※1 Ambient temp 25℃
■ Typical Problem
※2 Ambient temp 25℃ to -16℃
※4 Replacement of only the thermistor can not.
※3 Use tester: Digital multimeter
It will be the exchange of the cooling system.
Symptoms
Cause
Test Result
Treatment
Resistance of compressor is ∞Ω
・Normal: Approx. 1.6Ω ※1, ※3
Output voltage of power supply is AC 0V
・Normal: Approx. AC11-18V ※1
Resistance of EVA. thermistor ∞Ω
・Normal: Approx. 2kΩ-10kΩ ※2
Replace of cooling system
Replace fan motor
Charge the bettery
-
Make some room for cool air
Replace the fuse
Replace the fuse
Check the vehicle
■ Technical Data
※1 Ambient temp 25℃
※3 Use tester: Digital multimeter
※2 Ambient temp 25℃ to -16℃
Checking Points
Normal data
Approx. 15kΩ - 5kΩ
Dial position OFF - 5
0Ω
Resistance of EVA. thermistor
Between two pin of the coupler
Approx. 1.6Ω ※1, ※3
Fuse in the vehicle is open
Ventilation at mechanical part is not enough
Checking items
Output voltage of power supply
Input voltage at compressor
Too many things are put inside
Replace the cooling system
Replace the cooling system
※4
EVA. thermisitor is open
Coil of the compressor is open
Compressor does not
work
Power supply is broken
Inside of the fridge does
not get cold
9
Approx. AC 11V - 18V ※1
Between outgoing cords from power supply
Approx. AC 11V - 18V ※1
Socket or other DC power line in the vehicle is bad
Resistance of the compressor
Special Fuse
Fuse at power supply
Approx. 2KΩ - 10KΩ ※2
Between incoming cords to compressor
Power lamp is lit.
Gas is leaking from Cooling Unit
Fan motor is broken
Input voltage is lower than 10V
The special fuse inside DC cord is open
Ambient temparature is higher than 30℃
Cooling is weak
5. TROUBLE SHOOTING
Resistance of the registor variable
Between terminals brown and black.
Current value measurement with clamp meter
between input cord terminals.
Compressor rated current
Approx. 1.7A - 2.0A
Replace power supply
Make at least 150mm room
between unit and wall
Between terminals of compressor
Power lamp is not lit.
