Atwood hydro flame 8500-IV series Furnace does not light. Blower comes on for about a minute then stops. I can smell propane at the unit while the blower is running. I do not hear a clicking sound,so I'm assuming no ignition. The circuit board diagnostic LED indicates a "Flame Sense Fault".
I removed the ignitor. It looked new, apparently the unit has not been used much here in south Florida. I cleaned it and checked the gap at 1/8". I checked the voltage on the ignitor and got 12v while the blower was on. Seems like it should be greater than 12 v to spark a 1/8" air gap.
Any Suggestions??
