|---|---|---|---|---|
N/A | The refrigerator does not work. | The DC cable's fuse has blown. | Replace the fuse. | DIY Safe |
N/A | The refrigerator does not work. | The vehicle fuse has blown. | Replace the vehicle's fuse - check your vehicle's own manual for the right one. | DIY Safe |
N/A | The refrigerator does not work. | The vehicle battery is discharged. | Check the battery and recharge it. | DIY Safe |
N/A | The refrigerator does not work. | The ignition isn't switched on. | Switch on the ignition. | DIY Safe |
N/A | The refrigerator does not work. | The temperature at the compressor is too low (< 0 °C). | Close/cover all external ventilation grilles completely with insulation material. | DIY Safe |
N/A | The refrigerator does not work. | The refrigerator switches off automatically if the voltage is insufficient. (End-of-discharge voltage: 10.4 V) | Put some load on the battery - the fridge restarts automatically (cut-in voltage: 11.7V). | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor running non-stop. | There's not enough ventilation around the cooling unit. | Check the ventilation grille isn't blocked, and consider moving the fridge somewhere else. | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor running non-stop. | The interior walls have iced up. | Check the door closes properly, confirm the seal fits correctly and isn't damaged, and defrost the fridge. | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor running non-stop. | The temperature's set too high. | Set a lower temperature. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | The ambient temperature's too high. | Take the ventilation grille off for a while so warm air can escape faster. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | Too much food went in at once. | Remove some of the food. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | Too much warm food went in at once. | Take the warm food out and let it cool before putting it back in. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | The refrigerator has not been operating for very long. | Check the temperature again after 4-5 hours. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | The condenser is dirty. | Clean the condenser. | DIY Safe |
N/A | Poor cooling, and the interior temperature's rising. | The fan is defective. | Contact an authorised service agent. | Professional Intervention Required |
N/A | Poor cooling and rising interior temperature, with the compressor barely running. | The battery capacity is exhausted. | Charge the battery. | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor barely running. | There's a break in the connection to the battery electronics. | Establish a connection. | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor barely running. | The main switch (if fitted) has failed. | Replace the main switch. | DIY Safe |
N/A | Poor cooling and rising interior temperature, with the compressor barely running. | The additional supply-line fuse (if fitted) has blown. | Replace the supply line fuse. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (battery-connected). | The battery voltage's too low. | Charge the battery. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (battery-connected). | The battery capacity too low. | Replace the battery. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (battery-connected). | The cables are loose, or the contact's poor (corrosion). | Establish a connection. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (battery-connected). | The cable's cross-section is too small. | Replace the cable. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (battery-connected). | The compressor is defective. | Contact an authorised service agent. | Professional Intervention Required |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (AC-connected). | The connection supply line is interrupted. | Establish a connection. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (AC-connected). | The main switch (if fitted) has failed. | Replace the main switch. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (AC-connected). | The additional supply-line fuse (if fitted) has blown. | Replace the supply line fuse. | DIY Safe |
N/A | Poor cooling and rising interior temperature - the compressor isn't running (AC-connected). | The compressor is defective. | Contact an authorised service agent. | Professional Intervention Required |
N/A | Unusual noises. | Part of the refrigerant circuit can't move freely (it's touching the wall). | Carefully bend the component clear of whatever it's touching. | DIY Safe |
N/A | Unusual noises. | Something has got wedged behind the cooling unit. | Remove the foreign object. | DIY Safe |
N/A | Unusual noises. | Fan noise. | Contact an authorised service agent. | Professional Intervention Required |
N/A | The drawer opens on its own while moving (e.g. driving). | The door latch isn't positioned correctly. | Adjust the door latch position. | DIY Safe |
N/A | The drawer does not close properly. | The door latch isn't positioned correctly. | Adjust the door latch position. | DIY Safe |
N/A | The drawer does not close properly. | The door latch's been adjusted, but the drawer still isn't latching properly. | Ensure that the drawer is properly latched and secured when closing. | DIY Safe |
2 flashes | Error indicator LED flashing orange | The fan's drawing more than 1A (excessive fan current). | Check fan and wiring. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
3 flashes | Error indicator LED flashing orange | Either the rotor's jammed, or the cooling system's pressure differential is too high (motor won't start). | Check for obstructions around the compressor. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
4 flashes | Error indicator LED flashing orange | The cooling system's overloaded, so the motor can't maintain its minimum speed (speed too low). | Reduce load and ensure adequate ventilation. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
5 flashes | Error indicator LED flashing orange | A heavily loaded cooling system, or too high a temperature setting, can overheat the electronics. | Improve ventilation and reduce ambient temperature. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
Constantly | Error indicator LED flashing orange | Temperature sensor is defective (Temperature sensor errors). | Contact an authorised service agent. | Professional Intervention Required |
