How to fix Gree E5
Wait for stable power
If the power has been flickering, turn the system off and wait for things to settle.
Spot a pattern
After a reset, note when E5 comes back, for example only on the hottest afternoons or when another big appliance kicks on.
Clean filters and the outdoor coil
Shut off the outdoor disconnect, clear the outdoor coil, and rinse the indoor filters. Less strain on the system means less current draw.
When to call a technician
Repeated E5 needs a technician or electrician to check the supply voltage and wiring. GREE says the electrical supply has to be inspected and stabilized.
