12-volt refrigerator issue 2021 Micro Minnie 2108DS

[dougs]

We recently did our first extended (6-day) boon docking trip with our 2021 2108DS, but experienced sporadic trouble with the Dometic DMC4101 12-volt refrigerator. Usually it worked fine, when on our 12-volt lead-acid battery or when I fired up our Champion 2500 generator. But several nights, with generator obviously off, refrigerator stopped even though our Victron Smart Shunt monitor showed the battery at more than 70 percent charged with more than 11 volts remaining. Manual says that refrigerator should work from 10.5 to 17 volts. The "idiot lights'' in the RV showed no battery power even when monitor showed 70 percent. When I started generator and charged battery the next day, refrigerator worked fine again. So did my battery fall below 10.5 volts, causing the refrigerator to stop, despite what my battery monitor said? Or was it something else? The fridge made a clicking sound one night; I powered it off and turned it back on, which stopped the noise. We're newbies; got the RV, our first, last spring, and haven't had any trouble with the fridge until now.
