Miele Dryer Error Code Rotary Iron LED steady

On a Miele T1576 dryer, a steady Rotary Iron LED indicates that the fan NTC temperature sensor has an open circuit fault. The NTC sensor monitors airflow temperature from the fan, and an open circuit means the control board is receiving no valid signal from it. The dryer stops operation to prevent potential thermal damage. A technician retrieves the specific fault code through Service Mode to confirm the diagnosis.

A simple power cycle or reset will not permanently clear this fault because the control board will re-detect the open circuit in the fan NTC sensor as soon as the dryer attempts to operate. The fault code will return immediately or on the next cycle. The underlying cause, whether a failed sensor, broken wire, or loose connector, must be repaired before the error will clear and stay clear.

Repair costs vary depending on which component is faulty. Replacing a fan NTC sensor is typically a lower-cost repair, with parts and labor generally ranging from around $100 to $250. If the control board is the root cause, costs can range from $250 to $500 or more depending on parts availability and labor rates in your area. Getting a diagnostic visit from a Miele-experienced technician will give you a more accurate estimate before committing to a repair.

A knowledgeable DIYer can start by checking the sensor's wiring harness for visible damage and reseating the connectors, which requires no special tools. However, replacing the fan NTC sensor or diagnosing a control board fault involves disassembly and electrical testing with a multimeter, which is better suited to a technician familiar with the T1576 platform. Attempting repairs without proper diagnosis risks misidentifying the faulty component.

It is not recommended to continue operating the dryer with this fault active. The fan NTC sensor provides the control board with critical temperature data for the airflow path, and without a valid reading the dryer cannot properly regulate heat. Continued use without this sensor functioning could allow thermal conditions to go unmonitored, increasing the risk of overheating or component damage.
