My door only opens about a foot and slams back down. I heard a loud bang and now my door won’t open.

You probably have a broken spring.  Call R&S Doors & Gates for this type of service, as it can be very dangerous without the right tools and expertise.

​

All of my remotes quit working.

Check the lock button on your wall button. This feature turns off the radio frequency for your motor, therefore all of your remotes will not work while it is on. Press and hold the lock button for 3 seconds to turn it off in most cases.

​

The motor runs, but the door won’t move.

Make sure the operator didn’t become disengaged. If you can lift your door by hand without pulling on the red release cord then it is disengaged. Re-engage the door by pulling the red release cord, put the door halfway open, and hit the wall button. It should automatically engage itself. If it doesn’t, see your owner's manual for more details.

​

If it is not disengaged then you probably have a stripped gear or carriage depending on the type of motor you have. Call R&S Doors & Gates for this type of service to ensure it is properly repaired.

​

The door makes a screeching sound when it opens and closes.

It might be time for a service, lube, and adjust if you haven’t had one in a while. Try lubing the moving parts of the door with a silicone spray. If you have old steel ball bearing rollers, it might be time to replace them with new nylon coated bearing rollers to quiet the door down.

​

There is a gap under my door.

Depending on the type of door, it might need a limit adjustment or even new astragal. Check your concrete. It may be uneven, causing gaps along the bottom.

​

The door starts to go down then reverses and goes back up and the lights start blinking.
