One Flash

• Insufficient cable size
• Too many connections
• Poor connections
• Not designating fridge
with own direct circuit from battery

Battery Protection Cut-Out

If the error light on your fridge flashes once every 5 seconds, it is definitely indicating that you have a voltage drop problem.
This means that the wiring in your car may be inadequate to carry the correct amount of volts to the fridge.
To test if this is the problem, plug the fridge into a suitable AC adaptor. If you find that the fridge works, you can eliminate that there is a problem with the fridge and the car wiring configuration or plug connections should be stringently checked.
Recommended supply wiring 6-8 sq mm for up to 4 metres, to avoid excess voltage drops. Above this length, +1mm for every metre.


Two Flashes
Fan over current cut-out
If the fan circuit in the control module has a load in excess of 0.5 Amps, the system will fail.

Three Flashes
Motor Start Error
If your error light is flashing three times every 5 seconds, the rotor may be blocked or the differential pressure in the refrigeration system is too high. Faulty compressor or faulty control module.

Four Flashes
Minimum Motor Speed Error
This failure occurs if the compressor is running slower than 1850 rpm.

Five Flashes
Thermal cut-out of electronic unit
If the error light is flashing five times every 5 seconds, the refrigeration system has been too heavily loaded, or if the surrounding temperature is high, the electronics will run too hot. This is generally caused by not allowing enough ventilation around the vents of your fridge. To overcome this, simply ventilate your fridge more effectively.
