The older Coleman Presidentials had a screw-cap with mica in the center. You unscrewed the cap and used a telescoping match holder to reach in to the thermocouple/pilot light and lit it once you twisted the gas control to the 'pilot' position and depressed the controls button or lever. I don't know the specifics on the newer Preidentials Chester, but it has to be similar.

Sounds like the flame sensor. But it could be the thermostat. Is the furnace standing pilot or electronic spark or hot surface ignition. I would start by checking thermostat. Turn power off to furnace take thermostat off wall and take wires marked r & w and connect them together. Turn power back on if furnace works then change out thermostat.Most eclectronic ignition Furnaces have a flam sensor, You could take flame sensor out and clean it up with steel wool or wire brush. If you need anymore help just reply back .

Is this furnace standing pilot or electronic ignition. If standing pilot i would check furnace filter then the thermastat. To test themostat first turn power off to furnace. Take thermostat off wall and take wires labled R & W and connect them together. If you have electronic ignition I would start with cleaning the flame sensor with steel wool or wire brush.If you have and more questions i will be glad to help.

It could be a bad temp sensor that tells the fan to come on when the heater reaches a certain temperature or it could be a bad fan motor. Take a 12 volt jump start box and hook it directly to the fan motor to see if it will spin. If it does not the motor is bad and if it does you have to replace the temperature sensor in the heater.
