There are screws on the unit to adjust the opening and closing tension and place it stops. They are probably set for the previous installation and need to be adjusted for yours.

Check that the wheels and bearings are turning freely and that the door is not cocking to one side when closing. If the wheels are catching because of bad bearings, because the tracks are out of true or because the door is not staying straight in the tracks, the motor thinks that the door is hitting a car or a person and reverses. One thing to try: disengage the motor and try moving the door through the full traverse. Most automatic doors have a pull-cord that disengages the door from the motor. CAUTION: You may need a friend to help with the door, because it could be surprisingly heavy,.

It could be as simple as a drive motor force adjustment...
(you will have to get out the instruction manual)

Most likely your balance spring... one has failed

look over your springs very carefully... if one has shattered your counter-weigh is only lifting HALF the weight of your door.

Most garage doors need to be fairly NEUTRALLY BALANCED for the best, longest and reliable use.

Routine lubrication of the springs can add decades of useful life to your springs... CHATTERING Springs make a lot of noise and will soon shatter (break).

Sears makes house calls...
but they try to sell openers... you don't need.

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.

U need to check the safety sensors. There may be a blockage in front of them... or one or both sensors have gone bad. Make sure the wiring from the sensors is complete to the opener unit first. There should be led lights on the sensors to indicate if they are functioning. One thing you should do is read your owners manual. If you can not locate it check online for a copy or reach out to the manufacturer since this is a safety issue they should be willing to help you. When it comes to solving issues we tend not to take the time to read things first. I even do it myself. I have had this problem and had to press the open/close switch until the door was fully closed. Most types of safety sensors are available online or in the big home repair retailers. Good luck

if you are using the new florescent bulbs they don't always seat deep enough. Unplug the opener remove the bulb in the bottom of the socket there's a metal tab use your finger or a small screwdriver and bend/lift the tab up a little bit. this should fix your problem
