Why does the compressor on my ARB 78L run constantly?
- M
  Matthew HernandezSep 2, 2025
  If your ARB Refrigerator is running, but the compressor runs continuously, first, check for poor ventilation by ensuring there is sufficient clearance around the fridge and that the fan is not obstructed. Also, consider if the fridge is operating near its thermal capacity. Inspect the lid seal for damage or if it's missing, and replace it if necessary. A faulty thermistor, control panel circuit board, or main circuit board could also be the cause, requiring testing and potential replacement. Finally, an insufficient charge of refrigerant or a partial blockage within the refrigeration system may be the issue, in which case you should contact a qualified refrigeration mechanic.

What to do if I can't change the temperature on my ARB Refrigerator?
- R
  Ronald FloresSep 1, 2025
  If your ARB Refrigerator runs but you cannot change the target temperature, the control panel circuit board may be faulty. To resolve this, test the fridge with a new control panel circuit board, and replace it if the issue is resolved.

Why is my ARB 78L Refrigerator not powering on with AC power?
- A
  Angela HollowayAug 31, 2025
  If your ARB Refrigerator is not getting power from a 100-240V AC power supply, check that the plug is correctly installed into the socket at the back of the fridge. If that’s not the problem, the device fuse in the back of the fridge cabinet may have blown and needs replacing. Also, ensure that there is power to the supply socket from the AC power source. Check for poor electrical connections inside the fridge between the AC power socket and the compressor control unit, and test the main circuit board and compressor control unit, replacing them if necessary.

Why does the fuse keep blowing in my ARB Refrigerator's DC power lead?

  Jamie ChaneyAug 30, 2025
  If the 12/24V DC fridge lead plug fuse blows repeatedly on your ARB Refrigerator, the issue could be a fault within the 12/24V DC fridge power lead itself. Check the lead's continuity and replace it if it's faulty or damaged. Alternatively, the incorrect fuse might be in use; ensure you install the correctly rated fuse (T8 Amp 32V). A short circuit between the "+" and "-" terminals on the compressor control unit could also be the cause; check for any such short circuits.

Why won't my ARB 78L run on DC power, but the light is on?
- M
  Mrs. April ObrienAug 29, 2025
  If your ARB Refrigerator does not run when using a 12/24V DC power supply, but the interior light works, it could be due to several reasons. If the power LED is orange, the fridge has reached the set temperature; try reducing the target temperature. If that's not the case, there could be a faulty compressor control unit, control panel circuit board, main circuit board, or thermistor. These components need testing, and possibly replacing. A fault within the main wiring loom or a faulty compressor could also be the cause. If the compressor is faulty, contact a licensed refrigeration mechanic.

How to fix a digital display that is not visible on ARB Refrigerator?
- A
  Amanda RussellAug 28, 2025
  If your ARB Refrigerator is running, but the digital display is not visible, the control panel circuit board may be faulty. To resolve this, test the fridge with a new control panel circuit board, and replace it if the issue is resolved.

Why does the compressor stop and the error light flash on my ARB 78L?
- E
  Emily YoungAug 27, 2025
  If your ARB Refrigerator's compressor stops, the LED display is visible, and the error light flashes once every 5 seconds, it means the compressor stopped because the battery cut-out voltage was reached. To solve this, verify the correct battery protection setting is selected. Also, ensure the vehicle wiring is adequate. Check the battery voltage and the voltage at the supply socket, and make sure the plug is correctly installed into the socket at the back of the fridge and into the vehicle's supply socket. You can also test the fridge on 100-240V AC to confirm it's operating correctly.

What to do if my ARB 78L Refrigerator has no power with 12/24V DC and the light doesn't work?
- L

  If your ARB Refrigerator is not getting power from a 12/24V DC supply and the interior light isn't working, there could be several reasons. It could be a blown interior light globe, a blown 12/24V DC plug fuse (which should be replaced with a T8 Amp 32V fuse), a fault with the 12/24V DC fridge power lead (check and replace if necessary), a poor connection of the plug to the socket, no power to the supply socket, the DC supply voltage being too low, incorrect polarity of the fridge power circuit, or a poor electrical connection inside the fridge. Check each of these to resolve the issue.

Why is the lid of my ARB 78L Refrigerator hard to open?
- S
  Shannon VaughnAug 26, 2025
  If the lid of your ARB Refrigerator is hard to release from the body, the hinge assembly may have become contaminated with dirt. Carefully remove the lid, clean any dirt or grit from the hinge sockets, and service the hinge assembly.

Why is the interior light not working in my ARB Refrigerator?
- M
  Maxwell WilliamsAug 25, 2025
  If your ARB Refrigerator's interior cabinet light does not work, it could be due to several reasons. The interior light globe may have blown, so replace it. There might be no power to the fridge, so ensure that either 12/24V DC or 100-240V AC power is being supplied. A faulty main circuit board or light switch could also be the cause, requiring testing and potential replacement of the circuit board or cabinet assembly.
