Mine had that clicking noise. On mine (Craftsman chain drive) it was the safety sensors. I live near the coast (high humidity), as it turns out the safety sensors (electric eyes) develop corrosion and stop working, either that or the lenses get foggy???. If they don't "see" each other it stops the door from working. It happened many times. I finally got really pissed off and moved the eyes to a place where they wouldn't be exposed to so much moisture. I taped them directly to each other so that they would always "see" each other and put them in a low moisture location. The doors no longer have that "automatic trip" safety feature but they have not given me any trouble for over 15 years!! The door will still stop if it runs into something (internal clutch) but it can not see if anyone crosses under the door when it's closing. There's no way to remove the sensors from the system, they designed it that way.
Another thing I changed was the counterweight system. The high humidity would also rust the big spring in one year then it would break. It used to cost me $300 each year to replace the spring. That really pissed me off so I disconnected the spring and put in a counterweight system. I connected a cable from both sides of the door (8 X 10 door) to a pulley system to some steel (iron) weights. It's been working flawlessly for over 5 years now. No more damn springs to replace, I saved 1500 bucks, should have done it 20 years ago!!!
Now the garage door man is pissed!! He can't make any money off of me.:mad::mob::realcrazy::soapbox:
