i have a ruud gas furnace M#UGTA-10EZAJS. On startup both blower and inducer motor runs, but after so long no ignition happens gas valve doesn't energize and open and hot surface ignitor doesn't energize. I know the air handler blower should not be starting just yet. gas valve or hot surface ignitor is not getting proper voltage. I also notice a small crack in the hose from the negative pressure control to the inducer motor. I don't know if im over looking something or what?
Any answer or tips would be greatly appreciated. thanks.
