WHAT YOU SHOULD KNOW ABOUT YOUR FURNACE:
Your furnace should be cleaned and serviced each year for best performance. Rodents are known to make nests inside your furnace. You must not block off the air vents to prevent this from happening. Also, inside your RV, make sure that there are no rugs or furniture blocking an air vent. This will cause your furnace to limit, which will burn out your limit switch and shorten the life of your motor and other components.
