Thermal Fuse
This is a safety device located on the blower housing. If the dryer overheats due to a restricted exhaust vent or lint buildup, the fuse blows to cut power to the motor. Once blown, the dryer will not start or rotate, and the fuse must be replaced as it cannot be reset.

Dryer Door Switch
The door switch confirms the door is fully closed before allowing the motor to engage. If the plastic plunger is broken or the internal contacts have failed, the control board will not initiate the start sequence even if the door appears shut.

Main Power Control Board
The main PCB contains the motor relay. If the relay fails or the solder joint cracks, the board cannot send the 120V signal to the drive motor. This is suggested only if the thermal fuse and door switch test positive for continuity.
