Question about Building Materials
My liftmaster formula1 opens everytime but only the wall button will close it. Once in a while a remote will work but rarely. I have one remote, one vehicle oem remote and a wall mounted remote outside. All 3 are sporadic when closing, all 3 will open the door no problem. Only the wall mount inside the garage will close the door everytime.
Does it attempt to close. stop go back up and the lights flash....if so check the safety eyes, check for boken spring/ springs using the wall mount button circumvents the safety system. check the down pressure setting.

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

Hold the button with the lock icon in for 3 seconds. This should toggle the unit off vacation mode and your remotes will work.

COULD BE A BAD REMOTE, I WOULD TRY ANOTHER ONE FIRST.
COULD BE A FREEZER ETC. PUTTING OUT INTERFERENCE.
Anytime a door opens and/or closes randomly or doesn't work consistently I look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone
