The NUMBER on the older SE control boards = 40283 or FL40283, and some SXT version might have BR42195 or 42196 showing on the Board,BUT that is not the Part Number of the Control... it's only the Circuit Board Number.All new SXT have Circuit Board Number of 42196, but again, there are Different VERSIONS
.Note there are several different "face" plates used depending on the Valve Model.
