Maytag Washer Error Code d2/F22

The d2/F22 code indicates a dryer exhaust thermistor open error. It means the exhaust thermistor is reading a resistance greater than 50 kΩ, which corresponds to a temperature below 18°F, for at least one minute during normal operation. This signals to the control board that the thermistor circuit has lost continuity, pointing to a failed sensor, broken wire, or disconnected connector.

It is not recommended to continue running the unit with this error active. Without a functioning exhaust thermistor, the control board cannot properly monitor drying temperatures, which could lead to overheating or inadequate drying performance. Addressing the fault before continued use is the safer approach.

A power reset may temporarily clear the code from the display, but the fault will return quickly if the underlying problem has not been fixed. Because the error requires the thermistor to read above 50 kΩ for only one minute in Run mode, or triggers immediately in diagnostic mode, the code will reappear as soon as the unit attempts to operate normally. A permanent fix requires repairing or replacing the faulty thermistor or wiring.

A knowledgeable DIYer can diagnose and often repair this fault. Start by locating the exhaust thermistor, disconnecting it, and testing its resistance with a multimeter. If the resistance reads very high or shows an open circuit, the thermistor needs replacement. Also check all wiring and connectors along the thermistor circuit for damage or loose connections before ordering parts.

If only the thermistor needs replacement, part costs are typically in the range of $15 to $40, and the repair is straightforward for a DIYer. If a professional technician is needed, total costs including labor can range from $100 to $250 depending on your location and the extent of the diagnosis required. Wiring repairs or control board replacement would increase the cost.
