Elevator Mechanic Practice Exam

Which component should be checked if the elevator car doors are not aligned properly?

1. Motor assembly

2. Door tracks

3. Control panel

4. Car door sill height

The correct answer is: Car door sill height

When dealing with improperly aligned elevator car doors, the best component to check is the car door sill height. The car door sill refers to the bottom edge of the car door frame, and if it is not at the appropriate height, it can lead to misalignment of the doors. Proper height ensures that when the doors close, they meet at an even level, allowing for smooth operation and safety. Misalignment can cause issues with the door closing mechanism and can lead to dangerous situations if the doors are improperly positioned. Other components, while potentially related to elevator operation, do not directly influence the alignment of the car doors. The motor assembly primarily drives the elevator's movement, the door tracks guide the movement of the doors but are less likely to cause misalignment on their own, and the control panel is responsible for the elevator's operation but does not physically impact door alignment. Thus, checking the car door sill height is essential for addressing the issue of door alignment.
