the door locked on my Maytag oven and showing code 1d22?
The door locks automatically when 1d22 is triggered because the control board has detected a temperature at or above 950°F in the lower oven. This is a built-in safety response to prevent the door from being opened during a potential overheat condition. After cutting power to the oven for several minutes and restoring it, the door lock may release. However, the code will likely return if the faulty sensor or wiring is not addressed first.
