First of all the fan switch is only for the A/C unit and does nothing for the heater.
If the heater fan runs for when you turn the heat on but doesn’t light, it’s either not getting propane, the igniter is bad the sail switch (which detects the fan running) is bad or the control board itself failed (less likely). Before all of that, is your battery fully charged or are you plugged into shore power (I assume so since you ran a space heater)? If the fan doesn’t run fast enough it will not attempt to light.
