Gree H5 fault code

Gree air conditioning

What the Gree H5 fault code means, from the manufacturer's own service literature, and the UK models it applies to.

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.

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.
