A: During cooling mode, the outdoor unit of the Mijia Air Conditioner Pro Eco Inverter 1.5 HP does not normally produce condensate. However, if you notice water dripping from the outdoor unit while cooling, it is likely due to parts of the outdoor piping reaching low temperatures. When the outdoor humidity is high, condensation can form on these cold pipes. The water then drips onto the base tray and drains through the outlet, which is a normal occurrence and does not require repair.
In heating mode, the outdoor unit can frost over, and the defrosting process can produce condensate. This is also considered normal.

Observe if the outdoor unit is located in a confined or narrow space where heat dissipation is poor, causing the outdoor environment temperature to be too high or too low. If heat dissipation is confirmed to be poor, move the outdoor unit to ensure proper ventilation and heat dissipation; 3. If this code appears when the ambient temperature of the overall unit is within the normal range, it indicates that the outdoor ambient temperature sensor is faulty, resulting in inaccurate temperature sampling. First, replace the outdoor ambient temperature sensor. If replacing the sensor does not clear the fault, replace the outdoor power board. | |
