Reference for circuit diagnostics 12-3) Check a load 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.
