I have a gas furnace. House is 55 degrees. Thermostat is set at 80 degrees, switch on furnace is in on position and fan/blower works, Gas is present in hot water heater 24": away on same line and stove works in kitchen. Breakers are OK.

Furnace does not light. No gas smell. Help!!

Thanks

Could be gas valve,, could be limit switch, could be pressure switch, could be igniter, could be several other things,, u need to watch closely more info needed, tell us after looking up close what's not working

Do you have a pilot or electronic ignition?
