1
Low voltage. This is shown when the DC supply voltage is low. The battery could be
flat, wiring losses are too high or there is a poor connection to the power source.
2
Fan over-current cut-out. There is a problem with the ventilation fan. It is possible that
the ventilation fan is damaged.
3
Motor start error. The compressor has not started successfully. This can happen in
extreme environments where the refrigerator is heavily loaded & temperature is very high.
4
Minimum speed error. The motor cannot maintain a minimum speed of 1900 rpm.
This can be the result of an Electronic Compressor Driver failure.
5
Thermal cut-out. The electronic circuitry has over-heated. This happens in very hot
environments. This can occur when the fridge is over-loaded with warm contents and
the ambient temperature is high. The electronics will re-set when the temperature
has dropped.
6
Electronic Compressor Driver hardware failure.
