How do I prevent or troubleshoot my garage door opener from stalling and not completely closing?

Question

I have 1/2 HP screw drive garage door opener. I like this model because it has a SAFE-T beam feature that stops the door if a child is under the door while the opener is closing down.

Now, the problem is that when I use the control by the wall, I can close it but when I use the remote control, I had to press it so many times before the door closes, if at all. 95% of the time, the door just starts to close and then springs back up, even if there is no object obstructing the laser beam at the bottom. I have cleaned the glass of the "eye", replaced the battery for the control with a new, fresh one, replaced the coil springs and still no luck. I am resigned to getting out of my truck each time and use the wall control and lower the door to a point where I can I can slip right thru and use the remote to close the door completely. In short, I have to use both the wall control and remote control to open and close my garage door.

Any suggestions? Help!

Good Luck

You need to adjust the sensor that makes it open if the door contacts something before it is fully closed. Refer to the owners manual

I had this problem with my door opener. Make sure the sensors are aligned. You'd be surprised how easily they get out of alignment.
