Hello. The problem is following: LG channel air conditioner AB-H1208VAO (B120AH SVO) (Freon 410). After a while of operating it displays an error (CH 33). I came across it for the first time, I thought there were only 4 of them. Thanks beforehand.

Answer: The error presupposes the exceeding of a temperature of compressor discharge with a permanent drive. (Compressor overheating)
