Ive got an old sears 1/2 hp opener.
The gears were stripped so I replaced them.
The darn thing will only go up about 8 inches then it goes back down. It does this when the chain is on or off the sprocket.
I can’t adjust it and I don’t have a manual for it.
I gave Sears a call with a few questions but they are worthless.
Has anyone had this problem?
Are there any garage door opener service guys at IDO in the Inver Grove Heights area?
Thanks
