Remove the Old Opener

On the back side of the motor unit, take a photo with your smartphone or label the wiring that runs from the ceiling and connects to the machine. You’ll be assembling those wires the same way in the new garage opener replacement.

Unscrew the screws holding the wiring in place and simply pull the wires out.

Next, you’re going to be unfastening and removing the entire garage door opener unit – but first, you’ll want to put a folding table or other supporting surface below, to place the motor unit on after you lower it down.

Detach the chain from the sprocket and let it slide down the rail. Then, using a socket wrench, unbolt the bolts along the bracket holding the opener in place.

Lower the opener slowly down onto the table. Using a socket wrench, unbolt the unit from the railing.


Install the New Opener

Raise the motor unit upward, climb up on the ladder, and, supporting it with one hand, use your other hand to slide the bolts through the bracket and into the garage door opener. Then, tighten them up.

When it comes time to reattach the chain, if the chain is too tight you can go to the front of the rail, loosen the nuts on the trolley, and adjust the chain tension so that you have enough slack to loop the chain onto the sprocket. Once it’s on there, you can tighten up your chain tension again so the chain doesn’t flap loose.


Make any necessary adjustments

Try opening and closing your garage door. If it bounces back up again, odds are that the door is hanging too low or that the down limit is too high.

Open the garage door, leaving it open, and see if the garage door hangs down a bit. If it does, adjust the up limit on the side of your garage door motor unit, turning rightward to increase, and then see if the garage door opens all the way. If the garage door doesn’t hang down, try decreasing the down limit slightly by turning it to the left.

Make sure to test the safety sensors by tripping them as you close the garage door, seeing if it goes back up. If not, try making sure the wires are secured, or follow our sensor troubleshooting steps.
