Method of
Malfunction
Detection
Malfunction is detected according to the voltage waveform of main circuit capacitor built in
inverter.
Malfunction
Decision
Conditions
When the aforementioned voltage waveform becomes identical with the waveform of the power
supply open phase.
Supposed
Causes
Open phase
Voltage imbalance between phases
Faulty outdoor inverter PC board
•
Faulty main circuit capacitor
•
Power unit (Disconnection in diode module)
•
Faulty Magnetic Relay (K11R, K12R)
•
Improper main circuit wiring
Troubleshooting
Check
LED on the
outdoor unit PC board
(Open phase?)
Open
phase of power supply
voltage?
Is the voltage
imbalance between phases
large?
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
Replace the outdoor PC board
(A2P).
