What to do if my Royal Sovereign RTHD-431SS Dryer does not start?

If your Royal Sovereign Dryer isn't starting, first, check the power supply to the unit and make sure the ON/OFF switch is properly set. If the power supply is fine, the issue might be a defective sensor, which would require replacing the IR sensor. Another possible cause is a defective motor.
