Hello, send me a photo of the units wiring diagram glued to the inside of the furnace access panel, photo must be well lit and *exceedingly well focused. and a photo of the printed circuit board where the wires from the thermostat attach.
I will mark those up with trouble shooting instructions.
Use the attach files link next to your send button to attach the files
The odds of you fixing this without parts in the snow however are minimal... you should have plenty of back up heat available, such as a few portable electric space heaters or a kerosene heater (use only with a window cracked open 2")
Thanks, ***** ***** the diagram

If you have 24vac between R and C with the blower door switch held in, put the blower door back on and turn the thermostat OFF at the thermostat, wait 5 minutes then have someone else turn the thermostat back ON and set the heat to 90F as you stand next to the furnace listening intently for the following in this order"
Small induce fan comes on
in 2 seconds you hear a faint click, and inducer fan continues to run
in 30 to 50 seconds you hear two faint clicks as the igniter relay closes and the gas valve relay closes
next you hear the burners ignite.
If the burner ignites tell me how long it stays lit until it goes off.
You may want to repeat this test a few times to get familiar with the sounds.....I can tell from what you hear far along the furnace is getting in its firing sequence and from that what the problems are.
Hello again, the printed circuit board is most likely bad, but there can be other problems.
Connect your volt meter to the female side of the igniter plug, and if you get voltage there. Next repeat the test but at the wires that connect to the gas valve, tell me what you can discover.
If you can take a photo of the wiring diagram glued to the inside of the blower service panel I can mark it up with trouble shooting instructs,. photo must be taken close up and exceedingly well focused... us the attach files link to the left of your send button to get that to me.
We can go from there
