Garage Door Symptoms & Fixes
Direct answers for the most common garage door problems. Each guide has likely causes, DIY checks, when to call a pro, and a typical price range.
Garage door wont close all the way?
If your garage door won't close all the way, the cause is almost always misaligned photo-eye sensors, an incorrect force-limit setting on the opener, or debris under the door.
Garage door reverses when closing?
When a garage door reverses while closing, the opener's safety system has detected an obstruction.
Garage door stuck open?
If your garage door is stuck in the open position, the cause is almost always a broken torsion spring, snapped lift cable, opener failure, or sensor blockage preventing close.
Garage door making loud noise?
A loud garage door is almost always caused by worn-out steel rollers, missing lubrication, loose hardware, or a chain-drive opener.
Garage door wont open with remote?
If your garage door remote stops working, try fresh batteries first.
Garage door cable came off?
If your garage door cable has come off the drum or snapped, stop using the door immediately.
Garage door wont open at all?
If your garage door will not open at all, the most common cause is a broken torsion spring (you often hear a loud bang when it snaps).
Garage door is off track?
A garage door comes off track when a roller leaves the track, usually from a broken cable, a snapped roller, or a vehicle bump.
Garage door motor runs but the door wont move?
If the opener motor runs but the door does not move, the trolley is usually disconnected from the door (red release cord pulled), the opener's drive gear is stripped, or the belt or chain has broken.
Garage door opens or closes by itself?
A garage door that opens by itself is usually caused by a stuck or shorted wall button, a remote button being pressed in a bag or car, radio interference, or a failing opener logic board.
Garage door is crooked or uneven?
A crooked or uneven garage door usually means a lift cable has slipped off or broken on one side, a roller has left the track, or one of two springs has failed.
Garage door shakes or jerks when opening?
A garage door that shakes or jerks while opening usually has worn or dry rollers, loose hardware, dry tracks, or a slightly bent track.
Garage door only opens partway then stops?
If your garage door opens only partway and stops, the usual causes are a broken spring (the opener cannot lift the full weight), an opener travel-limit set too low, an obstruction in the track, or hardened grease in cold weather.
Garage door wont open in cold weather?
When a garage door will not open in the cold, the bottom seal is usually frozen to the concrete, the grease in the tracks has hardened, or the opener's force setting is too sensitive for the added resistance.
Garage door sensor light is blinking?
A blinking sensor light (and a door that will not close) almost always means the two photo-eye sensors near the floor are misaligned, dirty, or have a loose wire, so they cannot 'see' each other.
Garage door opener is beeping or chirping?
A garage door opener that beeps or chirps usually has a low or failing backup battery (required on many newer openers), or it is signaling a programming mode or a timer-to-close warning before the door moves.
Garage door is hard to lift by hand?
A properly balanced garage door should lift easily by hand and stay open about waist-to-shoulder height.
Garage door panel is cracked or dented?
A cracked or dented garage door panel can often be replaced as a single section rather than replacing the whole door, saving you money, as long as the door model is still available and the rest of the door is sound.
Garage door has a gap at the bottom when closed?
A gap under a closed garage door is usually a worn or shrunken bottom weather seal, an uneven or sloped floor, or an opener down-travel limit set too high.
Garage door myQ wont connect to Wi-Fi?
myQ (LiftMaster and Chamberlain) usually fails to connect because it needs a 2.
Garage door clicks but wont open?
If the opener clicks but the door does not open, the motor is getting a signal but cannot run, commonly a failed starting capacitor or logic board, or the motor is being asked to lift a door held down by a broken spring.
