Possible Causes
Low or high supply voltage, Faulty PFC circuit on inverter board, Loose power wiring, Defective DC bus capacitors
How to Fix / Troubleshooting
Safety: High DC voltages present. Do not touch components on the inverter board.
Steps:
- Check supply voltage: Measure line voltage at the outdoor unit. If outside the specified range, correct the supply issue (contact an electrician if needed).
- Inspect terminals: With power off, tighten all power terminals and look for signs of overheating.
- Surge protection: Consider installing a surge protector or voltage stabilizer if your area has unstable power.
If P0 persists with correct supply voltage, the outdoor inverter PCB likely needs replacement by a technician.
