hello,
I have been having some problems with my garage door opener carriage disengaging by itself
. I engage it and after a couple of uses (3-5) the screw rotates but the door does not move, the carriage disengages itself. I checked the screw for any inperfections that would disengage the carriage but i see nothing. I'm afraid that if i replace the carriage the same thing will continue happening. I have been looking all over the internet for an answer but can't find any info. please help.
