Have an older Carrier Gaspack with the original Dual valve gas assy. Replaced the original J/C G600XL with a Honeywell S8610 univ intermittent pilot ignition module. The system still has the same following problem. After heat cycle the main burner shuts down, but the intermittent pilot remains burning - with no voltage across the coil. In this state a further call for heat from the thermostat will not turn the main burner on. I have tested the valve coils out of control circuit and both actuate with 24Vac across them.
So at this point I can only beleive that the Valve body has some sort of leak internally to feed the pilot regardless of the state on the valve coil.
Any help as to what my next step should be ?? Replace valve ??
Thanks UpsMan
