If you wonder why your garage door closes and then opens without completing an entire cycle, read on. Garage doors have many moving parts; even a single malfunction can affect the whole operation. So today, the team at Raynor Garage Doors is here with this quick guide on troubleshooting if your garage door keeps opening and closing automatically.
Checklist for When Your Garage Door Closes Then Opens
If you notice your garage door closes and then opens prematurely, go down the following checklist to identify the problem.
Garage Opener Buttons
The first thing to check is your garage door opener button. The buttons on old or dirty opener remote controls can become stuck and constantly send an open/close signal to your garage door. If possible, you can switch out the buttons to see if that fixes the problem. Consider buying a new garage door opener remote if that doesn’t work.
The Sensor is Unaligned
Modern garage doors have an infrared sensor near the bottom that stops the door from closing if something is in the way. If sensors are unaligned, they might detect an obstruction when nothing is actually there, so the door opens and closes erratically without a discernible cause.
Limit Settings
Garage doors have a limit setting that limits how much force they can exert before they automatically shut down. A garage door opening and closing erratically could be because the limit setting is too low. You can adjust the motor unit’s limit setting and door reverse so it won’t automatically shut down.
Control Wiring
Garage doors have control wiring that runs between the wall control and the motor unit. If these wires are frayed or have damage, it can cause electrical surges causing your garage door to open automatically. If you notice broken wires, you should call an expert for garage door service. Working with electrical circuits can be dangerous if you don’t know what you are doing.
Electrical Circuits
In some cases, erratic garage door behaviour could be a result of electrical faults in the main circuit board. Circuit boards can sustain damage from electrical surges, bad weather, and power outages. Circuit board problems are a safety and security risk as they can cause your door to open and close unexpectedly. If you suspect electrical problems, you should call an expert garage door technician.
Force Settings
Another reason why your garage door closes and then opens could be the force settings. Your garage door force settings might be too low, so the door thinks it’s done opening when it’s actually not. You can increase the amount of force through the motor unit.
