Liftmaster 1/2 HP

The outside push button control will close the door when the code is entered, but will not close the door. I replaced the 9v battery with no change. Everything else works ok. Any suggestions what to do next?

CORRECTION: The push button control will not open the door; however, it will close the door if it has been opened by the wall button or a remote.

It sounds like you have lost range with the keypad. The closed door may be adding enough resistance to shorten it even more. It will most probably involve a new keypad.

if your remotes have the same range as always , and another new battery doesnt help, clean battery contacts in keypad.

if still no go , replace.

YOu can test new remotes without opening package, unfortunately you cant test a keypad same way LOL
