The Dometic
fridge has two fuses. One in the trailer's converter panel on the 12 VDC fuse panel, and another one outside, accessed by removing the lower outside
fridge vent cover. Incidentally, fyi, if there is no 12 VDC power to the fridge's control board, then no workie in any mode, (12 VDC, 120 VAC, or
Propane.)
(As an aside, I've been to Moclips, Pacific Beach, Quinault, and most of the other venues out there in your neck of the woods too. I love the ocean.)
