Smile Suburban Furnace in Elevation 3612

Still new here but the learning continues and I want to be sure I share what I have learned for others.

I have a 2014 Elevation 3612. Two nights ago, the original installed suburban furnace did not kick on like it was supposed to.

At the thermostat, the heat was on with fan on auto and when it was time to kick on, all I could hear is the blower for about 30 seconds, then it kicked off.

I tried to troubleshoot it myself:
- Checked propane level, GOOD
- Check propane flow by igniting the stove, GOOD
- Ensured I was not in lockout mode by cutting shore and battery power for 5 min, GOOD but still same result.
- Checked battery for ample voltage for furnace to ignite.
- Checked air flow (ample, no mud dabbers or dust/hair in exhaust)

...this led me to believe it was the sail switch which activates the igniter. I have no mechanical background of any kind.

So, I made a call to my local mobile repair guy (who was fantastic by the way and if anyone needs one in the Maryland area - PM me and I will get you the info). After he troubleshot the unit, he determined it was the sail switch.

Took them some effort to get to the unit through the storage in the other side of the unit. They pulled it, checked it over and replaced the sail switch.

Happy knowing that I will be warm tonight Hope this helps someone who might have the same or similar issue!
