Furnace

See below for several steps to getting the furnace to work:

1.  Do you have propane and is it turned on?
   1. Confirm by turning on a stove-top burner.
   2. If the burner wont light that means there is no propane flowing.
2. Thermostat settings correct?
   1. It’s set to Furnace/Heater
   2. FAN set to auto
   3. Temp gauge is set to desired temp
3. Thermostat have power?
   1. Check fuse in panel breaker box – These are the small 12 volt DC automobile style fuses
   2. 12 Volt power present (car style battery on camper) ? Check lights, fresh water pump, slide-outs, leveling jacks
      1. If no power then you need to plugin to shore power, running vehicle or generator to charge the 12 Volt battery.
4.  Blower Runs but no ignition
   1. Low battery voltage – plugin to shore power, running vehicle or generator to charge the 12 Volt battery.
   2. Propane off or low –
5.  How the furnace works:
   1. Blower motor runs for 15-30 seconds to purge burn chamber of propane
   2. Attempts to light 3 times. Spark, Spark, Spark then a pause. Does this 3 times
   3. Blower speed tuns at about 75% before flame comes on
   4. Blower cycles on 4-6 times and hour or more
   5. Blower runs 45-90 seconds after flame turns off to purge burn chamber and get all the heat out.
6.  Misc:
   1. Furnaces can have operational issues in high altitude areas.
   2. If clean air return is blocked issues can occur
   3. High temp limit switch may have been tripped. Furnace needs to cool for 60-90 minutes.
   4. Loose wires. Connections can come loose during travel.
   5. Dirty circuit board.
   6. Dirty Igniter probes
