LG Therma V fault CH45
Condenser mid pipe sensor open/short
Heat pumpWhat it means
Open / short of outdoor unit condenser mid pipe sensor
Likely causes
- Check the sensor stewed condition
- Check for sensor burnout
Where to start
- Is the sensor properly inserted in the PCB? If No, insert it properly into the PCB (reassemble the sensor).
- Is the sensor normal? If No, replace sensor.
- Is the sensor assembly in good condition? If No, replace sensor.

Safety: Isolate the outdoor unit and any backup heater, and give the inverter capacitors time to discharge before you open the electrics. Anything on the refrigerant circuit needs F-gas certification.
From the LG manual for the Therma V. Check the model on the data plate before you order parts.
