Maytag Dryer Error Code 2

Error code 2 means the control board detected an open thermistor circuit, where the thermistor's resistance reading is too high for the board to interpret as a valid temperature signal. The thermistor is the sensor that monitors heat inside the dryer. The fault can stem from a genuinely failed sensor, but cold room temperatures, a stuck vent damper, or a loose wiring connector are just as likely and easier to fix first.

Running the dryer with code 2 active is not recommended. The thermistor is the primary temperature-monitoring sensor, and without a valid reading the control board cannot regulate heat accurately. This creates a risk of overheating your laundry or the internal components. Resolve the fault before resuming normal use.

Yes, cold weather is a documented trigger for code 2. The thermistor's resistance increases as temperature drops, and below 50°F / 10°C the resistance can climb high enough that the control board flags it as an open circuit. This is especially common when an exterior vent damper is stuck open, allowing cold outside air to flow through the vent path and keep the thermistor reading abnormally cold even after the dryer warms up. Addressing the damper and room temperature is the first step before any parts replacement.

Begin by checking the ambient room temperature. If the laundry area is below 50°F / 10°C, warm it up and clear the code. Next, inspect the exterior vent damper for ice, debris, or physical damage keeping it open. Then check the thermistor wiring connector for loose or corroded terminals and reseat it firmly. If all three checks pass and the code returns, test the thermistor's resistance with a multimeter and replace it if the reading is out of spec for your model.

If the cause is low room temperature, a stuck vent damper, or a loose wire terminal, the fix costs nothing beyond your time. A replacement thermistor typically runs between $10 and $30 for the part alone. If you hire a technician for the diagnosis and thermistor replacement, expect a total service call cost in the range of $75 to $150 depending on your area and the technician's rates.
