Haier LED10 fault code

Haier air conditioning

What the Haier LED10 fault code means, from the manufacturer's own service literature, and the UK models it applies to.

What it means

Defrost temperature sensor failure

The defrost sensor reads open or short circuit.

Safety: Safe isolation before disconnecting sensors or working on the PCB.

How to read it — indoor display + outdoor led1: Faults show as E/F codes on the indoor display; the outdoor PCB reports the same faults as LED1 flash counts — either surface lands you on the same code. (Haier service manual AS25PBAHRA (Pearl), §10 Service Diagnosis)

Now the harder half: proving what caused it

LED10 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.
