Chamberlain Garage Door Opener

[jayste]

Thanks for the information, Jay. I've not opened this door opener up or looked inside, and really have no idea how old it is. We bought this house 4 years ago this month, it was built in 1991, and apparently had extensive remodeling done in 1999.

No problem Bird. Yes, if I was to guess it's probably belt driven. "If it ain't broke don't fix it", right?

I have a Chamberlain 1/2 hp too, but with chain drive. Not long ago, SOMEBODY was careless throwing a tool into the corner and destroyed the electric eye. I ordered it from them, and was really pleased with the prompt shipping, clear instructions on how to install and adjust. Also had to replace a motherboard on warranty 2 yrs. ago, and they were good with service on that, too.

Rob, I know what you mean. That corner in the garage is a handy place to store tools but can be hard on the sensors at times. Normally they get bumped out of adjustment but sounds like your deal was a little worse!

Good thing your mother board was under warranty. Sometimes it's a tough decision to just buy another operator or replace the board.

I've had the Wayne Dalton openers (integrated spring and opener), which look pretty and save overhead space but have been a never ending pain to keep working correctly. For parts I've used Pro Door Parts: Wayne Dalton Garage Door Parts, Openers, Springs, Keyless Remote Controllers and have been happy with pricing and service. I was glad to replace the Wayne Dalton with the Liftmaster 3800 Jackshaft opener and added one to my 12' shop doors and have been very happy. Easy to install, work well, very quiet. One of the logic boards went out and I called Liftmaster, sent me another right out.

FYI, again, you fellas that are having the gear issues on your openers should seriously consider checking your spring tension. A heavy door will really shorten the life of the gear if the operator is adjusted too high on the force setting.

Jay, I checked my garage door yesterday. I disconnected from the rack and lifted the door by hand up to about waist high. When I let go, my door didn't budge. The door seems so well balanced that it sits there like it was in an indent. It has no inclination to go up or down. I also bought some lithium grease for the jackscrew, so I'll start lubing it about once per month as needed. Thanks for your help and suggestions.

Jim,

Great! Sounds very balanced. Won't be any spring adjusting around there for a while! Glad the info could help.

I have 2 large torsion springs above the 20' door. Correct settings is 1 round on the spring for every ft. height of the door. 9-10' high door = 9 to 10 rounds on each spring

Yes, that would be a good starting point. That's what would be applied to a totally unloaded tension door. If it's already loaded then try adding a turn per spring to adjust for fall.
