Replace garage door opener head unit & use the same rail?

8 years ago

hi can I replace a 2005 Chamberlain Power Drive head unit with a new Liftmaster 8550w and use the same rail? Also, is there a list of parts (or better yet a kit) that includes the belt, etc that I will need?

I'm a little confused as what you're trying to accomplish. Since Chamberlain makes Liftmaster the odds are pretty good the rails will be the same but given that the rail is pretty easy to put together and install, why bother. The rails will come with a new unit (unless you're trying to piecemeal things).

If the motor on your old opener runs but the trolley doesn't move there's a good shot that a couple of nylon gears inside are shot. It's a common problem with Chamberlain/Liftmaster openers. A repair kit is available for about $30 online or from a garage door shop.

Thanks for responding – I just want to upgrade my head unit to get battery back up capability and built-in myQ goodness

The unit I was looking at on Amazon did not come with the rail but I think I just need to look for a replacement that includes the rail - thanks again
