RV Furnace Operation & Preventive Maintenance
In this RV video, RV expert Mark Polk discusses the basics on how an RV forced air furnace works, and some RV preventive maintenance owners can do to make sure the RV furnace is operating properly.
Top Tips from this Video
- The majority of RV furnaces are direct spark forced air furnaces with a sealed combustion chamber that is vented outside
- The furnace operates on 12 volt DC power from a battery or the RV’s converter when the RV is plugged into electricity
- Inspect the intake and exhaust vents on the furnace for obstruction
- Some insects are attracted to the smell of propane and may build their nests in RV furnace vents – have these cleaned by an RV service center
- Check for any signs of incomplete combustion such as black shoot in the exhaust vent
- Causes for incomplete combustion are obstructions in the exhaust vents and/or a dirty gas burner – always check this yearly
- Inspect the return grill inside the RV and clean it using a vacuum cleaner
- Always make sure nothing is blocking the return grill
