Most units experience first serious troubles after five and more years of exploitation. We can introduce you top popular problems so that you can check whether your AC works properly. A common cause of window air conditioners not blowing any air is a restricted air filter. In a properly working air conditioner, a fan will draw air over the evaporator coils, where it is cooled, and then be re-circulated back into the room. If the air filter becomes dirty or clogged, there will be little or no air flow over the evaporator coils, which will cause them to become too cold and frost or ice will form on them, causing the air flow path to be completely restricted. This can result in no air at all being circulated into the room. The air filter is positioned in front of the evaporator which is located behind the front grille. Clean or replace the filter as often as required. If the evaporator coils are very dirty then cleaning them with soapy water and a soft brush will be required and we also recommend changing the filter at the same time. If your air conditioner is running but not blowing any air and you have inspected the air filter and fan motor and found them okay, then you may have a problem with the control board. Sometimes referred to as the PCB, this is an electronic control board that operates the fan motor and compressor circuits using relays mounted on the circuit board. The power output from the relays can be checked with a multi-meter, but this should only be attempted by a qualified person. If the on board relay is defective, or if the processor circuitry is defective then the control board or PCB will need to be replaced. Remember checking your units in time because it might save your time and money.
