What does “Err2” mean on my ARB 78L's display?
If your ARB Refrigerator's digital display shows “Err2”, the thermistor circuit is ‘short circuit”. Test the thermistor and replace it if necessary.
What does “Err1” mean on my ARB 78L's display?
If your ARB Refrigerator's digital display shows “Err1”, the thermistor is not correctly connected to the control panel circuit board; check its connection. Alternatively, the thermistor circuit may be ‘open circuit’; test the thermistor and replace it if necessary.
Why does the lid of my ARB 78L Refrigerator open while driving?
If your ARB Refrigerator's lid opens during transit, first, ensure that the latch was correctly closed before transportation. If the issue persists, inspect the latch and latch pivot for damage, and replace the latch assembly if necessary, as the latch may be faulty.
Why is the latch on my ARB Refrigerator hard to disengage?
If the latch on your ARB Refrigerator does not easily disengage from the lid, it could be due to the high-quality seal causing the lid to sit away from the fridge cabinet; press down slightly on the lid to help disengage the latch. Alternatively, the latch itself may be faulty; inspect the latch and latch pivot for damage, and replace the latch assembly if necessary.
Why is my ARB 78L not reaching the set temperature?
If your ARB Refrigerator does not reach the target temperature, it might be operating at its maximum cooling capacity in extreme ambient temperatures. The maximum cooling capability of the system is a reduction of 50°C (122°F) below the ambient temperature.
What to do if my ARB 78L runs but does not cool?
If your ARB Refrigerator does not cool but the compressor runs, ensure there is sufficient clearance around the fridge and that the fan is not obstructed to provide proper ventilation. Check that the correct battery protection setting is selected. Inspect the lid seal for damage or if it's missing, and replace it if necessary. Also, look for any visible oil leaks around the refrigeration lines, compressor, and condenser. If you detect a leak or suspect a blockage within the refrigeration system, contact a qualified refrigeration mechanic for assistance.
Why does my ARB 78L have an intermittent power supply?
If you are experiencing intermittent power supply to your ARB Refrigerator, it could be due to a poor connection of the plug into the socket at the back of the fridge, or a poor connection of the plug into the supply socket. Check that both plugs are correctly installed. It's also possible that the compressor has stopped running because the battery cut-out voltage has been reached. Ensure the correct battery protection setting is selected and that the vehicle wiring is adequate.
Why won't my ARB 78L run when the voltage is above 13.8V?
If your ARB Refrigerator will not run when the DC input voltage exceeds 13.8V, the main circuit board may be faulty. Replace the main circuit board and retest to resolve the issue.
What does it mean when the error light flashes twice on my ARB Refrigerator?
If your ARB Refrigerator does not run, and the error light flashes twice every 5 seconds, it could be due to a few reasons. The fan might not be correctly connected to the compressor control unit, so check the fan wiring to ensure the "+ve" and "–ve" fan wires are properly connected. Alternatively, the fan itself could be faulty, in which case you should test and replace it if necessary. Lastly, the compressor control unit might be faulty, requiring testing and potential replacement.
Why does the device fuse in my ARB 78L Refrigerator keep blowing?
If your ARB Refrigerator's device fuse repeatedly blows, it could be due to a short circuit in the 100-240V AC fridge cable. Check the cable's continuity and replace it if it's faulty or damaged. Another cause could be a short circuit between the "L" and "N" terminals on the compressor control unit; check for this. Lastly, an unregulated or fluctuating power supply, such as from an engine-driven generator, might be the issue. Ensure the generator has a voltage regulator and supplies a standard, pure sine wave AC voltage without fluctuations.
