What's a dual run AC capacitor ?

• A capacitor is an electric component that temporarily stores an electrical charge and AC capacitor is a key component to start air conditioner motors.
• A dual run capacitor supports "TWO" electric motors, one section for the condenser fan motor and the other for the compressor motor. Beacause of technological innovation, the dual run capacitor can saves space by combining two capacitors into one case.
• Round cylinder-shaped dual run capacitors are commonly used for air conditioning, it can help in the starting of the compressor and the condenser fan motor.
• Air conditioner capacitor is small in size, lightweight, heat resisting and anti-explosion.

Dual capacitors come in a variety of sizes, depending on the capacitance (µF or MFD) and the voltage.

1. The capacitance (µF or MFD) must be the same or stay within ±6% of its original value. Example: 45 µF cap can be substituted by 42.3 to 47.7 µF with the same or better voltage ratings capacitor .
2. A 440 volt capacitor can be used in place of a 370 volt capacitor, as it can work better, but the 370 volt capacitor can't be used in place of a 440 volt capacitor.It will work for a while or will fail prematurely, because exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out.

"TIME" to Replace

The Dual Run AC Capacitor needs to be replaced when the following conditions occur:

1. The fan wouldn't spin - the condenser fan motor maybe died.
2. The air conditioner is making humming sound, but no air flow.
3. Air conditioner stopped cooling - the compressor in the condenser maybe not coming on.

"SUPER EASY" to Install

• First, Shut off power to the A/C at both the thermostat and the breaker box. Secondly, taking out the capacitor.
• What's important, make sure you know which wire is for which terminal - three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan and "C" for the common line.
• Direct replacement, no need to change wiring or adapter.
• Last but not least, self-install will save you a substantial amount of money!

What is the role of capacitors for motors?

The common occasion to use capacitor on the general motor is the start of single-phase motor, this capacitor is also called start capacitor, from the circuit principle, it plays the role of phase shifting, because the single-phase motor has only one set of running winding, the rotor is squirrel cage type, single-phase electricity can not produce a rotating magnetic field, need another set of start winding to match, because there is only single-phase 220 volt AC, so the start winding is connected in series with A capacitor, the characteristics of the capacitor is that the voltage can not change abruptly, so it will let the starting coil current ahead of the running coil 90 °, so that two rotating magnetic fields can be formed in space, so that the motor starts normally.

The stator of single-phase motor has two groups, which are 90 degrees apart in space, respectively the starting winding and the running winding, which can obtain the current with 90 degrees difference. Under the phase shifting effect of the starting capacitor, the single-phase electricity will make the current of the starting winding and the running winding differ by 90 degrees phase difference, which produces a rotating magnetic field in the stator space, and the rotor will cut the magnetic lines of force and produce current, which in turn will have a rotating magnetic field, and the stator-rotor magnetic field The stator-rotor magnetic field interacts with each other, and the rotor can rotate continuously.

Some DC motors are also connected in parallel with a capacitor at both ends of the armature, which is mainly used for filtering and anti-interference. Because the DC motor has carbon brushes, carbon brushes and commutation piece will produce spike voltage when broken, capacitor added to release this voltage, of course, there are also some in the carbon brush and ground between the capacitor can also play a similar role.

One use of capacitor for motor is reactive power compensation, the motor is inductive load, the power factor is relatively low after use, the power supply room need to use capacitor to do reactive power compensation. And the long-distance reactive power compensation loss is relatively large, the effect is not too good, so sometimes need to do directly in the vicinity of the motor to start reactive power in situ compensation, such as the following star-delta starting circuit, plus capacitors to complete this function.

In-situ reactive power compensation directly makes the power consumption smaller and the power factor significantly higher, fully enhancing the potential of the grid transmission.

How to distinguish between starting capacitor and running capacitor?

Different state after the motor starts

After the motor starts, the starting capacitor is disconnected by the separation switch, while the running capacitor is involved in operation with the starting coil.

Different capacity

The starting capacitor has a capacity of about 200 microfarads and the running capacitor has a capacity of about 20-30 microfarads.

Different function

The starting capacitor is to let the starting coil of a single motor energize during starting and cut off after starting, while the running capacitor is to let the motor play capacitive compensation during running, the starting capacitor cannot be missing, while the running capacitor can be unnecessary.
