4. DIAGNOSIS METHOD OF FAILURE AROUND PWB
In case of any abnormality of refrigerator, check by the following procedure;
1. Disconnect power supply and check the following point.
• Is there any failure portion in inserting connectors?
2. Detach the PWB and check the appearance.
• Is there any burning or abnormal damage?
3. Check the conditions of the fuse and the varistor. (Fuse and varistor are located at the position in the figure.)
• Under the condition of power supply plug connected;
When the fuse F1 or F2 or F3 (SJ-WS320T/RP320T) / F1 or F2 (SJ-WP320T/RM320T/WM322T) is melt down,
PWB does not operate at all. (No cooling and no indoor lamp)
When the fuse F4 (SJ-WS320T/RP320T) / F3 (SJ-WP320T/RM320T/WM322T) is melt down, only defrosting
heater is not electrified. (It will be diagnosed as “Defrosting failure” by the self diagnosis.)
• Melting in the fuse cannot be checked visually (as the safer one than transparent glass tube is used). Be sure to
detach the connector “CN1” before measuring the resistance between the both ends of the fuse by the tester.
• Next, check the visible damage of the varistor.
