SC 553 on a RC4500

[rednecktech]

Maybe during the process of removing and replacing the thermopile some other harness got pinched/pulled. Did you have to remove any other connectors to remove the thermopile? If so, a bent pin could have occured when reseating one of them. If no good, the next step is to us an M80 to blow everything back into place.

UPDATE: Machine is fixed. Technician was going over harnesses and two of them "clicked" into place. SC120 went away.

Machine goes back to customer tomorrow. So, what ultimately fixed the SC553 was either the thermopile or the IH Coil pcb. Thanks again for all of the help/suggestions.
