Maytag Dryer Error Code F-22

F-22 indicates that the exhaust thermistor has gone open circuit, meaning its resistance exceeded 50 kΩ, which the control board reads as a temperature below 18°F. This condition must persist for one minute during normal operation to trigger the code, but it appears immediately in Factory Diagnostic Mode. The most common causes are a failed thermistor, a loose connector, or a broken wire in the sensor circuit.

You should not continue running the dryer while this code is active. The exhaust thermistor is part of the thermal monitoring system, and operating without a valid temperature reading means the control board cannot properly regulate drying cycles or respond to overheating conditions. Continued use could pose a fire risk or cause damage to other components.

Unplugging the dryer or cycling power may temporarily clear the code, but it will return as soon as the dryer runs and the control board detects the open thermistor circuit again. A reset does not address the underlying hardware problem. The fault needs to be physically diagnosed and repaired before the code will stay cleared permanently.

A knowledgeable DIYer can diagnose this code with a multimeter by checking the thermistor resistance and testing continuity along the wiring harness. If the thermistor is the culprit, replacing it is a straightforward repair on most Maytag dryer models. However, if the wiring or control board is involved, professional diagnosis is recommended to avoid misdiagnosing an expensive component.

If only the thermistor needs replacement, parts typically range from $10 to $40 depending on the model, making it one of the less expensive dryer repairs. Adding professional labor usually brings the total to somewhere between $80 and $200. If the control board is the root cause, parts alone can range from $100 to $300 or more, with labor on top of that.
