There is a LED code light on the motherboard giving the code 33.
I have checked all vents, exhaust and even changed the filter (that was only 15 days old) The sequence is spot on...

(bare with me as I don't know the termonagly of the parts I'm about to discribe)
Ok... I turn the thermostat on and it sends for heat
The round coil looking thing spins
The glow stick... (on the first burner on the left glows)
The gas turns on and the flame shoots out blue flames on all 3 burners
The flame rod (witch I have removed and cleand with light grit sand paper) starts to glow red.
One min latter the blower turns on
Two minutes. Latter gas shuts off
The round coil looking thing stops spinning
Blower runs for about 5 minutes and it starts again

Sorry for the poor spelling and the backwards way of describing things but Im just trying to say everything I see to get any help at all. Thanks for taking the time to help me out.
