Toshiba e studio 6525 robort the machine C4b1 anybody get this problem

[Rusty.Harris]

Any chance someone installed a fuser unit that is not for a 6525AC? Or, did someone swap out an IH board that wasn't for a 6525AC?
Although many of the 2525/3525/4525 machines look similar, many of the parts DO NOT swap between machines.
