Maytag Oven Error Code 1d22

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.

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.

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.

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.

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.
