Are you getting any (controller or heating unit) errors? I found that if I had an error (in my case always a non-critical, nuisance type error), that error needed to be "cleared" and then I was OK to start.

I was also more likely to have one of these nuisance errors when going up to elevation and then trying to start my Espar.

Myself, also in Boise ... saw these errors when driving up to Bogus or over to Anthony Lakes, both relatively high altitude - but not THAT high. Additionally, your device should be the newer models that are adjusted to deal with high altitude.

Van build and research involves so much YouTube that I bit the bullet and started paying for it. You might want to consider it. It's a tiny fraction of how much you end up spending on the van and the improvement to the quality of life is substantial.

Whenever my espar "wont work" I have cleared the error codes and / or pulled the breaker for a full "reboot" and it has come back to life. I usually have to do this more often early in the winter ... after which it seems to work better for the remainder of the season. I'm mainly using it at 7000ft elevation for the last 3 seasons, no problems beyond what i stated above.
