Possible Causes
Compressor drawing excessive current due to mechanical failure, Shorted compressor windings, Power supply issues (low voltage, loose connections), Faulty inverter power module (IPM) on outdoor PCB
How to Fix / Troubleshooting
Safety first: Switch OFF the breaker and do not repeatedly restart the unit—this can damage the compressor and electronics. Electrical diagnostics inside the outdoor unit should only be done by qualified personnel.
- Step 1 – Check supply voltage (basic): If you have a plug‑in voltage monitor, verify that line voltage is within the range specified on the Gree nameplate. If voltage is unstable, contact an electrician or utility provider.
- Step 2 – Inspect wiring connections (visual only): With power OFF, remove the outdoor electrical cover and look for burnt wires, loose terminals, or melted insulation. Do not touch capacitors or live parts.
- Step 3 – Power reset: Restore power after 10 minutes and try a single restart. If E5 appears again, stop using the unit.
- Step 4 – Call a technician: A professional should measure compressor current, test compressor windings, and check the outdoor inverter PCB (IPM module). They may need to replace the outdoor main PCB or compressor.
