York Diamond 80 - burners will not stay lit

I live in the Chicago area. I have a wood frame house.
The gas furnace is 8 years old, York Diaond 80, model # P4HUB12N08001A

When I turn on the furnace, the igniter glows orange, and the burners turn on, but only for a few minutes. After 2-3 minutes the gas gets cut off, and the furnace stops working.

Any suggestions on what may need to be replaced?
Thanks
Jason

 

Yes. I have an idea it is in the venting of the furnace related to what the pressure switch senses.

I just responded to a post, moments ago, below this one, detailing this. We can address this more, if need be, if you come back and ask more questions. But first look at that thread, to familiarize with some of the theory.

IF the blower fan has not come on in about 1 - 1 1/2 minutes of the fire coming on, and actually has not come on at all, the furnace would be highlimiting as the cause. So let us also know if the blower, that blows hot air out the registers, comes on, before the fire shuts off.

Oh. And if you have central a/c and the blower runs and it shuts off, it could be you have clogged fins above the furnace. (Thought to myself: Can't slip up on this one again!)

Also, a dirty filter or a bunch of registers in the house closed down can cause this.
