Dryer interior light and display work, but there is a strong electrical buzzing or humming noise and the drum does not move.

Safety first: Unplug the dryer immediately to prevent motor damage. Do not repeatedly try to start a stalled motor.

• Check drum movement: Rotate the drum by hand. If stiff, look for obstructions or bearing issues.
• Inspect blower: Access the blower housing and check for objects (e.g., coins, buttons) jamming the fan.
• Test and replace capacitor: Locate the motor capacitor, discharge it safely, and test with a capacitance meter. Replace if the value is significantly below the rating or if it is open/shorted.
• Assess motor condition: If the drum and blower are free and the capacitor is good, the motor may be defective and should be replaced.
