View Full Version : Gas Furnace won't light

I have a Coleman gas furnace, approx. 8 yrs old. It burns propane gas. The gas was turned off at the supply tank for about 5 months. The tank has about 15 % gas in a 150 gallon tank. The shut-off valve on the furnace is on. The thermostat is set higher than room temp. I turn the unit on and the igniter glows red for about 15 20 sec., but burners do not light. Could the gas line have an air block ? Any suggestions would be appreciated.


Thanks

That, or as Grady suggested in a similar thread the other day, that perhaps an insect built a nest in the gas distribution somewhere. What to actually do about this situation, I'll leave up to one of the furnace guys/mod.
