Curious to what is found. Another thread here today with Atwood problems on a 2015 and I have problems on a 2016 also. Atwood told me to use a slow burn fuse.
Surprised they sent a 20 amp as the docs on all Atwood I've seen to 34,000 BTU say use nothing higher than 15 amp fuse.
My problem is continual fuse blown. They suggested a Bussman 22715 which is a 15 amp slow burn ~~ light blue color. Almost impossible to find locally so I ordered online. They will not arrive until next week.
