Maytag Dryer Error Code OPEN EXHAUST TEMPERATURE PROBE

This error code means the control board has detected that the exhaust temperature sensor probe circuit is either open (no signal) or shorted (out-of-range signal). The exhaust temperature probe is a thermistor that monitors the heat of the air leaving the drum. The board uses this data to regulate drying temperature, and when the circuit fails, it logs this fault to prevent unsafe operation.

It is not recommended to continue using the dryer while this error is active. The exhaust temperature probe is part of the heat regulation system, and without a reliable reading from this sensor, the control board cannot properly manage heating cycles. Running the dryer in this condition could result in overheating or inadequate drying performance.

Repair costs vary depending on the cause. If only a connector needs to be reseated, there may be no parts cost at all. A replacement exhaust temperature probe typically costs in the range of $15 to $50 for the part, while a new control board can range from $100 to $250 or more. If you hire a technician, expect to add labor charges on top of the parts cost.

In many cases, yes. Start by unplugging the dryer and checking the J3 connector on the control board for a loose or corroded connection, then reseat it firmly. If the connector is secure, use a multimeter to test the resistance of the exhaust temperature probe. A failed probe is a relatively straightforward part replacement for someone comfortable working inside a dryer.

A power reset may temporarily clear the code if the fault was caused by a momentary loose connection, but the error will return if the underlying problem is not corrected. If the probe itself has failed or the wiring is damaged, the fault code will reappear as soon as the dryer attempts to run a cycle. The root cause must be diagnosed and repaired for the code to clear permanently.
