Dear all,

We have one Lg Vrv sistem with wired remote controllers.
We have found error CH69 blinking on remote controller.

We try to investigate all available service manuals and we cant find any explanation of this error.

I try to open outdoor unit,and found everything in order,no connection failures,refrigerant is ok,no shorted or opened sensors.

After that without any reason,error message cleared by itself and unit works perfectly.
But unfortunately,the same error message appears from time to time.

Maybe somebody have experience with this problem?

Thank you very much.

Are you sure that it is CH69?
From the error code list that one doesn't exist

Sandy,
from my trouble shooting guide book, CH69 denotes constant speed compressor CT (current transformer) is defective (not plugged in, wire broken, bad connection etc). CH69 may be displayed on the remote controller but if you can catch it on the outdoor unit it will be CH691 for the master outdoor unit, CH692 for master 2 outdoor unit, CH693 for slave 3 & so on.

Good luck on finding the sneaky critter!
