[Histonet] need help with Shandon Embedding center repair

[HCS]

Hi.  I am repairing my Shandon embedding center 11.   It is overheating and will not respond to setting the temp adjustment.  With a similar problem, I replaced a component many years ago and need to do this again, but have no manual or instructions.  Would someone have a service manual (or just a copy of the appropriate pages to guide me through this.   I am also wondering about the exact part number for the module that is to be replaced.  ( I believe it is BC332X14A).
Any help would be greatly appreciated.
