F-DEFROST HEATER

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.
