Maytag Dryer Error Code SHORTED THERMISTOR PROBE

The SHORTED THERMISTOR PROBE error on a Maytag dryer indicates a fault within the S.A.F.E. (Sensing Appliance For the Environment) system, specifically involving the thermistor probe used to monitor temperature. A thermistor is a resistive temperature sensor whose resistance changes predictably with temperature. When the control board detects an abnormally low resistance reading from the probe circuit, it interprets this as a short circuit condition, meaning the sensor or its wiring has developed an unintended electrical path that bypasses normal signal behavior. This prevents the control from receiving accurate temperature data.

The S.A.F.E. system is designed as a safety layer to protect against thermal runaway and fire risk. When this error triggers, the control immediately enters S.A.F.E. SYSTEM DISABLED mode, which effectively shuts down the dryer's ability to operate under normal parameters. This is an intentional failsafe response: the system cannot safely regulate heat without a functioning thermistor probe, so it disables itself rather than risk overheating.

The most likely physical causes include damaged insulation on the thermistor wiring harness, a pinched or crushed wire that has created a short to ground, a failed thermistor probe with internal short, or moisture intrusion into the connector. Because the control immediately disables itself upon detecting this fault, the dryer will not resume normal operation until the underlying short is identified and corrected through inspection, testing, or component replacement.
