MINI SPLIT ERROR CODES

CHUCKSECH
Member Posts: 1
I have a LG mini split air and heat system.
I get error codes on two of the units, (CH 07 AND CH 02)
the 07 code was a short time and went away, the CH 02 code will not go away,
leaving me with a unit that no longer works.
Can someone help.

Here is what I found...
CH02 Fault:
Indoor Pipe Sensor or Outdoor Sensor Assy fault, Open or Short.
Solution:
Disconnect from PCB and measure resistance. Air sensor = 10 kOhm at 25C, Pipe sensor = 5
kOhm at 25C. If not replace sensor.Eugene0
