PRELIMINARY ACTIONS
1. Switch off the Daikin unit via the user interface.
2. Switch off the Daikin unit with the field supplied circuit breaker.
3. Remove plate work when required (refer to "Basic removal" on page 68).
PROCEDURE
1. Check the state of the propeller, replace the propeller if damaged, deformed, cracked or broken (refer to "Replacing propeller
fan blade assembly" on page 85).
2. Check the motor shaft bearing friction, only perform electrical check if motor runs with low shaft bearing friction. Replace fan
motor if friction is abnormal (refer to "Replacing DC fan motor assembly" on page 79).
PRELIMINARY ACTIONS
1. Switch off the Daikin unit via the user interface.
2. Switch off the Daikin unit with the field supplied circuit breaker.
3. Remove plate work when required (refer to "Basic removal" on page 68).
PROCEDURE
1. Check fuse on PCB, replace if blown, see table "Component checklist" on page 111.
2. Check if fan motor connector is plugged into PCB.
3. Power the Daikin unit.
4. Check power supply, the measured voltage must be 198 - 240 VAC, if not replace main PCB (refer to
"Replacing main PCB"
on page 84
).
Technical specification Description
The motor has a single connector for DC power and the rotation
counter feed back from the integrated pulse generator
