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. |
