Absorption Fridge FAQ
|What is MES?||This is Manual Energy Selection. The user must select the energy source desired.
Caution! The fridge should only be used in DC mode while the vehicles engine is running, otherwise the battery would be discharged very quickly.
|What is AES?||This is Automatic Energy Selection. It automatically searches for DC then
AC and then GAS.
|When switching from
DC to GAS operation,
it doesn’t switch
(AES model only)
|There is a 20 min delay when switching from DC to GAS (i.e Petrol Stations)|
|The cooling unit has
failed on my
refrigerator can it
|Cooling unit leaks are often detectable by a yellow crystalline or staining or a strong ammonia smell. If there is a strong smell is within the vehicle open windows to vent. It is not possible to refill the cooling unit but it can be replaced – there is no need to replace the whole fridge.|
|If I have a MES or
AES fridge do
I need to be
connected to a
|Yes the fridge PCB needs to be powered.|
|Does the light go off
when the fridge door
|How should I clean
|We recommend the use of a soft cloth with luke warm water with mild
detergent. Then wipe out the appliance with clean water and dry
thoroughly. Do not use abrasive cleaners.
|When shouldn’t I use
|• At petrol stations
• On ferry boats
• While the vehicle is being transported
• While travelling in certain countries (check local regulations before travel)
|What gas pressure
does my fridge
|Please check the dataplate within your fridge.|
|Can I service my
|NO! All gas and electrical work MUST be carried out by a qualified and competent engineer.|
|Can I use my fridge
to store medicines?
|No, the fridge is to be used solely for the storage of food.|
|How can I
to make my fridge
|The freezer is held in place by 2 catches located under the freezer shelf.
Slide the catches toward each other and pull the freezer compartment towards you.
||• Maintenance is the best insurance to long life of the fridge!
• Before placing your vehicle into storage or if you are using the vehicle for
long periods, we recommend emptying the condensation pot located at
the rear of the fridge. You can always extend the condensation pipe to
exit through the lower vent but be aware this will cause water to drip on
• Always ensure the fridge door is closed and locked before starting your
• Don’t over pack the freezer or fridge as this will reduce air flow and lead
to uneven temperatures within the fridge and freezer.
• When placing your vehicle into storage we highly recommend making
sure the fridge is clean and dry and that the door/s are placed into the
vent position (refer to operation manual).
• When defrosting, never forcibly remove ice or use any means to
accelerate the defrosting e.g. heat source.
|Before contacting an authorised Service Centre or a DAN engineer please check below for a possible remedy:
• The instructions in the operating section of your manual have been observed
• The refrigerator stands level the tilt angle for single door fridges is 6° and for double door fridges is 5°.
• Try running the unit on a different power source if available i.e mains or gas
• Is the ambient temp within the set range? i.e below 10 degrees use winter covers, above 32 degrees
the fridge may need - ventilation fan kit installed (Dometic part number 241 298 500).
|FAILURE||Possible cause||Possible Action|
|The refrigerator does
not cool sufficiently
|• Inadequate ventilation to the unit
• Thermostat setting is too low
• The condenser is heavily frosted
• Too much warm food has been
stored inside within a short period
• The appliance has been running
for a short period of time
• Ambient temperature is to high
|• Check that the ventilation grilles are not
• Set the thermostat to a higher level
• Check that the refrigerator door is
• Allow warm food to cool down before
• Check whether the cooling compartment
works after approx. 4-5 running hours
• Remove winter covers or complete grill
or use fan kit.
|Not cooling on AC||• Is the vehicle connected to site
• Has the RCD tripped in the
• Is the voltage too low on site to
run the fridge (min voltage 195V)
|• Check your site plug and RCD
• Reset the vehicle RCD
• The minimum voltage for the fridge
heating element is 195V (voltage at some
sites can fluctuate)
|Not cooling on DC||• Is the battery charged?
• Is there a blown fuse within the
vehicle control panel?
• Are there any LED’s on the display
(MES OR AES ONLY)
• When the caravan is connected to
the tow vehicle the DC heating
element does not maintain the set
|• Turn on the vehicle battery charger
• Check vehicle fuse box and replace fuses
if required (see vehicle manual)
• The voltage must be above 11.8v for the
MES and AES models to power the PCB.
• Has the customer checked the plug
connection from caravan to car?
|Poor cooling on DC||Poor cooling on DC||The heating element must have a min
voltage of 11.8v to be able to maintain the
fridge temp. Any lower than this heating
element is not able to heat the ammonia
|Not cooling on gas
but cooling on AC
|• Is the fridge gas isolation valve
• Is there gas at the hob?
• Is the Gas cylinder empty?
• Has the fridge been serviced?
(A habitation check doesn’t always
include a fridge gas service)
|• Open valve
• Turn hob on to see if gas is present in
• Change the gas cylinder
• Dometic highly recommended that the
gas parts of the fridge are serviced yearly
depending upon usage. (Please refer to
the operation manual for more
