    One section will light, can change to 2, makes noise as if in a draft, on changing to 3 the flame goes out and the pilot light fades. the spark electrode glows red at that stage.

Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken

I would have the ignition control board replaced. That is what tells the gas valve to come on and if there is flame or ignition it will keep the gas on if the flame sensor gives the board a signal that the burner is lite. By you shuting power off and on to the furnace it resets the board and it will go through its cycle again.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Blower works but no heat


If in fact you have the above listed furnace, you do not have a pilot but electronic ignition. You will need to remove the front cover on the furnace, tape down the door safety switch and then have someone help you by turning up your thermostat to a very high setting. Watch and listen inside the furnace. There should be some blinking going on at the control board followed by a small blower fan starting up. Then after 10-15 seconds there should be a click followed by an orange glow viewed thru the viewing window to the burner section. In a few seconds the gas valve should click and the burners will ignite. There is a safety switch that will sense flame and then keep the gas going to the burners. If it does not sense it, it will shut it off within 10 seconds. If all is well so far, your blower will turn on in about 90 seconds after flame. There is a diagnostic code chart on the back side of the access door if you get an error code (blinking) on the control board.

Always check little things like air filter, condensate drain and broken or loose wires.

Duct fan comes in, igniter lights, but no flame


Remove the front panel. Tape the door switch to the closed position. If the thermostat is calling for heat the furnace should do the following: a light on the circuit board will flash and then the exhaust blower will start. A few seconds later (10-15) you should hear clicking at at the circuit board and an orange glow should be seen thru the small viewing port. A few seconds later the gas valve should open and the orange light will turn blue. If the blue flame only lasts a few seconds and then goes out, their may either be a blockage not allowing the flame to travel to all the burners and not allowing a flame sensor to sence flame, shutting down the unit. After a few cycles of not starting, the circuit board will flash a series of codes that you can read if you look on the back of the front cover. It will give you a starting point where we can research and come up witha more difinitive answer. Let us know what you find for codes.
