Need Advice

I have 2 15 year old Chamberlain Liftmaster Professional Units with wood doors.

One unit, as far as I can tell, just failed. It goes an inch then makes a grinding noise. Externally, the chains and such look fine.

What should I do? Replace that one unit, or both, or get a repair estimate? Also, one just replaces the mechanized unit, not the chains/rail, or the whole thing. Also, I'm not handy, so I'll be having someone do it for me. Handyman or professional, and how much time will it take them?

Thanks for any help/advice, much appreciated!
