    • 1). Inspect the RV or camper electrical panel for damaged fuses and tripped breakers if the burner does not ignite and the blower fails to operate. Replace fuses with others of the same amperage and reset any breakers as necessary.

    • 2). Check to see if there is excess ducting or bends and kinks in the system if the burner keeps cycling on and off or the blower runs continuously while the thermostat is in the ON position. Make sure that the furnace is secured properly and the vent fully terminates to the outside air. Check the vent for any buildup of soot. Blow the vent with compressed air if necessary.

    • 3). Clean or replace the pilot orifice if the pilot light will not light. Check that the electrode is positioned properly over the burner. Make sure there is propane in the bottles.

    • 4). Set the gas pressure to 11" W.C. while all the appliances are running if there is insufficient heat coming from the unit.

    • 5). Check all gaskets for signs of deterioration. For safe operation of the unit, gaskets need to be secure and tight. Replace the gaskets if necessary.
