Headed out on camping trip tomorrow and noticed today that the 3 way fridge on my 2017 320s isn’t working. Have read several posts so while I try to troubleshoot this, can you tell me what the three fuses accessed through the stove top are for? Unit is getting power, small green 110v light is on, but no cold. Will chk if it works on propane tomorrow. Wondering if any of those small fuses would disable cooling if the green light is lit. Thx

    @Explorers2, how long are you letting the fridge run before deciding it isn't cooling? It is notoriously slow to do so. I will begin my cooldown usually 48 hrs before departure. It takes 24 hrs before significant cooling is apparent and even longer if the ambient temperature is high.

    Short answer:
      -   120VAC On indicator will not light if the AC circuit fuse (under stove)
                         located on Fridge top is bad.

    Longer answer:
       -   Your Fridge owners manual should include a simple wiring diagram showing the fuse functions.
             If you do not have a manual one can be downloaded from web.
       -   For the Fridge models 3136 and N180 there are fuses on Fridge top for:
                120VAC circuit, 3A fuse
                12VDC circuit, 20A fuse
       -   The model 3136 also has a fuse for the electricity powered Relighter,
                 it is a 1A fuse on a 12VDC circuit,

    Yes that’s what I figured. On indicator light is lit so that fuse must be ok.

    Ok seems to be getting cold or at least cooler, so it’s working. Either it just takes forever to get going or fiddling w the dials did something good. Either way it’s working at the moment. 

    Does running it on propane cool it down any quicker than 110?  Also how long will it keep cold using a tank of propane?
