Looking looking up the page in your owner's manual shows the part's list and it lists this part as working in your garage door opener

I have a chamberlain liftmaster part number 41a5483b from 2003. will this part work?

Me too! And yes, it works great. The part number you reference appears to be the logic board on the back of the unit. On the front, chain side, is the name plate with the model number. Mine is model 2265R and if yours is also a 2265-ish, this replacement works great.
