Opener humming but the door won’t move? Remote quit? Door goes down then pops right back up? Most opener problems are a quick fix.
Common opener problems
- Remote or keypad not working
- Motor runs but the door doesn’t move
- Door reverses before it closes
- Safety sensors out of line
- Opener clicks or hums and does nothing
- Loud grinding from the motor
- Old opener that’s done
Sensors are the usual suspect
If the door starts down and goes right back up, check the two little sensors near the floor on each side of the door. If one got bumped, is dirty, or has a loose wire, the opener thinks something is in the way. A blinking light on the sensor or the opener is a good clue.
When the motor runs but nothing moves
That usually means a stripped gear inside the opener or a broken spring on the door itself. Plastic drive gears wear out, and Florida garages get hot enough to speed that up. If the door is heavy to lift by hand, the problem is the spring, not the opener. See spring repair.
Repair or replace the opener?
Gears, sensors, remotes, keypads and logic boards can all be replaced. If the opener is old, loud, missing modern safety features, or keeps breaking, a new one usually makes more sense. Newer openers are quieter, and many have battery backup and phone control.
Opener questions
My remote stopped working. Is the opener bad?
Not always. Try a new battery first. If the wall button works but the remote doesn’t, it’s usually the remote or its programming.
Can you install a new opener on my existing door?
Yes, as long as the door is balanced and in good shape. The tech will check the door first so the new opener isn’t fighting it.
