1-1. General Guidelines
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have
been overheated or damaged by the short circuit. After servicing, see to it that all the protective devices
such as insulation barriers, insulation papers shields are properly installed. After servicing, make the
following leakage current checks to prevent the customer from being exposed to shock hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3) Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive
1-2. Insurance Test
1. Check if there is any leak of current.
2. Cut out the power supply before the repair to avoid an electrical shock hazard.
3. In the case of a live-line test, insulating gloves should be worn to avoid potential electrical shock.
4. Confirm the rated current, voltage and capacity before testing with any kinds of instruments.
5. Watch if the upper door is open when you check something at a lower position.
6. Take out every part in the cabinet before moving the machine, especially things like panels (e.g. glass
shelf).

8. If there is a breakdown with the refrigeration system, please surrender the machine to the service
center, else the leaked refrigerant may pollute the atmosphere .
9. The refrigerator use AC of 115V with a frequency of 60Hz.
10. A big fluctuation of voltage (exceed the range 187～242V) may cause a start failure of the refrigerator, a
burn-out of the control panel and compressor, or an abnormal sound from the compressor in operation.
11. Take care not to damage the supply line. Don't yank at the line; pull the plug out gently from the
