Furnace:recreational vehicle
Defect Summary
Overheating and premature deterioration of the combustion chamber can occur in marginal or poor installations of the furnace. The deterioration is caused when air circulation from the furnace housing is restricted either by a lack of return air circulation or a ducting system which prevents free circulation of the heated air from the furnace.
Safety Consequence
If the combustion chamber deterioration is not detectedand corrected, chamber flame can penetrate the chamber and the furnace casing,causing a vehicle fire.
Corrective Action
Inspect the combustion chamber and test installation of the furnace for specifications. Rewire the overheating limit switch, which cuts the furnace off when the heat exceeds the specified limit and automatically resets the furnace to a configuration which requires the operator to manually reset the furnace.
