The indoor temperature does not drop after Gree air conditioner starts and runs for 2 hours in cooling mode.
Analysis and Maintenance: The outdoor ambient temperature at the time was measured to be 30℃, with the air conditioner set at 25℃. Pressure and current were detected as normal, and the condensation condition of the evaporator was good. The temperature difference between the inlet and outlet vents was 9℃, and the resistance value of the indoor temperature sensor was also normal. Upon checking the outdoor unit, the Beijing Gree Air Conditioning After-sales Service Hotline found that the outdoor unit was directly facing the kitchen exhaust vent. It was suspected that the poor heat exchange of the condenser was causing the issue. After reinstallation of the unit in a different location, the air conditioner worked normally, and the fault was eliminated.
Tip: When selecting the installation position for the outdoor unit, try to avoid areas with high-temperature heat sources.
