furnace fan
Put my fifth wheel away for the winter and the furnace fan won't shut off. No propane on, just battery. Any ideas what the cause might be?

Thermostat set to the fan on function?
RV furnace fan is NOT controlled by the wall tstat Fan setting. The usual cause of this is the Hi limit switch stuck closed. Another long shot would be water corrosion on the furnace circuit board fusing the fan relay. Doug
