Possible Causes
Tripped breaker or blown fuse, Loose power wiring at indoor terminal block, Faulty indoor power supply board, Defective main PCB
How to Fix / Troubleshooting
Safety first: Always turn OFF the main breaker before removing covers. Use a non‑contact voltage tester if available.
- Step 1 – Check breaker and fuses: Locate the dedicated AC breaker and ensure it is ON. Reset if tripped. Check any external fuses near the outdoor unit.
- Step 2 – Verify outlet or supply: For window or portable Gree units, test the wall outlet with another appliance.
- Step 3 – Inspect indoor wiring: With power OFF, remove the indoor front cover and check that the power wires are firmly secured in the terminal block and that there are no burnt marks.
- Step 4 – Look for PCB damage: If accessible, inspect the indoor PCB for burnt components or bulging capacitors.
- Step 5 – Technician service: If power supply is confirmed but the unit remains dead, the indoor power supply board or main PCB likely needs replacement.
