Decko opener runs but door only moves a few inches then stops without reversing.

Safety first: Keep clear of the door while testing. Disconnect power before adjusting mechanical limit components.

Re-run setup (if model supports auto-learn):

• Some Decko models have a setup or program button sequence to relearn open/close positions. Refer to your manual for the exact procedure (often holding the LEARN button until LEDs flash, then running a full open and close cycle).

Manual limit adjustment:

• Locate the UP and DOWN limit screws or cams on the opener head or rail.
• Increase the separation between open and close limits by turning each screw in small increments and testing travel.
• Ensure the door can reach fully open and fully closed positions without hitting the stops too early.

If the opener consistently stops at the same short distance despite correct limit settings, the travel sensor or control board may be defective.
