    ycav scr trigger boards

    I had posted earlier this year on a drive issue with a ycav wich turned out to be an scr trigger board!!!! Had the same failure a couple of weeks ago on the chiller sitting next to it. Anyone seeing these types of failures, and is there any underlying issues,( component recall ??) Any input would be greatly appreciated !!!!

    did you check your fuses on the transient suppressor board? are they good? the trigger board draws its power from the main power supply...any spikes go right to it unless the transient suppressor board is good and working.
