Possible Causes
Shorted compressor or fan motor, Shorted inverter module, Incorrect breaker size or shared circuit, Damaged power cable
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker; this is a fire hazard.
- Step 1 – Verify dedicated circuit: Ensure the AC is on its own breaker of the correct rating as specified by Gree.
- Step 2 – Inspect power cable: For window/portable units, check the power cord for cuts, burns, or melted areas. Do not use if damaged.
- Step 3 – Isolate cause: If the breaker trips as soon as the outdoor unit tries to start, the compressor or inverter may be shorted.
- Step 4 – Call a technician or electrician: Professional testing of insulation resistance and current draw is required. Components such as the compressor, fan motor, or PCB may need replacement.
