We are in a 2017 3820FK, in Central Fl and needed heat this AM. Nope, the furnace will not come on. Plenty of gas, stove, hot water all work. Select Auto and Furnace but nothing, no blowers, no fire. I do get a single flashing light on CB, 3 sec pause and another single flash, repeat. Error code says Air Flow Limit Fault. Pulled the cover off and pulled the tube out, no obstructions. I am "nearly" 100% certain it DID work last year. Any suggestions? Also, how do I access the heater return? Where is it? Assume the floor registers are heated Air "into" the coach.
