What is the cause of the serious blockage of the air conditioner filter?
Air conditioning refrigeration effect is not good, generally for two reasons; 1, the snow is not enough, or the snow is added too much. 2, the external heat sink is dirty, it is blocked, it is not very hot.
It's probably a compressor that's not working, it's probably a compressor capacitor, it's just a fan.
1, with your screen, it will cause indoor heat exchanger coil frost, so after the fan blowing out, will be a little cold, you feel is the refrigeration effect is not too, after washing, increase air volume, not refrigeration, is owing to lack of freon, should add fluoride. The cost is 150 ~ 180 yuan. This is the most likely scenario. 2, due to the filter clogging, easy to cause overcurrent, compressor, the compressor does not work, but the outdoor fan and indication is normal, this kind of situation usually one hour, air conditioning will start automatically, restore normal refrigeration. The compressor capacitance is broken, the compressor cannot start, go to market to buy one, need 15 yuan. 4, if compressor capacitance is not bad, the multimeter measure the resistance of the compressor three terminal, if one is equal to two and even normal, but if there is a short circuit or infinity, the compressor was broken, meaningless, maintenance in one.
