How would you diagnose a gear that seems stuck due to door misalignment?

• A. Replace the entire gear assembly immediately.
• B. Ignore door misalignment and continue.
• C. Inspect door alignment, verify interlocks and limit switches, and check for binding in door or hinge.
• D. Disable door interlocks to force operation.

Answer: (C)

When a gear seems stuck, the door system is often the real culprit. If the doors are misaligned, they can rub against the gear or frame and physically prevent full travel, and they can also cause interlocks or limit switches to sense the door in the wrong position and stop the gear from moving. So the right way to diagnose is to inspect the door alignment first, making sure the doors sit correctly in their tracks, latch properly, and clear any obstructions that could cause binding. Next, verify that the door interlocks and the limit switches are functioning and reading the door position correctly, since a faulty sensor can keep the gear inhibited even if the mechanism is otherwise fine. Finally, check for binding in the door or hinge area—such as rough hinges, misaligned pivots, or debris—that could physically impede movement. These steps target the most common cause of a stuck gear without unnecessarily replacing parts or compromising safety. Replacing the entire gear, ignoring the misalignment, or disabling interlocks would not address the actual fault and could create unsafe conditions.
