What are the symptoms of the capacitor fault in the air conditioner

There are two capacitors in the outdoor unit electric packing box, the large volume is the compressor capacitance, the small volume is the external motor capacitance. Different capacitor damage failure phenomenon is also different: Compressor capacitance damage: the performance of normal compressor startup will be accompanied by greater noise and jitter, if the capacitance damage. Hands on the upper shell of the compressor will feel the compressor have a slight shake sound like the sound of electricity passing through the compressor after a period of time after the compressor stopped operation. 2. External Motor capacitance damage: the performance phenomenon is that after the compressor works normally, the external machine stops working for a period of time. If there is a fault code, there will be brought up pressure protection, compressor exhaust pipe temperature protection.
