Capacitor Test: A technician should test the outdoor fan capacitor; if it is bulging or leaking, it requires replacement. Professional Service Recommendation On O General units, you can often find
Since "9C" often relates to internal sensors (Discharge pipe or Expansion valve) or the Inverter PCB, it usually requires a professional to: resistance of the discharge sensor. Electronic Expansion Valve (EEV) for blockages. Inspect the for burnt components.
In many O General inverter models, the 9C code indicates that the system has detected an abnormal resistance value from the compressor discharge pipe thermistor. This sensor is critical because it monitors the temperature of the refrigerant leaving the compressor. If the temperature is too high or the sensor itself fails, the system triggers the 9C code as a safety measure. Common Causes of Error Code 9C
