Panasonic Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| H11 | Indoor/Outdoor communication abnormal | Verify signal line voltage (should pulse between 0-24V DC). Check interconnecting cable terminal lugs. |
| H16 | Outdoor current transformer (CT) open circuit | Check CT sensor on outdoor PCB, check for low gas charge or compressor lock. Replace outdoor board if CT open. |
| F99 | DC peak detection / compressor overcurrent trip | Megger test compressor windings, verify IPM power module, replace main inverter driver board. |
| F91 | Refrigeration cycle abnormality (Low gas or valve block) | Inspect system operating pressure. Perform dry nitrogen pressure test, seal leak, refill virgin gas by weight. |
