1. Inverter comp. discharge temp.
sensor defect
2. Refrigerant shortage / leakage
3. Defective LEV
4. Defective Liquid Injection Valve
5. Defective Hot Gas Bypass Valve
■ Defect inspection method :
1) In case there is no actual rise of the discharge temp of the inverter comp.(A) but the sensor shows abnormal
rise of the temp, then please replace the discharge pipe sensor
- Discharge temp sensor 10°C=362kΩ,25°C = 200kΩ,
50°C = 82kΩ, 100°C=18.5kΩ
In case there is no actual rise of the discharge temp of the inverter comp.(A),
then please replace the outdoor MAIN PCB.
2) Check the indoor / outdoor LEV / Hot gas / Liquid Injection valve connector connecting condition.
