Didn't a contactor come with your Curtis 1238? Mine came with the LEV200A6NAA one. And it takes 48V on the orange wire with white stripe. And the blue wire with white stripe is the coil return.

I remember being surprised at that when I found out. I was expecting it to be 12V.

*I haven't actually measured it in real life to make sure it is 48V however.

Why would that part go bad so quickly? And did the 48V version go bad?

Here is the part number of the one they currently recommend, should I replace mine before I even use the old one? GIGAVAC Contactor Part# GV200QA-1
