Maytag Dryer Error Code EXHAUST PROBE FAULT

This code means the dryer's control board has detected a problem with the exhaust temperature sensor circuit. The sensor monitors the temperature of air leaving the drum, and when its signal falls outside the expected range, the fault is triggered. The dryer will run without heat for 3 minutes and then shut off all outputs as a safety measure. The issue must be diagnosed and repaired before normal operation can resume.

The dryer's fail-safe mode limits operation to 3 minutes without heat before shutting off, so the risk of overheating is reduced. However, the dryer will not function normally and you should not rely on it for drying loads. It is best to address the fault promptly rather than attempting to repeatedly restart the machine.

If only the exhaust temperature sensor needs replacement, the repair is generally on the lower end of the cost spectrum, with parts typically ranging from $15 to $50 and professional labor adding $75 to $150 depending on your area. If the control board is at fault, parts alone can range from $100 to $300 or more. Getting a diagnostic visit from a technician before committing to parts can help avoid unnecessary expense.

Many of the common causes are accessible to a knowledgeable DIYer. Inspecting the wiring harness, checking connectors for corrosion, and testing the sensor with a multimeter are reasonable first steps. Replacing the exhaust temperature sensor is a relatively straightforward repair if the sensor is confirmed faulty. Control board replacement is more involved and may be better suited to a professional technician.

A reset may temporarily clear the fault code, but if the underlying problem with the sensor or wiring has not been corrected, the fault will return. The dryer's control board will detect the same out-of-range signal on the next cycle and trigger the code again. A lasting fix requires diagnosing and repairing the actual cause.
