Gree H5 fault code

What it means

IPM module current protection

The inverter power module has tripped on current. Genuine module faults and a mechanically struggling compressor look the same to the drive, so separate them before ordering a board.

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

H5 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.
