garage door stops after lube and tightening
One weekend project was to lubricate my garage door (Chamberlain opener; Clopay door). It was a lot quieter when new (~2 yeears old), so figured I could quiet it back down. Put some silicone lube on the hinges and tightened the lag screws on the hinges. Went up and down just fine several times. Came out later that night to open it, and it would go up only 6 inches. Not an issue of security eye, since no blinking lights. Released opener and pushed it up with no problem. Reconnected. Same issue. Put some more lube on. Same issue. Loosened the lag screws a bit where I'd tightened them. That seemed to do the trick.
What's going on here? Should the lag screws be slightly loose (1/2 turn about)? Does that allow just enough play for an imperfectly straight track?
