Instructional Video
1. Understanding Your Fridge Power Modes
Your Dometic fridge can run on three main power sources:
LPG (Gas)
12V (DC) – For use only while driving
240V (AC) – For use when plugged into mains power at a campsite
An Automatic (AES) mode and a Manual (MES) mode allow the fridge to switch or stay on a selected mode.
2. Powering On the Fridge
Open the overhead cupboard and locate the fridge control panel.
Ensure:
The white master switch is ON.
The fridge switch is pressed down to the ON position.
Press the power button on the left side of the display to turn the fridge on.
3. Switching Between Automatic (AES) & Manual (MES)
Press and hold both the “Mode” and “Set” buttons together.
The indicator light will move to show which setting is selected.
AES (Auto) = fridge automatically selects the best available power source.
MES (Manual) = you manually pick the power source.
4. Adjusting the Cooling Level
Press the Set button to adjust cooling.
Move the indicator to the largest dot for maximum cooling performance.
5. Using Each Power Mode
A. 240V (AC) Mode – Campsites
Plug your vehicle into the campsite’s 240V power outlet using the supplied cable.
The AC light will illuminate, confirming the fridge is running on mains power.
B. 12V (DC) Mode – Driving
The fridge switches to 12V automatically when the ignition is started.
The DC light will appear.
Important:
12V does not cool the fridge — it only maintains temperature.
Do NOT open the fridge door while driving, or it will warm up.
C. Gas (LPG) Mode – Off-grid
Ensure your gas bottle valve is fully open.
The gas icon will illuminate once the fridge successfully ignites and runs on LPG.
6. Warning Light Indicator
If a warning symbol appears, the fridge may:
Not be connected to a valid power source, or
Have an internal error.
Check:
Power source selected
Gas bottle open
Vehicle level
Control panel switches
7. Cooling Time
Your fridge may take up to 8 hours to fully cool on its initial cooling cycle.
8. Common Issues & How to Fix Them
Unlevel Fridge
The fridge must be on a perfectly level surface.
If the vehicle is uneven, cooling performance will be affected.
Overloaded Fridge
Do not overload shelves.
Too many items restrict airflow, reducing cooling efficiency.
