just recently my door stopped going down completely. i tried everything the manual said to do...the sensor lights are on full-time. i adjusted force and distance. today i released the door from the chain...then i tried to open and close it...opened fine, as it did with door connected. stopped going down just as it does with the door connected.

should i try more adjustments? if so, which ones.

btw...it does this with all remotes.
