Indoor Unit: Inverter Compressor Motor Lock
Remote Control
Display
E5
Subcode 6
Applicable Models
All indoor units
Method of
Malfunction
Detection
Inverter PC board takes the position signal from UVW line connected between the inverter and
compressor, and the malfunction is detected when any abnormality is observed in the phase-current
waveform.
Malfunction
Decision Conditions
This malfunction will be output when the inverter compressor motor does not start up even in forced
startup mode.
Supposed Causes
Compressor lock (liquid suction (oil shortage))
High differential pressure (0.5MPa or more)
Incorrect UVW wiring
Faulty inverter PC board
Stop valve is left in closed.
Troubleshooting
Warning
: CAPACITOR SHOCK HAZARD. The capacitors (top surfaces) can hold up to 220V. Use
correct precautions when servicing.
Check the installation conditions.
Is
the stop valve
open?
NO
Is the UVW wiring
normal?
NO
NO
NO
NO
Is high
differential pressure
starting? (0.5MPa or
more)
YES
YES
YES
Check
and see whether
compressor is short-circuited
or ground.
YES
YES
Are inverter
output voltages the same
for 3 phases?
Does low
or high pressure
vary even instantaneously
when restarting
compressor?
YES
Caution
Be sure to turn off power switch before connecting or disconnecting
connector, otherwise parts may be damaged.
Open the stop valve.
Connect correctly.
Remedy the cause.
Replace the compressor.
Replace the inverter PC
board Assy.
Replace the compressor.
