How old is this machine, and is this original board for this unit.I have been told by wiser ex york techs that the lithium battery has a limited life as also found in the manual.
The battery is only to hold the program during power failures. It has nothing to do with causing random faults or not starting. If the battery goes bad the chiller goes to the default program.

I changed several of these out on warranty/ customer sat work orders.
