Your furnace should be the 35 series. It’s fairly straight forward to trouble shoot. Your last response states fan doesn’t run
If fan doesn’t run you need to verify there is 12 VDC to the fan wires and you can temp jump 12 volts to fan ... if it runs then blower motor is good and your issues lies downstream.
..sail switch
.. hi limit switch
.. control module
.. loose wire
