2019 prowler lynx sail switch


Does anyone know of any resources to walk me through accessing the furnace sail switch. Furnace blower will kick on and stop after 30 seconds without igniting. I figured I would start there. Access is a little tight. I thought I would ask before tearing things apart.

Up top under the TOOLS bar you will find:
Heartland Owners Manuals
on the left go down to HEATING/COOLING
click on FURNACE
choose which brand you have installed Atwood or Suburban
this is a good starting point
