Hi try jumping out the pressure switch see if it lights and check th rair filter might need a clean
I also have a York Stellar we've had our for 10+ yrs, first owner, started up a week ago, worked perfect, Now that's it's getting cold it stops heating. Can't get no flame, no fire, nothing crept that fan runs non-stop. Purchased new igniter for 62.00 which was a waste of money.HELP
I think I found the common problem to your headaches with these units, yesterday I got fed up with the unit and decided to clean the inside of the heat exchanger I removed the inducing fan the plate over the heat exchange and vacuumed blowout and cleaned all the insides it seems that it gets clogged up and doesn't allow the furnace to vent properly which causes a backflash which then turns the unit off this has been happening to me for a long time now if you're experiencing the same problem it's not hard to do just take some time patients and being very careful not to break anything I'm also considering putting in a brand-new inducing fan while I hope this helps my fellow York furnace owners

YORK GAS FURNACE NOT STAYING LIT???
I have a York Stellar Plus Gas Furnace installed on March 18 1994.
Upflow Model Direct Vent Furnace
Model # P2UDD 20N0 9501C
Serial# EMB M431099
The thermostat is sent to Auto and Heat. The Inducer fan motor turns
on, then the hot surface igniter begins to glow. The gas valve kicks
on the unit stays lit for 1 second and the unit cuts out. Then the
unit attempts this process all over again. The units main burners do
not want to stay lit so that the blower motor can turn on to blow
heat.
This has happened two times in the past two months and I have changed
the flame igniter and flame sensor. I changed the furnace control
module 50E47.
This has happened twice and when I changed these parts the unit worked
fine. Now it happened again, I don't know why or know what to do??
Please help me.
Thank you, Adam
