I recently changed the hinges on my garage door ( 1piece ) using Holmes e900 and new springs. My liftmaster 2220 is working really hard trying to pull the door up. The pull force is set to maximum and now it's making some grinding noise. I purchased it back in 2003. The door appears to be balanced and not binding anywhere. Any suggestions or advice on parts I might be able to change to bring new life to my Liftmaster ?
Thanks
