Check to make sure that the garage door is balanced. Sounds like the springs need to be adjusted and the travel limits need to be reset.

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.

You need to check the door springs to see if one is broken and also remove the cover from the motor unit and check the drive gear. The gear is white nylon and will be very obvious if it is bad. The part number is 41A2817 and is available at any good door service company. It will come with instructions.

Door sensors have nothing to do with door opening. Only closing. It sounds like you have a bad gear in the motor unit. Remove the cover and it will be obvious if the gear is bad.

The laser eyes have to go on in a certain way. One of the eyes can not be where it will get direct sunlight.

Most likely your door sensors are out of alignment. Make sure they are pointed directly at one another.

Sears opener wont open or close more than 12 inches


You may have put the chain back on out of "sync" with in internal up and down stops. You may have to take the chain off the motor sprocket and run the motor to make sure it is stopped in the down position ( watch the rotation of the sprocket to determine up or down position) When the motor is stopped in the down position put the chain back on with the chain Carriage in the down position. Then you can fine tune the up and down stop positions with the adjustment screws on the side.
