I have an older gas furnace with basic thermo. I can get the pilot lit while holding the pilot button down but within a few seconds the pilot fizzles and goes out. I can even turn the valve to on, pilot will stay on for a few seconds but befor I can get to the thermostat to turn it on, pilot fizzles. When I try to relite, no gas from pilot. I can wate a feww minutes and pilot will be at full pressue again. Help, Rick
I slept on this problem overnight. I know that when you hold the pilot button down it is manually opening gas to the pilot, so there had to be a blockage to the valve. Maybe bad regulator outside? Went outside to check and found the gas line shut off. Turned on again, lit pilot, good flame working fine. Now, that valve was off all sumer but was allowing enough gas through to let pilot lite for a second or two. A little scarey don't you think???
