Light and Fan Switch
This is a dual-pole mechanical plunger switch responsible for cycling both the lighting circuit and the evaporator fan. Failure typically occurs due to contact oxidation or mechanical binding within the plunger housing, leading to unresponsive lighting or 'Door Ajar' alarms. Replacing this granular component restores the circuit logic required for proper fan and light timing.

Switch Spacer/Shim
In integrated units like the 736TC, the tolerance between the door panel and the switch plunger is critical. If the door panel has shifted or the spacer has degraded, the plunger may not fully depress even if the electrical component is functional. This shim ensures the mechanical 'throw' of the door reaches the switch's actuation point.

Door Switch Wire Harness
Though less common, the wiring harness at the hinge point can suffer from work-hardening and eventual fracture due to the repeated bending stress of door opening. If a new switch does not resolve the continuity issue, a break in this harness is the secondary mechanical failure point.
