This is a Stanley garage door opener chain drive style, 0.5 horsepower.
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 seconds interval). This is the same with or without the door engaged (so the door balance is not an issue here).
The load is probably not a issue either as the same problem is observed when I disengaged the drive chain.
Full close is not a problem.
I called the tech support at (former) Stanley and he told me the broken gears may be at fault. I opened the gears box and carefully examed the gears. They apprantly are in good condition.
Can someone shed a light on this myth? Or maybe the setup is not correct? I don't have the manual since it is inherit from the previous owner.
