This is a Stanley garage door opener chain drive style, 0.5 horsepower. Model UT300 made in 1994.
The problem is when I try to open it, either from the remote or wall unit, it travels open for 1-2 feet and stops, and start ticking (with Di-Da-Di-Da sound in one second interval). This is the same with or without the door engaged.
I have tried the opener without the door engaged or the chain engaged. in both cases got the same results, so the problem is neither the door or the chain or the rail...
I guess the opener is actually fine but there are some procedures to follow when setting up. I don't have the instrution manual as the opener is from previous owner of the house. Could someone kindly point me to the right setup proceudre or maybe email me the right step or the related page?
