anything can go bad. Try a controller reboot. And yes, the newer expansion modules fit in the older Pro-C

Can expansion modules go bad?

I purchased a home with a Hunter Pro-C controller which has never been wired up, dated 2005. I wired the controller and the first 3 zones work fine. Zones 4-6 do not work. If I switch the valve wires to zones 1-3 they work ok, indicating to me that the expansion module is not functioning. It also gets warm to the touch a few minutes after turning the controller on. Since this is the first time it has been used and is 5 years old, is it possible the expansion module is defective? It is the grey version. Will the new black version work ok with this controller? Is there anything else I can do before ordering a replacement. Thanks
