Gree LC fault code

What it means

The inverter cannot bring the compressor up to speed.

Safety: Safe isolation before disconnecting the compressor or testing the inverter board — capacitors hold charge.

UK models this code applies to

LC 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

LC 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.
