Can't lower cooling temp

Is you indoor fan running? Is the out door unit running? (Condensing Unit) If both are true, is the larger of the two copper lines on the Condensing Unit colder than the smaller one? If not, is the compressor in the Condensing Unit running? The compressor is the big can under the fan in the Condensing Unit. Please reply to this as you may need a service tech. at this point.

Ice forming on front coil of aircon blower

the front coil or evaporator is not absorbing heat from the conditioned space or the condensing coil or back one is not rejecting heat. usually this is due to dirty coils or clogged filters

Outdoor fan is running continuously without using Wireless Remote Controller

Bad control board on the condensing unit up top. The board needs to be replaced as it is sending the message that the system is calling for cooling/heating all the time and doesnt know what to do. If you continue to let it run this way you will ed up having more major issues

Yeah, only a qualified or pro aircon tech can replace it. Also the evaporator coil needs to be check for leak. If your unit is still under warranty better call the manufacturer. Anyway, here's how aircon works:

Window air conditioners work on exactly the same principles as a refrigerator or dehumidifier. They have a cooling system that refrigerates the air entering the unit. The moisture in the air condenses on the cold coils and drips into the bottom tray of the air conditioner. The warm air in the room is drawn over the evaporator coil, which collect heat. The heat is conducted into a refrigerant gas. The gas is then circulated to the condensing coils on the back of the unit where it is dissipated to the outside.
