My garage door opens fine, just wont close with remotes. Lights just flash. I have to use the opener in garage and keep the button pressed in till the door is fully closed or it will reverse.

The motor/control unit may have gotten reset. It needs to relearn the codes transmitted by the remotes.

MIne has a "learn" button on the control unit. Press and hold, then press the button on the remote. Lights will flash indicating it has received and stored the code. Release button.

Check to see if the remote works now. If so, all three should be working. If not, dig up your manuals.

If the main light flashes 10 times when the door reverses to the open position it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have bad sensors.

Make sure the sensors are still pointed at one another. If you tweak them and cannot get the light to come on the sensor is bad and must be replaced.

On the wall control with the flashing light press and hold the button with the lock icon for 3 seconds and release.

It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

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.

Most openers are programmed the same. You normally program the house garage opener to accept the new remote. Your garage opener will have a button to press to add in a new remote. Normally you press this and then press the remote in the car and hold until your lights on your opener flash or the garage door closes. (check your manual on your garage door opener)

Align sensors or replace,

Press and hold the homelink button and wait till the red light flashes slowly,but don't release it. Now hold a working remote 3 inches away,press the remote button and hold it.When the red Homelink buttom fllashes quickly, release both buttons. Now go to the opener and push the learn button. Now go back to your car and press and hold the Homelink button. You will see the lights on your opener flash. Now your Homelink button should operate your garage door.

How do you change the code?
