How to Fix / Troubleshooting
Warning: This involves high-voltage electronics. Non-professionals should limit actions to external checks.
- 1. Check mains supply: Ensure the supply voltage is within the range specified on the unit rating plate. If not, consult an electrician.
- 2. Inspect power connections: With power off, check that terminal screws at the outdoor unit are tight and that there are no signs of overheating.
- 3. Avoid using long undersized extension cables: The unit should be wired directly with appropriately sized cable.
- 4. If P0 persists with correct supply: The outdoor PCB power section may be faulty and requires professional replacement.
