You may not have had the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear. Loosen the coupler up and from the front of the motor (opposite end in which the coupler is on) push the shaft back as far as it will go.

The most likely problem here is that your wall control is bad. I would disconnect the 2 wires going to it and I think you will find your remote works. Replace the wall control.
Garage door open and closes by itself
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’s purse that gets the button pushed by other stuff in the purse.
The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

GEAR END AT DOOR DOES IT HAVE TO BE MOUNTED TO HEADER WALL?
It can be mounted to a ceiling rafter, but make sure there is room above to allow for the trolley to travel freely. If there is a clearance issue, there are top roller adapters called "quick turn brackets that make the top of the door turn faster and lower. Most likely available from your local garage door company.
