Suburban furnace fan cuts off prior to ignition - sail switch?
Tried turning on the wall furnace for the first time this season. The fan turns on but after about 15 seconds the fan cuts off. From my research it seems the sail switch may be the culprit. Propane is turned on and stove/fridge are working fine. Is this a fairly straightforward process to remove the furnace to investigate and inspect/replace the sail switch? Does it pull out from the interior of the rig? Anyone who has tackled this repair and can offer advice would be appreciated!

Mine was an '02 but probably not much different. Access to the sail switch is from the outside by removing the outside panel which might be a little tight if it's never been removed. It's easy to replace. The screws are quite small and elusive. Be careful.  Got the sail switch on Amz I think.

This is the only area at the vents that relates to the furnace. I assume I should be trying to access from the inside or do I take this small vent panel off?

Looks like things have changed or it's different on the RB which means someone else will have to chime in. You can see on the photo of mine that the heater exhaust vents are in a rectangular panel which has a screw in each corner. The screws are removed to access the heater.
