POWER CUTTING IN/OUT
• The 50L and 65L fridges both have an inbuilt voltage meter on the main screen that shows
the current voltage, however the 75L does not. Use the voltage meter to help troubleshoot
circuit and battery faults.
• Your fridge has built in battery protection and needs a minimum 10.9V to start and 9.6V to
continue operating.
• During operation a load is placed on the circuit and power supply and the voltage can drop
by as much as 2V, many things can affect voltage drop, such as: increased resistance from
long cables, or cables that are undersized or oversized for the application. Poor or loose
connections can also increase resistance.
For example: The fridge turns on runs for 1 minute then turns off. The likely problem is that
the battery and wiring circuit have sufcient voltage to start but when a load is applied (the
compressor starting) the voltage will drop below 9.6 and the fridge turns off. This cycle will
repeat as the load is removed from the battery the voltage will begin to show 10.6 which is
enough to start the cycle again. Try to test fridge with 2 separate batteries before raising a
warranty claim.
NOTE: If the fridge is able to run on the AC/DC transformer the problem is likely a faulty
battery, wiring or connection.
COMMON 12V POWER SUPPLY ISSUES
Wiring
The standard wiring from the car battery to the 12V outlet may not be rated to power the fridge.
Ensure the wire gauge is of sufcient size to supply the fridge’s current draw over the length
required. If unsure, check with the vehicles instruction manual or, contact a local automotive
electrician for advice.
NOTE: Always fuse wiring with an in-line 15A fuse as close as reasonable possible to the power
source (i.e. the battery).
Battery
The car battery could be old, undersized or have a dead cell causing too much voltage drop. If the
battery contains a dead cell it may still show that it has voltage with no load applied. When a load
is applied the cell will drop and subsequently so will the voltage.
Connections
The 12V plug, car 12V socket or any of the connections between the fridge and the battery could
be faulty or have come loose since installation.
6. TROUBLESHOOTING
CODE DESCRIPTION ACTION
E1 Battery Voltage is low. Check battery voltage and adjust Low
Voltage Cut-Off as required.
E2 Fan failure / Frequent start-stop. Contact point of sale to arrange further
action.
E3 Compressor startup problems.
Check air vents are clear.
Move fridge to cooler location (ambient
temperature may be too high).
E4 Compressor’s running speed fails to
reach the requirements.
E5 The model is overloading.
E6 NTC failure (open circuit or short circuit)
