Garage door goes down a foot and goes back up. light by learn button flashes five times

It's on the back of the motor. Press the learn then the remote button. You should hear it click and the light bulb should flash.

Try turning your down force up alittle higher if your door is only wanting to go down a foot or so. If your light bulbs are flashing, you then have a problem with the safety eyes.

3 FLASHES

Depends which kind of garage opener you have. But generally, it goes like this:

In car, press and hold 2 outer buttons on overhead console until indicator lights start flashing.

Hold desired button you want to program garage opener with until lights begin to flash rapidly.

At the garage door receiver in the garage, press the "learn" button. (Mine was located under one of the plastic light covers; it is purple in mine, can be other colors, but should say "learn button" or something similar) If I recall correctly, the light next to the learn button started flashing after I pressed it.

Quickly go back to the car, and press and hold the desired button and the garage should close.

That should be it.

Here is the information I have for homelink.

1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxilary, and/or the car door must be shut).
   

2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.
   

3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light. Press this learn button momentarily. The indicator light will turn on and blink if Genie or otherwise stay lit. For Genie systems, go back to the in-car transmitter button you programmed and press this button 3 or 4 times, or until the door starts moving. This should set your in-car transmitter to your garage door opener. For Liftmaster, Sears, or Linear Megacode press and hold the in-car button you programmed until the garage opener light flashes. Your in-car is now programmed to operate your door.

If this doesn't work your car and homelink may not be compatible.

If the main light flashes 10 times when the door reverses you have a door sensor problem. Make sure one of them hasn't been bumped and that they are pointed at one another. Each one has a small light that should be lit and not flickering. Both lights will only be on if they are properly aligned. If the main light is not flashing then you probably have a problem with the RPM sensor which is a small printed circuit board just in front of the motor. Usually when this is bad the small LED near all those white wires will be flashing 5 times then pausing and repeating.

If when it does this your main light flashes 10 times it is the door sensors. Make sure they are aligned properly. If the main light doesn't flash 10 times then you most likely have a bad RPM sensor board. It is a small printed circuit board just in front of the motor.

What has happened is that you electric eyes are blocked or have gone out. The eyes are at the garage door about a foot of the ground on both sides. There should be a red or green light on one of them. If not some thing is blocking the beam that goes across the door. It is a safety beam so kids can nt get hurt when the door is coming down. If the beam is broke the door will go back up.
