Possible Causes:
Power not connected or insufficient voltage
Incorrect temperature setting
Poor ventilation around the unit
Compressor not running
Solutions:
Ensure both 12/24 V DC or 220 V AC power sources are correctly plugged in.
Check that voltage is above 10.5 V (12 V mode) or 22 V (24 V mode).
Adjust the temperature to the desired setting using the control panel or remote.
Maintain at least 150 mm clearance for airflow around the vents.
Confirm that the compressor operates once powered.
Possible Causes:
Faulty power cable or loose plug connection
Incorrect power source selected (AC / DC)
Fuse blown
Solutions:
Inspect and reconnect all power leads.
Verify the correct input mode is selected.
Check and replace the fuse if blown (refer to fuse rating in the manual).
Possible Causes:
Low-voltage protection activated
Ambient temperature too high
Poor ventilation causing compressor overload
Solutions:
Adjust the low-voltage cut-out to a lower setting (10 V or 10.7 V).
Allow the fridge to cool in a shaded, ventilated area.
Clean condenser vents and ensure airflow around the cabinet.
Possible Causes:
Lid not sealed properly
Frequent opening of the lid
High ambient humidity
Solutions:
Check the lid gasket for proper sealing.
Limit unnecessary lid openings.
Defrost the unit when frost thickness exceeds 5 mm.
Possible Causes:
Temperature sensor fault or disconnection
Poor internal air circulation due to over-packing
Solutions:
Inspect the temperature sensor connection and wiring.
Rearrange stored items to improve air circulation.
Restart the unit after inspection to reset the system.
