9-4 How to check Fan-Error
(1) After sending a signal to a fan, MICOM checks BLDC fan motor s lock status.
If there is no feedback signal from BLDC fan,
fan motor stops for 10 seconds and then operate for 15 seconds.
To determine there is a fan motor malfunction, this process is repeated 3 times.
If the fan motor is determined to be defective, an 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 disappears and
the MICOM is resets automatically.
