ERROR CODE CH5 AIRCON SPLIT LG


This error is a communication error between your indoor and outdoor unit. You can try turning the breaker off for a few minutes and restart the unit. However if that does not work its best suggested to have an authorized HVAC technician service the unit.

Try to unplug the unit or “off” after 10sec. “on” the circuit breaker and then start the unit.
But if the defect persist then you need a qualified technician. The below error may be the cause of unit failure.
- Out of range thermistor is also can also be the cause of tripping outdoor unit with matching blinking light same as low refrigerant.
- Dirty indoor and outdoor can also be the cause
Remote control units have diagnostic program in the
control, after 3 to 5 minutes of operating if the diagnostic
tools detect abnormal operation, then its shutdown the unit
to protect from damage. Thermistor sensor is one of the
parts that detect the operation of the unit. Out of range
or defective thermistor can shut the operation of the unit.
- If your indoor and outdoor is clean start the unit in cool mode and monitor the outdoor pipes. If your suction pipe is icing or dry then your unit is under charge, but if your suction is cold and sweating then the system is ok and sure that the thermistor sensor is defective.
- Out of range thermistor sensor in both return air and freeze up sensor can cause the tripping “off “ the unit. The resistance of both thermistor is 8 to 10k ohms, so can test by using ohm meter
