Questions people ask

My LG AC has no display. How do I read the code?

Count the LED blinks. LG says the first LED shows the first digit and the second LED shows the tens digit. Five blinks on the first LED means CH05.

Is CH00 a serious fault?

Often not. LG describes it as a code that can come from a temporary electrical cause. It needs service only if it keeps coming back.
