SiUS331708EA
219
Service Diagnosis
4.46 Inverter Circuit Capacitor High Voltage
Error Code
P1
Applicable
Models
All outdoor units
Method of Error
Detection
The voltage waveform of the main circuit capacitor of the inverter is used to check for errors.
Error Decision
Conditions
The above-mentioned voltage waveform looks like the waveform of the power supply with a
missing phase
Supposed
Causes
Defective main circuit capacitor
Incorrect main circuit wiring
Defective outdoor unit PCB
Unbalanced voltage between phases
Missing phase
Troubleshooting
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
NO
NO
YES
YES
Measure voltage between L1 and L2,
L1 and L3, and L2 and L3.
Is three-phase power
voltage within rated voltage
±10%?
Is the
unbalanced phasic voltage
within ±10%?
Calibrate the power voltage.
Calibrate the power voltage.
Replace the outdoor main
PCB (A1P).
