Greetings,I have a tempstar furnace model ntc6075fba1,s/n l984128725, the pilot lights, then the blower comes on but the burner does not come on, then when the thermostat is turned down the blower continues to run.please inform me of the problem.Thank you, Albert.

It sounds like you are having trouble at the gas valve. Check with a volt meter to see if you are getting 24 volts to the gas valve. If you are then I think the valve is bad. If you are not getting voltage to the valve then it could be the limit or fan switch. Or it could be different things depending on what kind of pilot system you have.
