Furnace not igniting

Furnace will not ignite in Rockwood Geo Pro. Outdoor temp is 23F with windchill at 17F. Installed battery, propane tanks, purged gas on stove and it fired. Hooked up Honda 2100 generator. Everything onboard works except the furnace. No sound of igniter. Any clues?

It is cold here and the only reason for setting up the TT was for a place to take the DW for a surprise dinner. Any tips will not be tried until spring when the weather permits. The TT is stored at an outside storage facility.

Thanks for any tips.

When you turned on the furnace did it blow any air out the registers/outside exhaust?

This is a process it must accomplish (and prove out to the control board) before it will try to ignite.

No air moved. No sounds of any kind. Dead.
Outside air intake and exhaust were uncovered. Digital thermostat was placed on “heat”. Turned off thermostat and waited one minute and tried to start again. Did this several times.

Sounds like no 12v to the furnace or the thermostat didn't actually turn it on.

Did you check the furnace fuse or for voltage at the furnace itself?

Did not. Will put that on the list to checkout. Thanks.

Not sure about your digital thermostat but on our slightly older TT, some issues can be resolved by reinitializing the thermostat (instruction manual for the thermo should tell you the reinitializing steps)

The furnace started today. Checked nothing just turned on the thermostat and the blower ran and then the furnace ignited. Outdoor temp was 45 F and inside temp was 56F. Have no answer why blower did not run and furnace did not ignite in February. Anyone have any clues?
