Hi,

I have just bought a Challenger CH 1000 garage door opener which has come without any fitting instructions Has anyone got some instructions or can tell me how the chain drive joins the garage door.

JESSICA5 - hi, did you buy the unit used from someone? If so, it appears they didn't give you the bracket that mounts to the door. That bracket connects to the end of the chain drive and is what pulls the door open/pushes it closed. If you didn't get a bracket, you may find a suitable one at your local big-box stores. You should be able to find installation instructions on the web as well. Good luck! Jim D/West Point, VA

I have two of these CH 1000 Door openers working in my garage.
The chain runs to an idler sprocket
attached to the wall above the door.
One of those push-pull rods attaches
one end to the door about a foot below the top & the other end of the rod attaches to a slider that the chain pulls back and forth. There are stops on the chain that hit the stops on the drive unit which reverses the direction of the chain next time it's actuated.
If you'll send me an email at
fwoodruf@charter.net
I'll send you a picture or two of it.
Where in the world did you purchase the door drive assembly? I need one of the circuit cards that mount inside the drive unit, but I'd be glad to purchase the whole assembly just to get the card - - - unless it costs a zillion bucks.
