C3425 then C3B02 on C652 photocopier

[Geoff Taylor]

C3425 Fault , IH Power supply fuse blown.(IHPU)
Replaced IH Power supply, Relay Drive board (REDB) and Printer Control PWB(PRCB)
Did trouble Reset, Has new Fuser Assy
Temperature readings were as such:
middle temp 53
heat protector 78
heat edge 52
soaking side 110
machine sensor temperature 85
Took heated fuser from another machine
machine was ok for approximately 2 minutes then the power tripped and blew the IHPU fuse and came up with a C3B02 fault.
I suspect the fault is a faulty Fixing coil.
Smelled like the coil was burnt
Haas anybody had a similar fault

[Perfect]

Change Induction Heater board IHPU they cost a little though, or replacing electrical component (transistor, boosters etc )
