This problem is most commonly caused by a bad wall control or the wiring to it. The staples holding the wires can cut through the insulation and cause intermittent shorting. The wall control goes bad from constant use.

I have liftmasterPro garage door opener. How do i


You cannot change the code of the opener without purchasing new remotes and not using your existing remotes. To change the code of the keypad locate the smart/learn button just to the left of all those white wires. Press and immediately release this and then walk over and key in any 4 digit number and press enter.

I have 2 liftmaster 3245. The hand held remotes were working fine then stopped. I replaced the batteries and turned of all electrical/RIF close by. Still not working. Both cars operate the doors with no...


You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

I have a liftmaster garage door i dont know the current code how do i reset the keypad?


LIFTMASTER OPENERS HAVE A SQUARE BUTTON ON THE BACK PANEL. PUSH THE BUTTON ONCE AND PUNCH IN THE CODE YOU WANT ON THE KEYPAD - YOU ONLY HAVE 20 SECONDS - THE NEXT TIME YOU PRESS ENTER IT SHOULD OPEN/CLOSE THE DOOR

Garage door opening by itself


Anytime a door opens and/or closes by itself 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.

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 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.
