2 The fan does not rotate. - Check whether the fan unit coil is short-
circuited. Measure the resistance and if it
displays infinite level (“0” level is normal) the
coil is short-circuited and the fan unit has to be
replaced.
3 The fan RPM check board (phase control
sensor) is out or defective.
- If the phase control sensor is out, reassemble
it. If the check board is defective, replace the
fan unit.
4 The connection of the connector terminal
is defective.
- Reassemble the connector terminal.
- If the symptoms remain after performing the
above, replace the controller.
