1. Fan mo<strong>to</strong>r defect / assembly condition<br />
abnormal<br />
2. Wrong connection of fan mo<strong>to</strong>r connec<strong>to</strong>r<br />
(Hall sensor, U,V,W output)<br />
3. Reversing rotation after RPM target apply<br />
4. Fan PCB assembly defect<br />
Check ODU Fan Mo<strong>to</strong>r assemble condition and fan locking<br />
→ Reassemble or replace if abnormality found<br />
1. Check resistance between each phase(U,V,W) of ODU<br />
fan mo<strong>to</strong>r terminal (16.8Ω ±5% at 75°…)<br />
2. Check insulation resistance between ODU fan mo<strong>to</strong>r<br />
terminal(U,V,W)<br />
→ Replace fan mo<strong>to</strong>r if abnormality found<br />
Check wiring between OUD fan mo<strong>to</strong>r and fan PCB<br />
( Check if Hall Senor and Mo<strong>to</strong>r output terminal color is<br />
matched)<br />
→ Reassemble if abnormality found<br />
Replace Fan PCB assembly<br />
