Why does my garage door Open with remote but not close with it?
There is a problem with safety sensors. They are probably missing align. They are usually mounted at the bottom of your garage door tracks. Make sure nothing is in the way and they point directly at each other.
Each safety sensor has a small light. When they are correctly aligned both lights will be on. Safety sensors are shown here at the bottom of the picture.
The garage door opener limit switch tells the motor that lifts and lowers the garage door when to stop running. Incorrectly set limit switches may prevent your garage door from closing completely or opening all the way.
They can also cause the opener to reverse or pull back up when you attempt to close it, which can seem like a malfunction or that someone else is using a garage door opener remote that is on the same frequency as yours. This is actually caused by a safety mechanism meant to protect people from being hit and having the door close on them.
