5. How to check the F an-E rror

(1) ~ J uly 2007

After  sending  a  signal  to  the  fan,  the  MIC OM  checks  the  B LDC   fan  motor’s  lock  status.  If  there  is  no
feedback  signal  from  the  B LDC   fan,  the  fan  motor  stops  for  10  seconds  and  then  is  powered  again  for  15
seconds.  To  determine  that  there  is  a  fan  motor  malfunction,  this  process  is  repeated  5  times.  If  the  fan
motor is determined to be defective, the error code will be shown continuously in the display.
At this point, there is no further check of the fan motor.

After  sending  a  signal  to  the  fan,  the  MIC OM  checks  the  B LDC   fan  motor’s  lock  status.  If  there  is  no
feedback  signal  from  the  B LDC   fan,  the  fan  motor  stops  for  10  seconds  and  then  is  powered  again  for  15
seconds.  To  determine  that  there  is  a  fan  motor  malfunction,  this  process  is  repeated  3  times.  If  the  fan
motor is determined to be defective, the error code will be shown in the display for 30 minutes.
At  this  point,  the  process  will  be  repeated  until  the  fan  motor  operates  normally.  If  normal  operation  is
achieved, the error display is erased and the MIC OM is reset automatically.
