Gree H7 fault code

What it means

Compressor desynchronising (loss of position)

The drive has lost rotor position — the compressor is not following the commanded speed.

Safety: Safe isolation and capacitor discharge before touching the inverter boards.

UK models this code applies to

From the Gree service literature we hold (Gree (Zhuhai) Service Manual, Bora Inverter R32 §9.1 Error Code List) — not a scraped list.

Now the harder half: proving what caused it

H7 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.
