Air conditioning does not cool:
1. Due to the high external temperature, it cannot be cooled.
2. Air conditioning power is insufficient.
3. The power supply voltage is insufficient.
I haven't cleaned the air conditioner for a long time.
5. "Snow seed" is not enough.
6. The copper tube between the outdoor unit and the indoor unit is too long.
7. The air conditioning system is blocked, causing throttling expansion at the blocked place.
8. The air conditioner compressor does not work, resulting in the air conditioner not cooling.
Air conditioning fan fault: fan capacitor fault, fan motor fault, line fault, computer board fault. Wait a minute.
