How to Fix / Troubleshooting

Safety first: Do not increase force to compensate for a door that is hard to move by hand. Fix mechanical issues first.

Check door balance:

Disconnect the opener using the emergency release.
Lift the door halfway and release. If it falls or rises quickly, springs need professional adjustment.

Inspect and correct binding:

Check tracks for bends or misalignment. Loosen mounting brackets slightly, tap tracks into alignment, and retighten.
Replace cracked or seized rollers.

Adjust down force:

Locate the DOWN force adjustment on the Decko opener.
Increase slightly (1/8–1/4 turn) and test closing. Repeat until the door closes reliably but still reverses when it hits a 2x4 board on the floor.
