RV Furnace Inspection
& Maintenance Tips
The solution? Simple periodic inspection of your RV furnace will go a long way in averting future problems. Just because your RV furnace runs and blows, warm air does not mean some attention may be in order. The older the RV or motor home is, routine maintenance only becomes more important and if it is more than five years old your safety depends on it.Warm beer from a poor cooling refrigerator will not kill you (its really true!) but an inadequately maintained furnace could.
The motor has a shaft running through the center of it with the shaft on the left side driving the main furnace blower and the shaft on the right side driving the combustion blower. Two blowers - one motor. The cylinder shaped mechanism to the right of combustion blower is the outside furnace vent. This is the design of late model forced draft furnace.
Furnace Inspection Checkpoints:
Soot is a byproduct of improper combustion, which means you have a problem. Carbon monoxide is the other byproduct of improper combustion so a furnace exhibiting soot at the outside vent should be inspected and repaired BEFORE being operated again.
Return air vents should be free of dust and lint and should NEVER be obstructed. Remove the return air vent and inspect the case of the furnace to be sure it is clean and free of obstructions. If there is any dust on the furnace, which cannot be easily removed with a vacuum indicates it has been there for a considerable length of time and a cleaning of the entire furnace is in order. Why? Because this dust will be everywhere including the inside of the furnace. Such dust can affect electrical switches, the furnace blower, and the blower motor. Eventually a dirty motor and blower will slow down and the furnace will loose efficiency and if the blower slows down enough it will not operate. (Another safety feature incorporated with the sail switch).
Heat ducts should be inspected at the furnace - first to insure they are properly secured to the furnace AND that they are not leaking. Also, check the condition of the ducting. If it is stiff and brittle, it will be prone to cracking and subsequently leaking resulting in additional operating inefficiencies of your furnace. Such ducting should be replaced.
