    MINI SPLIT ERROR CODES

    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.
