I've been in the house for awhile and have gone through several different brands of garage door openers.

I presently have a Chamberlain with MYQ and battery backup purchased almost three years ago.

It is a belt drive and very quiet. It had operated flawlessly until a few days ago when I started having issues with sensor error messages and the door starting/stopping.

I replaced both sensors but, that led to the latest issue of excessive opening force and excessive closing force.

I realize that electronics and cheap Chicom parts are sometimes short lived.

Any recommendations on brands, etc...? Jackshaft versus conventional?

I really like the battery backup and open/close notification features.

Thanks!
