Overhead Automatic Garage Door Troubleshooting

Automatic garage doors allow remote access into your garage.Automatic garage doors allow remote access into your garage.

Automatic overhead garage doors are common in homes across the nation and are preferred for those homeowners who have vehicles that they regularly park in the garage. This is opposed to manual doors, which are more common in garages that exist primarily as storage space. Since the overhead automatic door relies upon electrical components and various attachments to operate properly, there are numerous little things that can wear out over time. It is important to know how to troubleshoot your door to avoid costly repairs.

Door Stops When Closing

When the door begins its way down the tracks but stops before it reaches the bottom and actually closes, or if the door stops and then opens again, there may be something blocking the door's sensors. Automatic doors have sensors located along the track, usually somewhere around knee height. If something is blocking the signal/laser, the door won’t close. If there are no physical components blocking the signal, then the eye is potentially dirty and needs to be cleaned. If neither option helps, the sensor itself might be damaged and needs to be replaced by a technician.

Door Won't Open Via Controller

Although the most common instances of a door not opening from the controller stem from a low battery charge, there could also be issues with the breaker for the motor or a malfunction in the sensor. Change the batteries first and see if that works. If not, physically enter the garage and hit the switch that opens the door from the inside. If your door opens with the switch, then you have an issue with the sensor in your controller, or the sensor on the motor that reads your controller. Check the lenses of both to ensure they are cleaned for optimal use.
