If you think you are capable of continuing, you could jumper the various inputs the the gas valve one by one until the burner picks up and stays picked up. ![]() Really should call a furnace person especially if you don't have a carbon monoxide detector that you trust. You could have a plugged chimney or exhaust pipe if it is direct vented since there is also a pressure switch that detects whether there is enough draft once the burner picks up. In this case, I suppose you might not have enough gas pressure (is another gas appliance running or is the line to the furnace too small?), a thermocouple probably isn't the problem since the burner wouldn't pick up if the gas valve didn't believe the ignition source wasn't good enough. All Parts Located In The Air Handler Section (Indoor Unit) For parts located in the condensing unit (Outdoor. In your scenario, you have the source of ignition, the gas valve is picking up the burner but the gas valve believes there is something missing so it shuts off the gas to the burner. Concord Furnace Parts, Concord Heating Parts. There must be an 1) electrical/mechanical indication that there is a draft fan running (to move potentially explosive gas so it doesn't accumulate), 2) adequate gas pressure to the valve, 3) the thermostat must be calling for heat 4) and electrical indication that there is an ignition source. I am not a furnace tech but, there are several inputs to a gas valve. SOURCE: my goodman furnace 80703 fan comes on ignitor
