Thermal Fuse
This is a one-time safety device located on the blower housing that monitors exhaust temperature. If the internal airflow is restricted by lint, the resulting heat spike causes the internal conductive element to melt, opening the circuit to the motor. Once this thermal threshold is breached, the dryer is electromechanically locked out from starting until the component is replaced.

Door Switch
The door switch serves as the primary safety interlock to ensure the drum does not rotate while the cabinet is accessible. Over time, the internal spring mechanism can fatigue or the copper contact points can suffer from carbon tracking (arcing), preventing the completion of the start circuit even when the door strike is mechanically engaged.

Dryer Drive Belt
Whirlpool units often utilize a belt-tensioner safety switch. If the multi-ribbed belt snaps due to friction-induced heat or mechanical wear, the idler pulley arm drops, which mechanically toggles a microswitch. This opens the motor circuit to prevent the motor from spinning without the resistance of the drum, which would otherwise lead to centrifugal damage or motor overheating.
