What is a common problem with elevator door operators?

Misalignment that causes malfunction is a common issue with elevator door operators because it directly affects their ability to function correctly. When elevator doors are misaligned, they may not open or close properly, leading to operational failures. This can occur due to various reasons, such as wear and tear on the door tracks, improper installation, or damage from impacts. Misalignment not only disrupts normal operation but also poses safety risks for passengers, as doors may not detect obstacles correctly or may fail to close entirely.

Addressing misalignment typically involves adjusting the positioning of the doors or tracks, ensuring that the sensors and other mechanisms can operate effectively. Regular maintenance checks are essential to identify and correct such misalignments before they lead to more significant issues.
