The GREE compressor is humming. It doesn't start. Every time it hums, the lights in the house flash. What's wrong with the capacitor?
Is there a fault indication? No, it may be too cold, the outdoor machine cream, winter cold weather, air conditioning will not immediately start work, to defrost, boot and so on about 20 minutes to see, but also start. The light flash is because the compressor starts to work, the instantaneous current is big, later, opens the air conditioning to try again. It's estimated that a repairman will go to see it.
Not your home circuit problems, that is, compressor problems, specifically called maintenance personnel to check
A buzz can be heard to show that the motor still generates enough starting torque. It can also be determined that the starting capacitor is not bad. (a simple way to judge the quality of the capacitor is to replace the fault with a capacitor of the same type, or if the capacitor is good or can be measured by a multimeter).The reason why the compressor does not start is:1, high pressure side pressure is too high;2, compressor internal moving parts stuck (commonly known as card cylinder).DC resistance inside the compressor motor starting current is very small, very big, if not start, the current will cause the line drop is too large, the same network of light was dim, the thermal protector action while the current order of the compressor, the compressor motor voltage cut off circuit, with the net return to normal, the brightness of the lights will resume normal.Judgment method:1, high pressure side pressure is too high:A, some lack of capacity of maintenance personnel in the face of cooling (or heating) the general performance decline, not a comprehensive review and analysis of reasons, add refrigerant blindly (refrigerant Freon), and due to poor equipment cannot be quantitatively control, cause the system pressure is too large. With this type of maintenance history, first remove some of the refrigerant and try to start the air conditioner.B, system dirty block or ice jam. Small air conditioners are generally throttled by capillary tubes. There is a drying filter in front of the capillary, which is easy to block".C, non fault: high pressure valve is not completely open, a part of the non professional operation of air conditioning machine.2, cylinder:Causes are more complex, generally because the compressor movement parts lack lubrication, local overheating lead to.
