Inverter air conditioning style fan capacitor replacement method: 1, single-phase motor to connect the capacitor, the method is very simple, first in the case of power failure, use a multimeter to measure the three lines of the motor, separated from the main winding, secondary winding, the common end. In the main winding and secondary winding, the indirect capacitance can be used, and the leading end of the main winding is connected to the phase line, and the common end is connected to the neutral line.

2, first open the external top cover, check the capacity of the capacitor, find the same size capacity of the replacement, if the capacitor is too small, the air conditioner can not start, if too large, the compressor will be damaged. All operation steps are carried out when the plug of the inner machine is unplugged. Do not touch the wiring port of the original capacitor during operation, otherwise it may lead to electric shock.

3, generally two terminals, the port regardless of direction, one side is connected to the neutral line, that is, two lines, the internal machine to come, the other port can be connected to the compressor. Appliance maintenance is risky. It is not recommended that customers repair themselves, please grasp every step of the operation to avoid accidents. Especially low-altitude exterior walls and high-altitude work.
The fan capacitance of the variable frequency air conditioner can be changed as follows:
1. If the compressor line is red, yellow and black:
(1) Insert the red wire into the compressor capacitor and connect the first red wire to the male end.
(2) The yellow line is connected to the other section of the capacitor.
(3) As for the black wire, it is directly connected to the second chip from the left on the terminal board (that is, the second black wire connected to the fan motor is the same port).
2, if the compressor line is blue yellow brown:
(1) is to insert the chip of the blue wire into the compressor capacitor and connect the first red wire to the male chip.
(2) The yellow line is connected to the other section of the capacitor.
(3) As for the brown wire, it is directly connected to the second chip from the left on the terminal board (that is, the second black wire connected to the fan motor is the same port).
