Sounds like I'll have to if no one here knows but I hoped to avoid opening the unit one more time just for that
I didn't realize it when I opened the unit to take the above picture assuming all I needed was the big part number, but looking at online pictures there should be a label next to the coil terminals with the voltage printed, so that's another option if I can see it without removing the whole thing.
Any opinions if changing the contactor is likely to help? My hunch it has something to do with not enough current from the control circuit to get positive hold, as contactors are pretty dumb devices, they either work or not, and the problem here is intermittent.
