Start with the sensors. Then the track. Then the settings.
A door stuck open leaves the house exposed, so this is the fault we get called about most in the evenings. Run these checks in order.
Two sensors sit about six inches off the floor on either side of the opening. They must see each other. Bikes, bins, laundry baskets, a stray snow shovel, spider webs, low winter sun and a nudged bracket will all break the beam. Clean the lenses and adjust until both indicator lights are steady rather than blinking.
Walk both tracks from floor to ceiling and look for debris, a bent section, or a roller that has jumped out. If the door is crooked or jammed at an angle, stop using the opener entirely — that is an off-track door and forcing it bends panels.
If someone has thrown the slide lock, the door will not travel. If the emergency release cord has been pulled, the trolley is disconnected and the motor will run happily while nothing moves. Pull the cord toward the door and run the opener to re-latch.
If the door closes fully then bounces straight back up, the opener believes it has hit an obstruction. The down-limit or close-force setting has drifted, usually after a temperature swing. The adjustment is on the motor unit, but do not crank the force up to force the door shut — that disables the safety that protects children and pets.
A Connecticut classic. Water runs under the door, freezes to the slab and glues the bottom seal down. The opener senses the resistance and reverses. Break the ice, clear the channel, and check the seal is still flexible.
If the door closes from the wall button but not the remote, it is a remote, battery or antenna issue rather than a door issue.
Call the same day if you see a gap in the spring coil, a hanging cable, a bent track, a crooked door, or if the door has dropped fast at any point. Those are load-bearing failures, not settings. We run 24 hour callouts across Connecticut precisely because a door stuck open cannot wait for Monday.
