When install the door goes down to close but comes back up

check your sensors on the door frame,make sure they arent blocked or dirty or bent

Greetings,
There is something blocking the door from closing. Look around to make sure there is nothing near it or touching it.
Once I had a rolledup screen that started to interfere with the closing. Keep all things clear from it.

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.

If the main light flashes 10 times when the door goes back up it is a door sensor problem. You chain should sag just a little. If you tighten it too much it will click as it goes over the sprocket. You can increase the down force which is an adjustment near where all those white wires go. A 1/4 turn should be enough. Release the door from the opener and operate it by hand. It should move freely and when you have the door approximately waist high it should stay put. Neither raising nor closing.

What is wrong is you need to adjust the limit on the door when it comes up. What it is doing is coming to far back on the track. You need to push the back limit forward away from the motor so the door does not come back and drop down on the inside of the garage. The opener is trying to push the door up hill to get it to close that is why you are getting the bend in the track.


Good Luck

You need a general inspection of all related parts. Make sure none of the track mounting bolts have loosened leaving a misalignment of track segments. CAREFULLY with power off use fingers. turn EACH roller. Something as simple as a bad roller bearing can cause this, even a flat spot on a worn roller. Rollers can be bought at a home supply store. These are 2 most causes.

What is the model number of your opener. It matters.

Check your down limit switch and even your up one too almost sounds like one is stuck one way or the other.

You have a problem with the safety eyes. Make sure both eyes have a lit Led light, if not realign sensors
