Unplug the powercord and disconnect the
main PCB CN70 and CN71, the measure the
follows :
1. As shown in table below, measure the
resistance between terminals, check load
trouble and wire connection error.
2. The diagram of circuit was drawn based on the
maximum load. When a repair is needed, see
the electric wiring diagram on the back of
refrigerator to troubleshoot the corresponding
model.
3. For safety, you must turn the power off.
