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!

I guess my question was whether the stats, e.g. number of teeth per inch, width, thickness on garage door belts are standardized/universal. It's good information that you were able to reuse the chain and replacing it isn't that hard to do, thanks!

Liftmaster and Chamberlain are the same company, so it's highly likely (though not guaranteed) that the parts are compatible.

I was thinking there would be a chance of that. In researching the replacement circuit board they seem big into backwards compatibility.
