Main Power Control Board
The Main PCB contains the switch-mode power supply (SMPS) that regulates voltage for the entire unit. If the step-down transformer or the capacitors on the DC rail fail, the user interface will not illuminate, resulting in a 'dead' state. This is often caused by localized heat fatigue or power surges on the control circuit.

Thermal Fuse
The thermal fuse is a critical safety device located on the blower housing that monitors exhaust temperature. If airflow is restricted by lint buildup, the internal temperature exceeds the fuse's threshold (typically around 167°F), causing the internal link to melt. This breaks the circuit to the drive motor, preventing the dryer from initiating a cycle.

Door Switch
The door switch acts as a mechanical interlock to ensure the drum does not rotate while the door is open. If the internal leaf spring fails or the copper contacts become pitted and carbonized, the control board will not receive the 'closed' signal, effectively inhibiting the start relay regardless of user input.
