Twenty year old ***** [139.664983] ½ HP Garage door opener. Unit operates flawlessly during cool weather, but reverses itself (while traveling in either direction) when temperature hits 80 degrees or so. Rollers have been replaced and door is not binding and moves freely when opener is disconnected. Automatic reversal doesn't occur all the time, but does happen often enough (maybe 6 out of 10 openings/closings will require 3 or 4 attempts to complete) to be a nuisance. Obviously after 20 years I've gotten my money's worth from the opener and the "problem' is easily solved with a $200 check; however, it has become a challenge! I've removed the cover to help with the cooling plus I've "cleaned" the cards and electrical components with compressed air. Any suggestions on what is getting too hot and how to correct?

Dear Bill,
I had this problem a few years ago and it was the proximity switch that was out of adjustment. That's the switch that won't let one get clobbered while standing under the closing door.It's either being bumped during operation or simply kaput.
