Maytag Dryer Error Code 01

Error code 01 on a Maytag dryer means the control board has detected a thermistor short condition, where the thermistor's resistance has dropped very low and the sensed temperature has exceeded 200°F for 2 minutes (or 175°F on MDE/MDG6800 and MDG5500 models). This indicates either a real overheating event caused by restricted airflow or a failed thermistor sending a false signal. The dryer will stop operating to prevent damage or a safety hazard. Both the ventilation system and the thermistor itself need to be evaluated.

No, you should not continue running the dryer until the cause of error code 01 is resolved. This code indicates a high-temperature condition that could pose a fire risk, particularly if the root cause is a blocked vent or lint screen. The dryer's control system stops operation specifically to prevent heat-related damage or hazards. Address the airflow and thermistor issues before resuming use.

If the issue is simply a clogged lint screen or accessible vent blockage, the fix is free aside from any vent cleaning tools you may need. Professional vent cleaning services typically range from $80 to $175 depending on duct length and accessibility. If a thermistor replacement is needed, the part itself generally costs between $10 and $40, with professional labor adding $75 to $150. Control board replacement, if required, is significantly more expensive and can range from $150 to $350 or more for parts and labor.

Start by cleaning the lint screen thoroughly and inspecting the entire exhaust vent duct for blockages, kinks, or crushed sections. If the vent system is clear and unobstructed, use a multimeter to test the thermistor's resistance at room temperature. A reading near zero ohms confirms a shorted thermistor that needs to be replaced. If both the vent and the thermistor check out, the control board may require further inspection.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the fault display, but the error will return if the underlying cause has not been corrected. If restricted airflow is causing real overheating, the code will reappear quickly once the dryer runs again. A shorted thermistor will also continue to trigger the fault on every cycle. Resetting without diagnosing and fixing the problem is not a long-term solution.
