Hello again! So we have now purchased our new 2014 19 rd and have parked it at home. We left it unplugged last night and today and then we plugged it in to our home and when we did a noise began, almost like a hum or a fan from the mechanism just below the stove, I think this is the furnace, (please don't laugh this is my first trailer
) so anywho there is no air from the vents and the thermostat is set in the off position. I have no clue why this noise is occurring please help! Thanks
