Samsung Dryer: drum not turning

Professional Repair Guide

What is this symptom?

If your Samsung dryer powers on but the drum isn't turning, you may hear the motor humming. This issue often indicates a broken drive belt, faulty door switch, or other mechanical failure. Ensure the door is fully closed, as this can sometimes prevent the drum from rotating. Explore DIY solutions or professional repairs to restore functionality.

Urgency: Medium

Important Tips for Samsung Models

  • Child Lock feature may prevent cycle start and drum spin; disable per manual if icon lit.

Part: Door switch/sensor

Control board or electronic failure
