1. The phenomenon that the starting capacitor of the air conditioner compressor is broken
1. The compressor can be started but then stopped. The starting capacitor of some air conditioners is broken, and the compressor can be started normally, but there will be a lot of noise, and the vibration is very obvious, and then there will be a phenomenon of stalling.
2. The external machine does not run directly, the air conditioner cannot be cooled, and some fault codes will appear, such as high voltage protection, high temperature of the exhaust pipe, etc. It is usually because the starting capacitor of the external motor is broken. caused.
3. The air switch is tripped. Some air conditioners will also be accompanied by tripping, because there are many reasons for capacitor damage, and some have a breakdown phenomenon, which may cause a short circuit and start the protection switch in the home.
Second, the reason for the failure of the starting capacitor of the air conditioner compressor
1. The capacitor is damaged (short circuit, open circuit).
2. The capacitor specification does not match the compressor.
3. The voltage is unstable.
Three, the quality detection method of the air-conditioning compressor starting capacitor
The tool to be used when measuring whether there is a problem with the air-conditioning capacitor is our Well-known analog multimeter ohm range. So how to use this tool?
First of all, it is necessary to determine the positive and negative machine when using it. Then zero the multimeter. After zero adjustment, the corresponding positive and negative stages can be connected to the air conditioner capacitor. If the pointer swings slowly when connecting the air conditioner capacitor, and finally returns to zero, then there is a problem with the air conditioner capacitor. If the pointer goes directly to infinity when connected, and does not go to zero, then there is a problem with the air conditioner capacitance meter. If the pointer does not swing to zero or infinity when connected, it swings for a period of time. If it returns to a certain value later, it means that the air conditioner capacitor is good. If it is encountered that the pointer reaches zero or infinity after a period of deflection, then the air conditioning capacitor needs to be replaced.
Then if you want to replace the air conditioner capacitor, of course, the best choice of air conditioner capacitor is the original air conditioner capacitor. You can go to the air conditioner repair shop to ask if there is a matching air conditioner capacitor of the brand and style you use. If you have one, you can buy this type of air conditioner capacitor directly. Because the matching accessories are used, not only the effect will not be much different, but also may achieve the same effect as the original air conditioner. However, if the brand is different, it may not be suitable for the current air conditioner.
Fourth, how to replace the starting capacitor of the air conditioner compressor
1. Power off first, be sure to cut off the power first to ensure a safe situation.
2. Prepare tools and new capacitors, go to the outdoor unit, remove the top cover of the outdoor unit, you can see the top of the end with wires, remove the screws that fix the capacitor, and clamp the terminals with pliers Unplug the connection, remember the color position, so as not to install it wrong. If you are afraid of making a mistake, unplug one and install it directly on the new capacitor. If the original capacitor does not completely fail, there may be residual power, so pay attention to safety.
3. After the replacement, first power on and start it, if it is normal, then fix the upper cover.
The air conditioner compressor is very important to the air conditioner. If there is a problem with the starting capacitor, the air conditioner will not work normally. Replacing the starting capacitor, so it is very important to master the replacement of the starting capacitor of the air conditioner compressor.
