Troubleshooting
4-3-17 Compressor starting/rotation error (Error Code : E461, E467)
1. Check items
1) Check the power and restarting after power reset
2) Check for compressor and compressor wire assembly
3) Check for compressor wire problem
2. Check procedure
Turn off the power and
turn it on again after 30 seconds
Check the power and
restarting after power reset
1. Is there any problem on input power?
(1phase: 220Vac. 3phase: 380Vac)
2. Does error occur again
after resetting the power?
Check the compressor
and wire assembly for the compressor
1. Is resistance value between phases of t
he compressor same? (U ↔ V, U ↔ W, V ↔ W)
2. Is the wire connected to compressor normal?
(disconnection, wrong connection)
3. Is there any noise when the
compressor rotates?
Is the resistance between
compressor body
and chassis MegaΩ?
