Your pilot orifice could be plugged not allowing a gas flow for the spark to ignite.

So you cleaned the pilot orifice and there is still no gas flow?

Did you just have the propane tank filled?

Did you bleed the Lp line going to the furnace?

Look at the pilot assembly area. See if you have a 3 wire pilot. The wires go into the safety switch mounted with the pilot lite.


I cannot find your model number on the Bryant site.( your furnace could be to old) The closest one is below but it is showing HSI ignition which you said you have spark ignition.

Does the 3 wire pilot shut off the valve(gas) if the pilot is not lit? If so I am thinking the pilot is bad and not opening the pilot's gas valve, but I don't know for sure- I'm a paint guy not a doctor ;)

No ,the propane guy told my wife there was 30 gal when he filled it and he did not bleed it

If you had 30 gallons you do not need to bleed.

I am still searching for your furnace to be sure what ignition source it uses and a wiring diagram.

We need to find out if there is pilot gas going to the pilot when the furnace calls for heat.

Normally the pilot remains on when the burners are running

We need to find out if there is pilot gas going to the pilot when the furnace calls for heat OR if no gas is present at all at the pilot
