When your garage door won’t open or close, it can be a frustrating and inconvenient problem. Fortunately, the cause is often simple, and the solution can be low-cost and easy—sometimes without the need to call a professional. Here are 15 common garage door issues and their solutions to help you troubleshoot and fix the problem.
1. Misaligned Photo Eye Sensors
If your garage door won’t close, the safety sensors might need realignment. Located near the bottom of the door track on both sides, these electronic eyes require a clear line of sight between them. If the line of sight is clear, the door will close smoothly. However, if the brackets holding the sensors are misaligned, the door will stop or reverse, and lights may flash to indicate a problem. Adjust the sensors or brackets by hand to ensure a clear line of sight.
2. Dirty Photo Eye Sensors
Debris or dirt on the photo eye sensors can also prevent the garage door from closing. Ensure there are no obstructions in the sensors’ sight path. Gently wipe the “eye” portion of each sensor, taking care not to misalign them.
3. Malfunctioning Remote or Keypad
If your garage door won’t open, it could be due to a faulty remote control or keypad. If the door opens with the hardwired wall switch, the problem is likely with the remote or keypad battery. Replace the battery and check that the antenna on the motor unit is hanging downwards and is undamaged. If the issue persists, reprogram the remote or keypad according to the manufacturer’s instructions.
4. Rollers Need Lubrication
During cold months, garage door rollers can stiffen, causing the door to open slowly or not at all. Lubricate the rollers with white lithium or silicone lubricant, which won’t attract dirt or cake up. If the door still doesn’t open, adjust the sensitivity of the opener by following the owner’s manual instructions.
5. Damaged Rollers
Rusted or damaged rollers can cause the door to bind in the tracks, preventing it from opening. Replacing or lubricating the rollers with silicone or white lithium lubricant can solve this problem. Regular maintenance ensures smooth operation.
6. Unplugged Garage Door Opener Motor
Check the power source if the garage door doesn’t open when the remote or wall switch is pressed. Often, the motor unit has been unplugged. Ensure the cord is securely plugged into the ceiling outlet.
7. Power Disruption to Motor
If the motor is plugged in, a tripped circuit breaker, blown fuse, or GFCI outlet might be the culprit. If other electrical circuits or lights in the garage aren’t functioning, reset the breaker or GFCI or replace the fuse. Repeated tripping indicates a short circuit, possibly within the opener itself.
8. Up-Limit Switch Needs Adjustment
When the garage door opens partially, the up-limit switch may need to be moved closer to the motor unit. This touch-lever switch is usually mounted on the track near the motor. If it’s too far away, the motor will stop the door before it fully opens. Adjusting the switch’s position should resolve the issue.
9. Up-Limit Switch Needs Repositioning
If the garage door opens but the motor keeps running, the up-limit switch might need to be moved away from the motor unit. This problem is common after a new opener installation or if the motor’s gears are stripped. Adjust the switch to stop the motor from running continuously.
10. Close-Limit Switch Needs Adjustment
A misadjusted close-limit switch can prevent the garage door from closing completely or cause it to reverse. This switch ensures the door doesn’t close on people or objects. Adjust the switch to correct the door’s behavior.
11. Close-Force Screw Needs Adjustment
If the garage door reverses before touching the floor, adjust the close-force screw. This screw controls the pressure required to close the door. Reduce the sensitivity so the door descends fully without reversing prematurely.
12. Faulty Garage Door Opener Motor
A garage door that won’t open might have a burnt-out motor. Replace the motor yourself or call a technician for assistance.
13. Worn Springs
Torsion or extension springs that assist in lifting the garage door can wear out over time. Torsion springs, located above the door, are dangerous to replace and should be handled by a technician. Extension springs, on the sides, can be replaced by homeowners with appropriate care.
14. Snapped Garage Door Cable
The door springs work with cables to lift the door safely. A snapped or misaligned cable can cause the door to malfunction. It’s best to have a professional replace the cable to avoid injury.
15. Off-Track Garage Door
A door that’s off track due to loose tracks can be realigned by loosening the track screws, tapping the track back into place with a block of wood or rubber mallet, and then retightening the screws.
