Yeesh..just in time for cooler nights, one of my zone valves appears to work (yellow light glows on the board, then the red light glows). Unlike all of the other zones, neither the pump nor the burner start.

Power must be getting to the board huh? But then what's going on?

Thanks in advance for the help.

    end switch

    I would first suspect that the zone valve end switch is not making solid contact. I realize the light is coming on, but it could be a weak connection. Try jumping the R1 and R2 contacts on the board and see if the circ comes on.
