Heater not heating

Hello,

First of all, Im new in the rv thing. I just bought a dogde 1978 sportsman and the thruth is that Im completely lost.

I have been trying to turn on the propane furnance. I realiced at first that I dont have any fan for moving the air. Then I tried to turn on the furnance. I was fighting with the pilot for a while until I realised I need power suply for light it. With the pilot lighter I put the termostat high in order to put it warm but nothing happen even the thermo make a sound.

I have been searching about that and I read that can be the pilot sensor or the thermocupula but theyalso say that the pilot should turn off by itself but mine stays with the flame. I heard that i can clean it in order to make it work.

I tried with a knife but not good results. Any help is welcome.

Greetings and thanks.

    Your old furnace probably works this way.
    1. Turn the gas knob to Pilot. Push the knob IN and light the Pilot. Hold for 1 minute and release and the Pilot should stay lit.
    2. Once the Pilot is lit, you turn the Gas Knob to ON
    3. You then turn the tstat ON and the furnace burner should then light, after a few minutes, once the Heat chamber gets hot, the Circulation fan should then come ON and blow hot air.
    4. When the tstat is satisfied, the burner shuts off, Pilot stays lit, and the Fan shuts down after a few minutes of cool down.
    That is how the OLD furnaces operated. What Brand and Model furnace? Doug
