A method for judging the quality of the air conditioner capacitor(I)

Vacant capacitors are closely related to our daily life, such as TV sets, LED lights, switching power supplies and so on. Air conditioning is the starting function of external capacitors. Do you all know? If the capacitor is broken, the whole air-conditioner will not be refrigerated, which is also the most common malfunction of air conditioning without refrigeration or heating. In daily maintenance, how do we judge the quality of the capacitor? If the air conditioning capacitor is broken, it can be seen from the appearance. Some capacitors are drums and leaks, which can be seen from the outside. Some need capacitance meter to measure, because he looks good, and must be measured by professional tools.

The methods to judge the good and bad of the capacitor are as follows:

1. The most direct and simplest way is to connect directly with 220V alternating current. It can pick up one pole first and use another power line to touch another capacitance foot. If there is a slight spark at the touch, it is certain that the capacitor is charged, that is to say, the capacitor is not damaged.
