Compressor coil is open circuit Compressor coil resistance is ∞Ω Replace the cooling unit
No cooling ( Normal: 1.23Ω ※1 )
Power Supply brake down Power Supply output voltage is AC 0V Replace the Power Supply
Control Compressor does not ( Normal: AC14〜18V )
indicating lamp operate. Wire thermistor is open circuit Thermistor resistance is ∞Ω Replace the thermistor
is lighting ( Normal: 2kΩ〜10kΩ )
* Cooling Unit gas leak Replace the cooling unit
* Fan motor brake down Replace the fan motor
Cooling performance is * Input voltage is lower than DC 10V Charge the battery
not enough. * Ambient temperature is higher than 30℃
* Ventilation for compressor and condenser is not At least make clearance
enough
100 mm between fridge and wall
* To be stored too much in the fridge Make good circulation of cold air
* The special fuse of the DC cord blow out Replace the fuse
Control indicating lamp is not light * Fuse of the vehicle blow out Replace the fuse
* DC power line of the vehicle is not good Check the vehicle
