Alde RV furnace fault codes
RV forced-air propane furnaces lock out after failed ignition attempts. Many use a status LED on the control board that flashes a fault pattern.
How to read the code
Find the control board (often behind an exterior access panel or inside under a vent) and watch the status LED. Count the flashes in each group; the pattern maps to a specific fault.
