Gree H6 fault code

Gree air conditioning

What the Gree H6 fault code means, from the manufacturer's own service literature, and the UK models it applies to.

What it means

No feedback from the indoor fan motor

The indoor DC fan motor gives no speed feedback — the unit stops to protect itself.

Safety: Isolate before working near the fan — it can restart without warning.

Tap yours to open H6 on that machine.

H6 on these comes from each model's own manual, which may not match the meaning above — tap yours to read it.

Now the harder half: proving what caused it

H6 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
