| Alarm Code | P29 | |||
|---|---|---|---|---|
| Alarm meaning | Inverter compressor missing phase or lock alarm. | |||
| Alarm conditions | This alarm may occur at start, and occurs when missing phase or lock is detected, and when a DCCT failure occurs. | |||
| Probable cause | Generally this alarm occurs when the refrigerant pressure balance is uneven at start, or when inverter compressor lock occurs, there is a missing phase in the inverter compressor wiring, or a DCCT failure occurs. This can be judged to be starting trouble which is not caused by HIC. | |||
| Check | Check the power wiring and connector wiring. | |||
| Correction | DCCT failure (replace PCB) or compressor failure | |||
| Example | – | |||
| Notes | Use a tester to measure the voltage between the DCCT output terminal on the rear of the PCB and the ground. If the voltage is not within 2 – 3 V, then the DCCT has malfunctioned. | |||
