Garage door opener replacement questions (lemmy.world)

I think some electronics in the motor have gone kaput. The wall mounted button works, but I have 2 remotes and neither works. (I did change the battery on one as well as try to re-pair it with the motor, to no avail.)

My options are to replace the circuit board ($125) or buy a new motor unit ($199). The original motor is a Liftmaster and the lift is a belt; it's probably about 20 years old. The cost of a new motor unit is not hugely more than the circuit board and I would get additional features like a battery backup.

If I go for a new unit will it work with the existing belt? I'm looking at a basic 1/2hp Chamberlain. Thanks!

Thanks. Not going near the springs. I've seen many posts where people want to replace them themselves and everyone advises against it. I've worked on the motor unit before - the gears (nylon I think) had gotten chewed up somehow and I replaced them.
