Error Code LE
Locked Motor Error - Motor rotor locked or motor drive fault
Moderate
Address soon - your appliance may not work properly
Also displayed as: LE
What This Means
Motor drive connector (YL3 or BL6) disconnected; Rotor magnet cracked or damaged; Stator winding resistance out of spec (should be 5-15 Ohm phase-to-phase); IPM (Intelligent Power Module) shorted on Main PCB
How to Fix
- 1
Check motor drive connector on Main PCB Assembly (YL3) and the wire-side motor connector. If disconnected, reconnect the connector/wire/motor.
- 2
Remove the rotor and inspect rotor magnet for cracks. If cracked, replace the rotor.
- 3
Disconnect the YL3 connector and measure stator winding resistance phase-to-phase: U-V, V-W, W-V. Each should read 5-15 Ohm (U=1, V=2, W=3 per connector pin mapping). If out of range, replace the stator.
- 4
If winding resistance is in spec, check the IPM on the Main PCB controller for a short circuit. If IPM is shorted, replace the Main PCB Assembly.
