Вопрос пользователя How to repair air conditioning does not blow cold air

Вопрос: 
The most common cause of air conditioning does not blow cold air is the lack of adequate airflow.<br> <br> In a conditioner that works properly, the fan will suck air over the coils of the evaporator, where it is cooled and then re-circulated back to the room. If the air filter is dirty or clogged, there is little or no airflow on the evaporator coils, which can cause them to become too cold, restricting airflow more. This will result in little or no cool air being circulated to the room.<br> <br> The inspection steps are as follows:<br> <br> 1 / Fan and fan motor<br> <br> If your air conditioner does not blow cold air, the problem may be a fan or fan motor. In a properly functioning air conditioner, the fan will suck air through the coils to evaporate cold and then re-circulate the air back into the room. If the circulating fans are not running or running too slowly, little or no airflow on the evaporator windings will allow them to become too cold and freeze, limiting air flow more.<br> <br> Fans and motors need to be checked regularly. Make sure the fan motor is stable and the blades are not damaged. If the engine is retained or if the blade is damaged, it will need to be replaced - http://www.google.com/search?q=replaced&btnI=lucky .<br> <br> If the motor rotates easily, it may remain faulty or may not receive power from the controls. This test is more complex and should be done by a professional.<br> <br> 2 / Temperature control<br> <br> The second reason is that you may have a problem with a temperature controller or a thermostat. This is a device that monitors air temperature to and on or off the compressor. Typically, a sensor-attached lightbulb extends to the front of the evaporator coil and mua diều hòa cũ an phúc - http://chuyendieuhoa.com/mua-dieu-hoa-cu-209.html electrical contact in the body of the controller supplies the compressor circuit. The light bulb monitors the ambient air temperature and informs the thermal controller to turn on the compressor when the set temperature is below room temperature. The heat regulator will also shorten the compressor cycle when it reaches the desired temperature.<br> <br> If the temperature controller or thermostat is faulty, it may fail to send power to the compressor and no cooling occurs. You should check the light bulb for signs of severe bending, twisting or breaking and replace the controls if there are any signs.<br> <br> 3 / Capacitor<br> <br> The third cause is potential trouble in the compressor circuit. Most air conditioners use a capacitor to help start the compressor. If the capacitor fails, the compressor will not start and the fan will only blow warm air.<br> <br> If the capacitor does not show any signs of damage, you need to check it with a special test equipment. Ensure that the replacement capacitor has the same specifications as the original.<br> <br> 4 / Thermistor<br> <br> The next cause is that the air conditioner may have problems with the thermistor. This component is found on the electronic control models and monitors the incoming air temperature and signals the main panel to switch on or off the compressor. This device is usually located in airflow near the coil of the evaporator. If the thermal resistance is faulty, it will not provide the proper signal for the control board to turn on the compressor circuit.
