10-2-5. Diagnostic Procedure for Each Check Code (Outdoor Unit)<br />
<br />
1) This section describes the diagnostic method for each check code displayed on the remote controller.<br />
2) In some cases, a check code indicates multiple symptoms.<br />
In this case, confirm LED display on the outdoor P.C. board to narrow the contents to be confirmed.<br />
3) The check code on the remote controller is displayed only when the same error occurred continuously by<br />
multiple times while LED of the outdoor P.C. board displays even an error which occurred once.<br />
Therefore the display on the remote controller may differ from that of LED.<br />
