Atwood furnace problems
I have a 2011 coachmen freedom express with an atwood furnace. After dewinterizing i tested furnace before we went out and it worked fine. After about five hours at campsite we noticed it getting chilly and then upon listening to furnace i realized i could hear the ifnitor attempting to fire but no heat. How can i get to the ignitor to check it or could there be other issues. Yes, the fridge and stove both work fine.
