What 17 means on a Maytag dryer

Error code 17 on a Maytag dryer indicates the control board has detected a possible short circuit in the thermistor circuit. The thermistor is a temperature-sensing resistor that feeds real-time temperature data to the control board throughout the drying cycle. When the board reads a resistance value that falls below the expected range, it interprets this as a short and throws code 17. This typically points to a failed thermistor, damaged wiring in the thermistor circuit, or a connector that has shorted to ground.

For homeowners, the thermistor is a small sensor, usually mounted on or near the exhaust duct or drum housing, that tells your dryer how hot it is inside. When it shorts, the dryer can no longer trust its temperature readings. Rather than risk overheating, the control board shuts the cycle down and displays this code to flag the problem before it causes damage.

This code is specific to the thermistor circuit and should not be confused with open-circuit thermistor faults. A shorted thermistor typically sends an abnormally low resistance signal rather than no signal at all, which is an important distinction when diagnosing the circuit with a multimeter.

Common causes of 17

  1. 01

    Failed thermistor (shorted internally)

    Part replacement

    The thermistor itself can fail internally, causing its resistance to drop far below normal operating range. This is the most common trigger for code 17 and requires replacing the thermistor component.

  2. 02

    Pinched or damaged thermistor wiring harness

    Part replacement

    If the wiring between the thermistor and control board is pinched, chafed, or has worn insulation, two conductors can contact each other and create a short. Inspecting the harness along its full routing may reveal visible damage.

  3. 03

    Corroded or shorted thermistor connector

    Wiring / connection

    Moisture or heat exposure can corrode the connector terminals at the thermistor plug, causing two pins to bridge and produce a short circuit reading at the control board.

  4. 04

    Faulty control board

    Part replacement

    If the thermistor and its wiring both test within normal specifications, the control board itself may be misreading the circuit due to a damaged input stage. This is the least likely cause and should only be considered after the thermistor and harness have been ruled out.

Frequently asked questions about 17

What does error code 17 mean on a Maytag dryer?
Error code 17 means the control board has detected a possible short in the thermistor circuit. The thermistor is the temperature sensor that monitors heat inside the dryer drum and exhaust path. A shorted thermistor sends an abnormally low resistance signal to the board, which triggers the code and halts operation.
How do I fix error code 17 on a Maytag dryer?
Start by unplugging the dryer and locating the thermistor, which is typically mounted near the exhaust duct or drum outlet. Disconnect the thermistor and test its resistance with a multimeter. A shorted thermistor will read near zero ohms instead of the specified range, and replacing it will usually clear code 17. If the thermistor tests fine, inspect the wiring harness for pinched or damaged insulation before considering a control board replacement.
Is it safe to use my Maytag dryer when error code 17 is showing?
You should not continue using the dryer while code 17 is active. The thermistor is how the dryer monitors internal temperature, and a shorted sensor means the control board cannot accurately detect overheating conditions. Running the dryer in this state removes a key safety layer and could result in heat damage to clothing or internal components.
How much does it cost to fix error code 17 on a Maytag dryer?
If the thermistor itself is the problem, the part typically costs between $10 and $30, and replacing it is a repair most DIYers can complete with basic tools in under an hour. If the wiring harness needs repair or replacement, add $20 to $60 in parts. A control board replacement is the most expensive scenario, often ranging from $100 to $250 for the part alone, and professional labor will add to that total.
Can I test the thermistor myself to diagnose code 17?
Yes. Unplug the dryer, disconnect the thermistor connector, and use a multimeter set to measure resistance. At room temperature, most Maytag dryer thermistors should read somewhere in the range of 10,000 to 50,000 ohms depending on the specific model. A reading near zero confirms a short, meaning the thermistor needs to be replaced. Check your model's technical sheet for the exact resistance specification if you want to verify against factory values.
