It will not work on 12volt unless the engine is running is that what you mean as that is correct and just to keep things cool

Caravan fridge/freezers will only work on 12v if the engine is running. This is operated via a relay and although if you wanted to you could do a rewire job it would be a bad idea as the fridge will draw around 15amps continously from your battery. In addition there is no thermostat on the 12v element as it is only designed to be used when you are moving. When stationary it will work on mains if you have hookup, otherwise on gas.

as John said, it will only work on 12v with the engine running and will only maintain the pre-cooled temperature...not powerful enough to cool it down.

on auto it will select the appropriate source in this order.

230v
gas
12v (engine running)

So....

if on hookup it will use 230v mains....by default.

if no hookup it will use gas.

if no gas it wont work until the engine is started.



if you want to override this you need to manually select the power source.

I have had quite a lot of vans in my time and on most I have found the fridge actually gets colder faster when driving (running on 12v) than on gas or mains when stationary. I suspect this is due to a certain amount of forced ventilation due to wind rushing around the vehicle.

I have a little thermostatically operated fan in my top vent and have been maintaining temperatures of -16C in my freezer with outside temp in low 30sC which is pretty good for an absorbtion fridge.

ok thx all i have now found out on auto it wont do gas if no hhok up and no engine on but if i manually change to gas then turn off the fridge freezer once i turn on again it is ok on gas i think it has a mind of its own lol

If it's an AES fridge it will not automatically switch to gas until the engine has been switched off for at least 15 minutes and sometimes longer.

This is so the gas cannot ignite when you stop at a filling station to refuel.
