First Thing to Check

Parts Involved

How to Fix

1. 1

   1. Check the motor connector terminal connections and contacts

2. 2

3. 3

   3. Check whether the stator or motor cover is damaged

4. 4

   4. Check for coil disconnections due to foreign material

5. 5

   5. Unplug the motor connector and measure resistance at any two of the three motor terminals — should be 6.0 ohms at 25°C

6. 6

   6. Check if the motor winding coil resistance between Blue-White, White-Red, and Red-Blue is equal to 15 ohms

7. 7

   7. If the PBA control circuit is faulty, replace the PBA
