Door Interlock Switch
The mechanical plunger experiences physical fatigue or internal contact carbonization over time, preventing the electrical circuit from completing when the door is opened. This results in a failure to trigger the interior lighting and can cause the dispenser logic to remain locked. This is the most direct mechanical failure related to the user's reported symptom.

LED Lighting Power Supply Transformer
Statistically common in Monogram units where the user perceives a 'door switch' issue because the lights won't turn on. This transformer steps down 120VAC to 13V/50V for the LED arrays; thermal stress in the lower machine compartment leads to primary winding failure, resulting in no light output regardless of switch state.

Main Power Control Board
The control board serves as the logic hub that interprets the 5V/12V DC signal from the door switch. Solder joint fractures or capacitor degradation on the logic rail can prevent the board from recognizing the transition from 'closed' to 'open,' effectively neutralizing the door switch's function.
