You have a shiny new car and want to program your garage door opener to it. So you get out your garage door remote control and your new car's owner's manual for the instructions from the manufacturer to be able to program the remote control to the car. Then, after following the instructions from the manual, you press the button for the garage door to go up . . . and nothing happens. Did you miss a step? Read on to learn about what most instruction manuals leave out: the step of programming the car/truck/van to the garage door machine itself. The Logic BoardOn the back side of your garage door opener is a panel called the logic board (see the photo above). The logic board is the computer or brain of the machine. Most new garage door openers are multi-code machines. That means that they use several signals each time you press the button on your remote control. This is for security, so your code can't be stolen by a code-grabber. Programming a Vehicle to the Garage Door OpenerOnce you have followed the instructions on programing your machine, you now have to "teach" the garage door opener to connect to the remote device in your car.

First, press the "learn" button on the back of your garage door opener mounted on the ceiling. (The learn button, located on the back of your machine, will be square if using a Liftmaster machine. Craftsman, Liftmaster, Chamberlain are all the same. Their learn buttons are square and usually yellow, red/orange, or purple. If using a Genie, the button says "learn button.") The single press of this button should be brief and firm. Do not hold this button down. If you do, it erases all of the programming in the machine and you'll have to re-program all the remote controls that you have, and that's not a fun process. Quickly press the button on the remote control and hold it down a moment. If your car has a built-in button, then you'll need to have someone help you by pressing that button now. Programing the remote to the machine only takes a second. When the machine accepts the code, the light on the machine might flash for a brief moment, and you should hear an audible click.

Yep, it's that easy! I don't know why the auto makers leave this step out, but that's really it. I hope this helps, and if you have any questions, leave them in the comments below and I will try to walk you through it. Don't Hold the Learn Button DownIf you do, it erases all of the programming and you'll have to re-program all the remote controls you have.The garage door opener is equipped with two safety features that may prevent the door from closing and cause the lights to flash. The Lock Button on the Door Control The lock button on the door control may be activated. Press the button to turn this feature off. The light bulb will blink two times. This feature is designed to prompt you that the lock button is activated. When the lock button is ON the garage door opener will work from the door control but the remote controls are locked out. The most common reason for the lights to flash on the garage door opener and the door not closing is that the safety reversing sensors are misaligned or obstructed;

NOTE: The garage door can be closed by pressing and holding the door control push bar until down travel is completed.outdoor fire pit harbor freight I have a Craftsman 1/2 HP garage door opener. auto glass repair wellingtonIt's always been a little finicky, but tonight it stopped working. double glazed doors adjustmentIn the middle of going up as tonight, the door halted, leaving a gap between the door and the ground. I got out of the car, squeezed under the door and realized the motor was still running. My wife pushed the door opener a few more times, but the door wouldn't move despite the motor responding.

I pulled the release on the door and opened it all the way. I realized parking the car in the garage would be a hassle, since I would have the open the door manually again. So I just closed the garage with the chain disengaged. The motor will start and stop in response to button pushes like it is supposed to - normally the first push starts it in one direction, the 2nd reverses the direction and the 3rd will stop the motor. However, the chain has completely stopped moving (and by extension, so has the door). This causes the motor to run for an extensive period of time before it seems to timeout and give up. The chain and door connector assembly haven't budged since. I've not worked on garage doors before, but I have a degree in Computer/Electrical Engineering. I've never studied to be an electrician or anything, so I'm well aware there are a lot of things I don't know about this. But generally speaking, is this the type of thing I could potentially fix myself? Or is it more likely the whole unit is shot and I should just call a repairman up front?

I know I have the manual around here somewhere, I'll keep looking for it and list exact part numbers if I find it. Update: I popped the sprocket protector off just like in the video form Steven's answer and the chain is still firmly attached. When the motor is running, you can clearly see the shaft and sprocket are not moving at all, not even jerking when starting or stopping, like something had locked up the shaft. repair garage garage-door-opener garage-door It sounds like the chain might not be on the sprocket that drives it. Get up on a ladder and look at the top of the unit. You should be able to easily see if the chain is off the sprocket. Try running the opener while you are up there too. If the chain has come off you will need to loosen the chain tension, place the chain back over the sprocket and tighten it to the correct tension. Your user manual should have details on how to perform this but usually there is a screw you adjust on the trolley that controls the tension.

Make sure to disconnect your door from the trolley before you do this. Here's YouTube video that shows the process. I ended up having to have this replaced. I got a repairman out on a 'free housecall' who quoted me a price for the parts & labor. The price was less than a replacement, but the fellow warned me no one would warranty a repair on a 15 year old unit beyond 30 or 60 days. The unit originally had a 10 year warranty and was installed in 1999 (Craftsman garage door opener warranty page, for reference). It's possible that the fellow really needed to sell a unit and was underselling the feasibility of the repair. But I'll never know because I sprang for a replacement unit with a lifetime warranty through both the installation company and the manufacturer. Thank you for your interest in this question.
