What AXIAL PROBE FAULT means on a Maytag dryer

The AXIAL PROBE FAULT on a Maytag dryer indicates a problem detected in the axial temperature sensor circuit. The axial probe is a thermistor-based sensor positioned to monitor airflow temperatures within the dryer drum or exhaust pathway. When the control board reads a signal from this sensor that falls outside the expected range, whether due to an open circuit, a short, or an out-of-range resistance value, it logs this fault and begins a protective shutdown sequence.

The dryer's response to this fault is specific and worth understanding for diagnostic purposes. Once the fault is triggered, the unit will continue to run for approximately 3 minutes but without producing any heat. After that 3-minute window, the control board shuts off all outputs entirely, effectively disabling the dryer until the underlying issue is resolved. This behavior is a thermal protection strategy designed to prevent overheating or fire risk from an unmonitored heating system.

The most productive starting point is a physical inspection of the axial temperature sensor and its associated wiring harness. Technicians should look for damaged insulation, corroded connector pins, or broken wires that could cause an intermittent or complete loss of signal. If the wiring appears intact, the sensor itself should be tested for proper resistance values using a multimeter. A failed sensor will typically read open or far outside the manufacturer's specified resistance range for a given temperature.

Common causes of AXIAL PROBE FAULT

  1. 01

    Failed axial temperature sensor

    Part replacement

    The axial probe thermistor itself may have burned out or failed internally, causing it to read an open circuit or an out-of-range resistance value. Testing the sensor with a multimeter will reveal if it has failed and needs replacement.

  2. 02

    Damaged or disconnected wiring harness

    Wiring / connection

    The wiring connecting the axial probe to the control board can become frayed, pinched, or disconnected over time due to vibration or heat exposure. Inspect the full length of the harness and check connector pins for corrosion or looseness.

  3. 03

    Corroded sensor connector

    Wiring / connection

    Moisture or lint buildup at the sensor's electrical connector can cause high resistance or intermittent contact, which the control board interprets as a sensor fault. Cleaning or replacing the connector may resolve the issue.

  4. 04

    Control board fault

    Part replacement

    If the sensor and wiring both test within spec, the control board's input circuit for the axial probe may have failed. This is less common but should be considered after ruling out the sensor and wiring.

  5. 05

    Loose or intermittent sensor connection

    Wiring / connection

    A connector that is not fully seated at the sensor or at the board can cause the signal to drop in and out, triggering the fault even when the sensor itself is functional. Reseating all connections in the circuit is a quick first check.

Frequently asked questions about AXIAL PROBE FAULT

What does AXIAL PROBE FAULT mean on a Maytag dryer?
The AXIAL PROBE FAULT code means the dryer's control board has detected a problem in the axial temperature sensor circuit. This sensor monitors temperatures during the drying cycle, and when its signal falls outside the expected range, the dryer enters a protective mode. The unit will run without heat for about 3 minutes and then shut off all outputs until the issue is corrected.
Can I fix the AXIAL PROBE FAULT myself?
A knowledgeable DIYer can begin by inspecting the axial temperature sensor and its wiring harness for visible damage, corrosion, or loose connectors. If the wiring looks intact, testing the sensor's resistance with a multimeter can confirm whether the sensor has failed. Replacing a thermistor sensor is a manageable repair for someone comfortable working with appliance components, but if the control board is the source of the fault, professional diagnosis is recommended.
Is it safe to keep using my Maytag dryer with the AXIAL PROBE FAULT showing?
The dryer is designed to disable itself after a short period when this fault is active, so continued use is not possible in the normal sense. Attempting to repeatedly restart the dryer to force cycles without resolving the fault is not advisable, as the temperature monitoring system is compromised. The safest course is to stop using the dryer until the sensor circuit is inspected and repaired.
Will resetting the dryer clear the AXIAL PROBE FAULT?
A simple power reset may temporarily clear the fault code, but the error will return quickly if the underlying problem in the axial sensor circuit has not been fixed. The control board will detect the abnormal sensor signal again within the next cycle and re-enter the shutdown sequence. A reset alone is not a repair and should not be relied upon as a solution.
How much does it cost to repair the AXIAL PROBE FAULT on a Maytag dryer?
Repair costs depend on which component has failed. If only the axial temperature sensor needs replacement, parts typically range from around $20 to $60, with professional labor adding $80 to $150 or more depending on the service provider. If the wiring harness or control board is the root cause, total repair costs can range from $150 to $350 or higher. Getting a diagnostic visit from a technician before purchasing parts is a good way to avoid unnecessary expenses.
