Hi all - I have a 2017 Fleet. On some recent chilly nights in Idaho I tried to get my heater going, and whatever mechanism is in there to spark the gas furnace seems not to be functioning. Any advice to troubleshoot before visiting a professional?

When I've had the problem it was because the battery was a little low... low enough that it didn't spin the furnace fan fast enough to swing the sail switch enough to close (open?) the circuit that allows the sparker to spark.  I turned my truck engine on which boosted the battery enough to spin the fan enough...etc.

Stan Kennedy has a You-Tube video on furnace trouble shooting on the Facebook Four Wheel Camper Owners site. Some have had issues with dog hair requiring the area around the sale switch to get cleaned. Some have had to make adjustments to the sale switch. Mark was also right about the camper batteries not having a high enough charge.

If your fridge is running, it can pull down the voltage quite a bit. Wait until the fridge stops to try the furnace.

Is it trying the light (can you hear it click on?) and then not lighting, etc.?   If so, could be the controller board but it seems to new to have that issue already.

I had a similar problem earlier this year.  My FWC is a 2014 Hawk so not sure if this will apply to yours.

 

After checking almost everything I could in the furnace, I pulled the thermostat off the wall and found that it had a AA battery.  Replaced that battery and the furnace worked perfectly.  Apparently the thermostat battery is required to send the signal to the furnace to light.

Start by cleaning the sail switch. It builds up with lint. I would almost guarantee that's your issue. I also have a 2017 and it did the same thing.

Thank you for the feedback. Stan, I will send you an email, and also look into the sail switch issue. I am not hearing any attempted clicks...
