Cooling Fan Motor
The tangential cooling fan is designed to exhaust hot air from the cabinet and cool the internal electronics plenum via forced convection. If the motor bearings fail or the windings short, the lack of airflow leads to a rapid increase in ambient temperature around the control area. The thermal fuse reacts to this convection failure by opening the circuit to prevent catastrophic thermal damage.

Thermal Cut-out (High Limit)
This is the actual component that has tripped; it is a non-resettable safety device that physically breaks the electrical path when it reaches its calibrated temperature limit. Once the underlying airflow or relay issue is corrected, this component must be replaced to restore power to the oven's control system. It acts as the final line of defense against thermal runaway.

Main Power Control Board
A mechanical failure of the heating element relay on this board can result in the relay sticking in the 'closed' position. This causes the heating elements to remain energized regardless of the thermostat's commands, leading to heat levels that exceed the safety thresholds monitored by the thermal fuse.
