Can you please explain why this is not a valid test?

It is a valid test. Propane is the same regulated pressure throughout the entire system. Once it leaves the regulator and goes to the black pipe manifold, there are no cutoffs, valves, or solenoids until it gets to each of the individual appliances.
As to the OPs problem, the furnace is controlled by 12VDC. If he hears no noise at all, that means the fan is not running either because of no 12VDC, a faulty controller, or a faulty fan. He should read 12VDC from the thermostat the furnace. That's what is switched from the thermostat. If 12V is there, then the problem is most likely a bad control board. If not, then the heater portion of the thermostat is bad.
