TROUBLESHOOTING
1) At the normal operation, press the Power Cool or F Power Freezer or Temp + Power Freezer buttons for 6
seconds. Then, the entire Display Panel blinks at intervals of 0.5 second for 4 seconds.
2) At this time, release the Power Cool or F Power Freezer or Temp + Power Freezer buttons and press the
Alarm button. Then, with “Ding Dong” sound, it goes into the Load Display mode.
3) The Load Display function shows what MICOM signals come out from MAIN PCB.
But, it just indicates that there are MICOM signals coming out. It does not necessarily mean that the related parts (Loads)
are operating. In other word, even though it shows a certain load working, the related part may not operate due to such as
a defective PCB relay or the defective part itself. Also, this function can be used in trouble-shooting.
4) The Load Display function lasts for 30 seconds and then it goes back to the normal operation.
