Dryer display and buttons work, but the drum does not rotate and there is no motor sound

Safety first: Unplug the dryer before accessing the motor or control board.

• Check drum by hand: Rotate the drum manually to ensure it is not mechanically jammed.
• Inspect motor wiring: Access the motor and check that all connectors are firmly attached and wires are intact.
• Test motor windings: Use a multimeter to measure resistance across the motor windings. Replace the motor if windings are open or shorted.
• Check motor thermal protector: Some motors have an internal thermal cut-out. If accessible and open, allow the motor to cool and test again. Replace the motor if the protector does not reset.
• PCB relay: If the motor and wiring are good, the motor relay on the PCB may be faulty and should be replaced by a technician.
