Pick the problem, then answer yes or no.

Possible outcomes

My door won't open

Broken spring. Stop using the door and don't lift it by hand. The spring must be replaced. → service
No power. Check the outlet, breaker and any GFCI outlet. If there's power and still no lights, the logic board may have failed. → service
The motor runs but can't move the door: a stripped gear, a disconnected trolley or a heavy, unbalanced door. → service
A remote problem: replace the battery, turn off lock mode and reprogram the remote. → service
The opener has power but doesn't respond to controls. Likely a logic board or wall-control wiring fault. → service

My door won't close

Safety sensors. Clean the lenses, clear the path and realign them until both lights are steady. → service
Force or travel limits, or a door that's binding. Have the balance and settings checked rather than turning up the force. → service
The door is off track or a cable has failed. Stop using it and keep clear. → service
Check that lock or vacation mode is off and the remote battery is good. If so, the opener needs a diagnosis. → service

My door is noisy

Usually dry hinges, rollers or springs. Lubricate them with a garage door spray. If it persists, rollers may be worn. → service
Worn drive gear or chain. Have the opener checked before it strips completely. → service
Loose hinges, track bolts or a slack chain. Tighten hardware and have the door's balance checked. → service
Rumbling usually means worn roller bearings. Sealed nylon rollers are much quieter. → service

My door reverses on its own

Safety sensors are misaligned, dirty or catching sun glare. → service
The door is binding or too heavy, or the force setting is off. Get the balance checked first. → service
The close travel limit is set too low, so the opener thinks it hit something. Adjust the down limit. → service

My remote or keypad doesn't work

The opener itself isn't responding, so this isn't a remote problem. → service
Fixed! Remote batteries usually last 1 to 2 years. → service
Lock mode is on. Press and hold the lock button to turn it off. → service
Reprogram the remote with the opener's learn button. Check that the remote is compatible with the learn button's color. → service

The opener runs but the door doesn't move

Reconnect the trolley: run the opener until it clicks back into the carriage, or follow your manual. → service
Broken spring. Don't run the opener. Replace the spring first. → service
Likely a stripped drive gear or sprocket inside the opener. → service

Safety: if a spring or cable is broken, or the door is crooked or off its tracks, stop using it and keep clear. These parts are under high tension.
