Thanks to all replies.
You would leave the batteries connected while traveling. The disconnect is only for extended periods when you don't want the batteries drained due to the parasitic loads.

Propane versus battery disconnect

I understand that. I have an unanswered question.

1) Other posters say they used propane to run the fridge while traveling. If I turn off the battery disconnect, would the fridge use the battery versus using propane while traveling?

Thanks

The refrigerator requires 12 volt (battery) power to work. This powers the control circuit even if the fuel source is propane. Most newer fridges are either propane or 120 volt (shore) power. Switch selects "gas " or "auto " (which is shore power if available and gas if not) . Either way, 12 volt power is required.

I get that now. It wasn't clear to me what you were trying to do.

As mentioned above, you will need 12VDC even while cooling with propane. You probably have a two-way fridge and have no option to use the battery alone.

As an aside, the only fridge that can use 12VDC, AC, or propane (three way fridges) are generally used in Popup campers. FWIW- the 12VDC in a three-way is used only while towing to maintain coolness in an already cold fridge.

You can only use propane while driving unless you have a 3 way fridge.
So battery cannot be disconnected while using propane feature.

I tried this and my refrigerator light stayed on, however I'm not sure it was enough juice to actually keep anything cold or run the pump/motor or whatever powers the actual cooling process. So I don't think it will run the refrigerator, just enough to keep the light on and provide false hope that it's cooling.

Mine keeps just as cool on propane as it does on shore power.
Low battery voltage would affect the operation of running on propane.
Your tv should ..... if hooked up and working properly should charge battery while running down the road.

If not hooked to shore power and not hooked to tv running your fridge on propane with discharge battery.

Also keep in mind 24 hours cool down time is minimum on fridge before use.
And also don't stuff it full of warm beverages that will take all your cooling away.

RV fridges actually run better on propane than electric.

Id second that.

Also double check that the temp probe is in the highest point within the slider
