  • Complete furnace replacement

RV Furnace Repair questions we get asked

Why does my furnace blow cold air and never light?
Most often a sail switch that isn't closing because of weak blower speed, a blocked duct, or low battery voltage. It's a safety interlock, not a broken burner.
Do RV furnaces need battery power to run on propane?
Yes. The blower and control board run on 12V, so a weak battery will stop a furnace even with full propane tanks.
Can you service my furnace before winter?
Yes, and it's the right time to do it. A pre-season inspection catches sail switch and burner issues before the first freeze.
