Maytag Dryer Error Code EXHAUST HIGH TEMP FAULT

It means the dryer's control system detected a steady, gradual temperature increase at the exhaust sensor that reached approximately 20 degrees above the maximum allowable set point. The dryer responds by running without heat for up to 3 minutes to cool down, then shuts off completely. This fault points to a problem with airflow restriction or a temperature regulation component. The dryer will not operate normally until the cause is corrected.

No, you should not continue operating the dryer until the fault has been diagnosed and corrected. The EXHAUST HIGH TEMP FAULT indicates the dryer reached a dangerously high temperature, which is a fire risk, particularly if the cause is a restricted exhaust duct with lint accumulation. The dryer's built-in shutdown response is a protective measure, not a permanent solution.

Repair costs vary depending on the cause. Clearing a blocked exhaust duct yourself costs nothing beyond your time, while professional duct cleaning services typically range from $75 to $150. Replacing a high-limit thermostat or temperature sensor generally runs between $20 and $80 in parts, with labor adding $100 to $200 if a technician is doing the work. A failed heating element or gas valve component will cost more, with total repair estimates ranging from $150 to $400 or higher depending on your specific model and labor rates.

Resetting the dryer by unplugging it or cycling the breaker may temporarily clear the fault code, but the fault will return if the underlying cause is not fixed. The control board is designed to detect the same gradual temperature rise pattern and will trip the fault again under the same conditions. Address the root cause first, such as clearing a blocked vent or replacing a failed thermostat, before relying on a reset.

Start by cleaning the lint screen and inspecting the full length of the exhaust duct for blockages, kinks, or a stuck exterior vent flap. If airflow is clear, the next step is to test the high-limit thermostat and exhaust temperature sensor for correct operation. A failed thermostat or sensor will need to be replaced. If those components test correctly, inspect the heating element or gas valve for a fault that is causing continuous heat output.
