Wont go down

The door will operate from the inside only if I hold the button down continously till it reaches the bottom. If you use the remote from the car it will not function at all. It seems like to me that the sensors are malfunctioning some how. If I let go of the button and the door is not all the way to the bottom it retracts and goes back up.

I had the same problem with my daughter's garage door. The problem indeed was the sensors at the bottom of the door which protects kids, pets, etc. First, make sure the wires are connected to the properly color-coded screws on the unit. I believe one is white and the other has a black stripe. Of course the sensors have to be aligned. If properly connected and aligned there should be a green LED on BOTH sensor units.

Door goes down and when it stops at botton, it turns and goes back up ??? Need adjusting ..How can I adjust???


Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close)
Setting the up position: 1. Press and hold the black button until the LED starts flashing slowly, then release. 2. Push and hold the black button until the door reaches the desired UP (open) position 3. Push the door control or programmed remote control. This sets the Up (open) position and begins closing the door. 4. Immediately when the door begins to close press and release the black or purple button. This will stop the door Setting the Down position: 5. Push and hold the purple button until the door reaches the desired DOWN (Closed) position. 6. Once the door is closed, If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position. 7. Push the door control or programmed remote control. This sets the Down (closed) limit and the door should open.

The back door won't unlock or open and the front doors won't unlock by the remote


Simple enough to reset the power locking system:
1) make sure battery in remote is good, if in doubt replace it. Next unlock all the doors and keep them closed.
2) Jack up the car and you'll find the power lock reset button above the fuel tank. If you cant reach it drop the tank down slightly until you are able.
3) Depress the power lock reset button, then get inside the car and hold the unlock button on the remote for 2 min.
4) The system will reset when you get out of the car and hold the lock button for another 2 min while circling the car briskly.

Remote does not open or close garage door; inside button flashes


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.
