From time to time I have to re-light the pilot on my 1966 gas furnace.
Tonite I noticed the temp was low and re-lit it.
Just now I checked again and temp is 69, with thermostat set at 70.
Went to check furnace before going to bed.
Pilot is lit, blower running. So I thought, its still in cool-down mode. But THEN I realized that if so, the house temp would be ABOVE 70.
So is it possible that the old pilot is not igniting the burners sometimes, and eventually the valve shuts the gas off and the blower stops?
I got my long-necked lighter and ignited the lighter and moved it towards the burners, but I blinked or looked away or just didn't llok closely enough and I don't know if I lit them or if they were already lit but the fan still on low.
