What does Gree error E6 mean?
E6 means the indoor unit cannot talk to the outdoor unit. There is a problem in the wire joining them or in one of the boards, so the compressor won't run and only the indoor fan works.
Why does code E6 appear?
- The wire between indoor and outdoor units is loose, cut or wrongly connected.
- Mains voltage is very low.
- The indoor or outdoor board is faulty.
- Rats or rain have damaged the wire.
What can you safely check for E6?
- Switch the power off for 5 minutes, then start the AC again.
- Look from outside for a cut or burnt wire. Don't touch the wires.
- If the voltage is low, wait until it is normal.
Safety: never reach into an electrical panel, board, gas pipe or the inside of an inverter yourself. You can get a shock or release gas. This is a mistri's job.
When should you call a mistri?
If E6 stays after a reset, call a mistri. Opening wire connections and checking boards is electrical work; don't do it yourself.
