Is fridge on 12 volts?
We have a 2004, 3295 Montana. Husband wants to know if the fridge runs on 12 volts? Or is the 12 volts only for the gas operation? He was on the outside, putting a screen there to keep wasp out when he happened to see some of the equipment had 12 volts listed on it.
Thanks

Dustytuu,
The 12 volts supplies the "brain", or the circuit board that tells the frig what to do. The frig runs on propane or electric, the 12 volt is there to help you along when you are not hooked to shore power.

Thanks to all. Now we know. We thought that was the case. Never heard of any that ran on 12 volt.

Some refrigerators in RV's are 3 stage. AC/Propane/Battery. Our other unit had this type. If AC or propane is not available, it will run on battery. However, this is a really quick way to run your battery down.

All of the RV style (absorption cycle) refrigerators use 12V (and only 12V) for the control circuit (electronic thermostat) and interior light.
The other powered part of the refrigerator is a heat source. This heat comes from either:
A) Propane flame
B) 120V Heating element
A three way refrigerator also has:
C) 12V Heating element
However, the 12V heating element does NOT provide as much heat as either A or B. It is really more of a "keep the interior of the refrigerator from warming up too quickly" thing for travel during the day. It is more useful while you have the alternator of the engine available to supply the electricity. It isn't intended for use while parked in a camp site.
So, for our two way refrigerators, if you have it switched to 120V use, you are actually using 120V (for heat) AND 12V (for control) at the same time.

You have to have a 12v source either through the battery or power converter for the refrigerator to ignite the propane heating element.

Doesn't the 12v control board also make the decision to try to use gas or electric?
