Maytag Dryer Error Code OPEN THERMISTOR PROBE

This error means the control board cannot detect a valid signal from the S.A.F.E. system thermistor probe, indicating an open circuit. The S.A.F.E. system is a built-in fire detection feature that monitors dryer temperatures, and when its thermistor is disconnected or fails, the dryer enters S.A.F.E. SYSTEM DISABLED mode and will not operate normally. The fault is caused by a disconnected connector, a broken wire, or a failed thermistor probe.

No, you should not use the dryer while this error is active. The S.A.F.E. system thermistor is a fire-prevention component designed to detect dangerous overheating, and the dryer automatically disables itself when the probe is non-functional. Running the dryer without this safety system in place could allow an overheating condition to go undetected.

If the fix is simply reseating a disconnected connector, there is no parts cost involved. If the thermistor probe itself has failed, the replacement part typically costs in the range of $15 to $50 depending on the specific model, with additional labor costs if a technician performs the repair. A service call from a professional technician generally runs between $100 and $200 including diagnosis and basic repairs.

A knowledgeable DIYer can attempt this repair by first inspecting and reseating the thermistor probe wiring connector, then testing the probe for continuity with a multimeter. If the probe reads open, it will need to be replaced. If the probe tests fine but the error persists, the wiring harness should be traced for damage. Always unplug the dryer before inspecting any internal components.

No, resetting the control will not clear this error unless the underlying fault is corrected first. The control checks the thermistor circuit on startup and will re-enter S.A.F.E. SYSTEM DISABLED mode immediately if it detects an open circuit. The thermistor probe connection must be restored or the probe itself replaced before the error will clear.
