CAME garage door opener operates but the door stops short of fully open position, leaving a gap

Safety first: Use a stable ladder and avoid working near moving parts while the opener is running.

Steps:

• Measure gap: Note how far short the door stops.
• Adjust mechanical cam: On cam‑based CAME units, rotate the open cam slightly to allow more travel, then test.
• Reprogram open limit: On electronic models, enter programming mode and reset the open limit to the fully open position.
• Check for obstructions: Ensure nothing is physically stopping the door from reaching full open.

After adjustment, run several cycles to confirm consistent full opening.
