Refrigerator voltage

I know my refrigerator needs 12v to run.what I'm wondering is at what point does it stop.Does it stop at 12.0 or 12.3 or will it go into the 11's say at 11.8.I'm thinking when I'm camping and running the tv and lights and the voltage drops at what point will my refrigerator stop . My tv goes into the 11 volt range and still operates so maybe the circuit board in the fridge might have a wide range . My manual does not say anything about it.

At 11.8v, you are at about 35% of your batteries charge. Taking it below 50% is going to shorten it's life if you do it very often. 50% is 12.06 volts.

I think he might be referring to the shut off voltage of the PCB and controls that he might incur while running other appliances and equipment and the batteries are under a heavy load. In those instances the voltage may temporarily fall below 12V and even into the low-mid 11's.

I can't offer a number voltage-wise at which a fridge might shutoff at. I can tell you most 12V DC equipment with 12V nominal voltage has a variable input of +/- 15-20%. Electronics can be even wider in some cases. This doesn't mean this always the case. But incandescent lighting inside you coach for instance will run anywhere from 10.5 to 14.5V Too much lower than that and I doubt they'd light and too much higher and they'd almost certainly blow.

But as the Site Team said, be mindful of your voltage when boon docking. Running your batteries below 12V for extended periods will kill them in relatively short order.

The lowest my batts have been is 12.3. What if I fell asleep with some lights and tv on and it dipped into the 11's I was wondering if my fridge would shut down. I guess I could call dometic and see if they know.I hate calling them as its always busy when I call.

They would be your best resource on this. But by the same token, I would think the worst that would happen is your fridge would shut down. I wouldn't think there would be any lasting harm. And if you caught it in time you could just connect to your TV for a while to charge the batteries.

I'm hoping as soon as the voltage come up the the refrig resumes normal operation with out to much trouble. I wish my model would defaut to a run mode like some of the other models.

I just got off the phone with anthony at Dometic and he said 10.5 volts is when things get erratic and start shutting down,the lights will start to flicker .Once you restore power you will need to press the buttons and get back to auto or gas. To me this is good to know.
