Dryer Door Switch Assembly
The door switch is a primary safety interlock. If the internal contact fails or the plastic actuator breaks, the control board will not receive the 'closed' signal, which prevents the start relay from engaging the motor. This is a common failure point that results in the control panel lighting up but the unit failing to initiate the drum rotation.

Dryer Thermal Fuse
The thermal fuse is a non-resetting safety device located on the blower housing. If the dryer detects a restricted vent (FlowSense) or excessive heat, the fuse blows to cut power to the motor. Once blown, the dryer will appear to power on, but the motor will not start when the 'Start' button is pressed.

Main Electronic Control Board
If the door switch and thermal fuse test positive for continuity, the issue likely resides in the main PCB's motor relay. The source data mentions 'EE PROM Error' and 'Bad control board' as causes for communication failures; a faulty relay on the board will fail to send the 120V signal to the motor despite user input.
