Hi all,
Trying to get the ALM LED to turn off to get the R53c relay on. We have replaced the DPP-210 firing board with no luck. Leaning towards the IGBT,s being faulty. Wondering if we’re on the right track? Wondering if there is another reset besides FFFF?

I have a manual as well which’s leads us to the IGBT,s.
Anyone have a solid way of determining which IGBT is bad? If not all of them?
