Also displayed as: AE

How to Fix

1. 1

   Check all compressor wiring connectors at main PCB — verify connectors are fully seated and not damaged

2. 2

   Measure inverter compressor winding resistance at 25°C: terminal C-R should be 2.56 Ω ±0.30 (blue & red); terminal C-S should be 2.56 Ω ±0.30 (red & black); third pair (black & blue) should be 2.56 Ω ±0.30

3. 3

   Replace wire harness if damaged (R code: A190)

4. 4

   Replace main PCB (R code: A160)

5. 5

   If issue persists, replace base assembly including compressor (R code: C600)
