What Rotary Iron & Hand Iron LEDs steady means on a Miele dryer

On the Miele T1576 dryer, the simultaneous steady illumination of both the Rotary Iron and Hand Iron LEDs signals a short circuit condition in the fan NTC temperature sensor. The NTC (Negative Temperature Coefficient) thermistor is responsible for monitoring the air temperature within the fan circuit. Under normal operation, the sensor's resistance decreases predictably as temperature rises, providing the control board with continuous thermal feedback. A short circuit in this sensor causes resistance to drop to near zero, presenting the control board with a temperature reading that is falsely extreme or completely invalid, triggering this fault indication.

The fan NTC sensor short circuit is distinct from an open circuit failure. A short circuit means the sensor circuit has an unintended low-resistance path, which can occur within the sensor itself or along the wiring harness connecting it to the control board. The control board detects this abnormal signal and flags the fault rather than allowing the dryer to operate with unreliable thermal data. This is a protective measure, as accurate temperature monitoring is critical to preventing overheating and ensuring proper drying cycles.

Diagnosing this fault begins in Service Mode. With the selector turned to the Woolens position and Start pressed, the stored fault code can be retrieved. From there, technicians should measure resistance across the fan NTC sensor terminals to confirm a short circuit reading. Wiring harness integrity between the sensor and the control board should also be inspected for pinched, chafed, or heat-damaged insulation that could create an unintended short to ground.

Common causes of Rotary Iron & Hand Iron LEDs steady

  1. 01

    Failed fan NTC temperature sensor

    Part replacement

    The NTC thermistor itself has developed an internal short circuit, causing its resistance to collapse to near zero. This can be confirmed by measuring resistance across the sensor terminals, which will read far outside the expected range for the current temperature.

  2. 02

    Damaged wiring harness to the fan NTC

    Part replacement

    Heat exposure, vibration, or routing issues can cause the insulation on the wiring between the fan NTC sensor and the control board to chafe or melt, creating a short to ground or between conductors. Inspect the full length of the harness for visible damage or pinch points.

  3. 03

    Corroded or contaminated sensor connector

    Wiring / connection

    Moisture or lint buildup inside the sensor connector can create a conductive bridge between terminals, mimicking a short circuit. Disconnecting and inspecting the connector for corrosion, discoloration, or debris is an important early diagnostic step.

  4. 04

    Control board fault misreading sensor signal

    Part replacement

    In less common cases, the input circuit on the control board that reads the fan NTC signal can fail, causing it to interpret a normal sensor as shorted. This is typically diagnosed only after the sensor and wiring have been confirmed to be in good condition.

Frequently asked questions about Rotary Iron & Hand Iron LEDs steady

What does Rotary Iron & Hand Iron LEDs steady mean on a Miele dryer?
This LED combination indicates a short circuit fault in the fan NTC temperature sensor, and it applies specifically to the Miele T1576 model. The fan NTC is a thermistor that monitors air temperature near the fan during operation. When the control board detects a short circuit in this sensor circuit, it stores the fault and halts normal operation to protect the appliance from running without reliable temperature data.
How do I access the fault code to confirm this error on my Miele T1576?
To retrieve the fault code, enter Service Mode on the dryer, rotate the program selector to the Woolens position, and press the Start button. The stored fault code will then be displayed, allowing you to confirm that the fan NTC short circuit is the active fault before beginning component-level diagnostics.
Can I reset the dryer to clear this error and continue using it?
Resetting the dryer will not reliably clear this fault because the short circuit condition in the fan NTC sensor will cause the error to return as soon as the control board performs its sensor checks. The underlying electrical fault in the sensor or wiring must be repaired before the dryer will operate normally. Attempting to bypass or ignore this fault risks running the dryer without valid thermal monitoring.
Is it safe to use my Miele dryer while this error is active?
It is not recommended to operate the dryer while this fault is present. The fan NTC sensor provides critical temperature feedback that the control board uses to regulate heat during drying cycles. With a short circuit in this sensor, the dryer cannot accurately monitor fan area temperatures, which removes an important safeguard against overheating. The appliance should remain out of service until the fault is diagnosed and repaired.
How much does it cost to fix a fan NTC sensor short circuit on a Miele dryer?
Repair costs vary depending on whether the fault is in the sensor itself, the wiring harness, or the control board. If only the fan NTC thermistor needs replacement, parts and labor costs typically range from around $100 to $250. If the control board is involved, costs can rise significantly, often falling in the range of $300 to $600 or more depending on parts availability and local labor rates.
