Can you give me complete model from inside furnace in burner compartment so I can provide guidance with this specific unit.Model will be on a label just above burners on right or left inside panel
OK lets make sure, 3 short and then 1 long> The short should blink first
OK if the shorts is 3, that is correct. Turn power off to furnace and back on, See if code goes away. Then call for heat and see how far in lighting sequence it will go and if we go back to same error code.
Yes lets do once while we are troubleshooting. Tell me if inducer vent motor comes on and if wind has now died down
OK is the small vent motor indeed coming on when you call for heat? It has to draw a vacuum on pressure switch
Look near vent draft hood ,around burners and on blower housing and see if you find an auxiliary limit that may be tripped.Button in center will push in to reset if so
Just push in. If neither clicked they were not tripped. Next I want you to locate the pressure switch. It will be a small round canister with a hose attaching it to the inducer housing. Remove hose from inducer housing and leave it attached to the pressure switch. Power off and back on to reset board again, Then call for heat at thermostat. Allow inducer to start then suck on the end of hose still attached to pressure switch and see if switch will close and burners ignite.

OK you may not have a hose If switch attaches to inducer housing.Do this. Allow inducer to start and then jump the yellow and orange wire together to see if burners will light
The furnace has to sense that switch is OPEN before inducer will start the sequence,Once it does we can jump the switch out.
Yes, using a jumper wire or a pair of needle nose pliers
That is fine. Issue can be bad switch,blockage in vent or issue with inducer blower wheel. I have seen small birds and once a lizard in blower when prevent vacuum from closing switch.

Yes I am here.
I am wondering if maybe there is something in that inducer. Is it hard to remove to check?
It has a little blower wheel tat carries out exhaust and keeps a vacuum on the pressure switch
Does that motor stay running all the time you are calling for heat?
I am wondering if maybe the inducer is not pulling the exhaust out
That fan has to come on to close the pressure switch
Yes it is often hard without actually being onsite

Ok we are going to have to verify the inducer is sucking a vacuum on the pressure switch, Does yours have a little rubber hose between inducer and pressure switch or is the pressure switch connected directly to inducer?
