Hi all.
Have a '09 Fleetwood Discovery 40X, with the Atwood 8531 furnace. The front furnace runs fine. The problem is the blower cycles after the furnace shut down. The blower is to run for about 2 minutes then shut off. It don't. It will cycle not stop, until the furnace is called on again to run. Then the blower will run like it is programmed to. So far, I have replaced the circuit board, and the limit switch. Traced the wiring. Don't tell me it's the circuit boards. I' have tried them in my rear furnace and they work fine. When the furnace is running. No fault light. When shut down. 1 flash every 3 seconds. Air Flow/Limit. I removed the duct work from the rear of the furnace housing. No difference. I'm open for answers. Here's a video. The blower is quite. The gopro makes it noisy.
