TouchNGo opener failure to open

1. Step one - when it's hot and acting up, close the door, disconnect the opener, and open it manually. If thermal expansion is making the door bind, you need to address the basic mechanical issues of the door mechanism BEFORE you start cranking up the door opener. Clean, lubricate, adjust, or call a garage door mechanic, as apprpriate to the issues and your skills.
2. Then go though the complete adjustment procedure for your opener, including the safety tests that are supposed to be run every 6 months or so (stops when beam broken, stops and reverses when hitting a 2x4 laid flat on the floor, closes and stops correctly when nothing is in the way, opens correctly. At this point you may adjust the force if the mechanics are correct.
3. If you've done those things and it still acts up when hot, or if your adjustment procedure doesn't seem to work as it should if you do it when it's hot, you may have a problem (evidently of a thermal nature, or aggravated by heat) in the logic board of the opener. I had some very puzzling behavior from an opener once that appeared to have been caused by a nearby lighting strike scrambling it's little brains, and making it into a potential killer (it was trying to drive the garage door through the floor when it closed.)

Try disconnecting the door from the opener. Then you can open and close the door by hand to see if there is anything stuck or jammed. Could be that there is a kink in the track or one of the wheels is coming off the rail or something.

If door runs smoothly and without much effort then you can turn your attention to the opener. Note that it may be easier to just replace the whole unit; door openers are not that expensive. I certainly would not call a professional... a new opener is only $150 or so, you could easily blow through that with a diagnostic visit from a tech without actually getting to the real problem.

(If you have never disconnected the door before: there is usually a pull-cord or lever where the curved door arm meets the rail. Pull down to release the door, then push it back up to re-engage when you're done.)
