Troubleshooting and error codes
| No | Procedure | Inspection Method | Cause |
|---|---|---|---|
| 1 | Plug out and pull the PCB out of the control box Check the PCB fuse |
1) Is 1st fuse disconnected? 2) Is 2nd fuse disconnected? |
. Over current . Indoor Fan motor short . AC part and pattern short of Indoor PBA |
| 2 | Supply power If the operating lamp twinkles at this time, the above 1) ~ 3) have no relation |
Check the power voltage 1) Is the BD71 input voltage 200Vac~240Vac? 2) Is the voltage between both terminal of IC02 pin #1-#2 12Vdc? 3) Is the voltage between both terminal of IC02 pin #2-#3 5Vdc? |
