Automatic 3-Way Fridge: What to do during a ferry trip?

Most modern European motorhomes are fitted with an automatic 3-way fridge/freezer. They are designed to be set on "automatic" and therefore automatically switch to the most suitable source of power as required. We do not recommend switching manually between power sources.

Gas: The fridge is designed to run on gas whenever you are stationary and not connected to a main power source.

Main Power: When connected to power at home or at a powered site, the fridge is designed to run on electricity.

12V (Habitation Battery): Whilst driving the fridge will automatically switch to 12V. This essentially means it runs on power provided by your habitation/leisure battery. As your leisure battery is charging through the alternator when driving, your fridge will not run down the system.
​
Ferry Travel: When travelling on the ferry, we strongly recommend to simply turn the fridge off. Due to safety concerns, you will be asked to turn your gas off and therefore the fridge will not be able to use gas as a power source.

When turned off the fridge/freezer will act as an icebox and maintain a cold temperature. We do not recommend to manually switch the system to 12V as you are likely to drain your energy system and create issues as a direct result.
