The old capacitor was very swollen and looked like a soda can that had been repeatedly shaken up. Be sure to write down which wires go to what terminal on your capacitor before removing the old one or just take a few pictures. For home air conditioning systems that use dual run capacitors they will have 3 terminals. The terminal labeled "HERM" is for the yellow wire that goes to the "Hermetically Sealed" compressor. The "FAN" terminal gets connected to the brown wire that goes to the condenser fan. Finally the "COM" terminal is for the purple and red wires that go to the contactor and provide power to the capacitor.
What else can I help you with?
Can a 3 pole c herm fan capacitor be used to replace a 2 pole capacitor on a home air unit if the mf's and voltage are the same?
I am going to assume that the capacitor in question has one uf or mfd rating and the one you want to use has two such as: 30+7.5uf if so then yet as long as you hook to the terminals that supply the same uf as the oem capacitor. The terminal marked HERM will be the terminal that has the highest of the two uf ratings. hope this helps!!
Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.
Why does the reactance of a capacitor decrease with frequency?
Because reactance of capacitor is inversly proportional to the frequency i.e- Xc=1/(2*pie*f*c) where f is frequency and c is capacitance of capacitor.
How do you wire a run cap for an ac unit?
To wire a run capacitor for an AC unit, first, ensure the power is turned off to the unit. Identify the capacitor terminals, typically labeled "C" (common), "H" (high), and "L" (low). Connect the common wire from the compressor and fan to the "C" terminal, the wire from the compressor to the "H" terminal, and the wire from the fan to the "L" terminal. Finally, secure all connections and restore power to test the unit.
What are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.

How do you install a 5-2-1 3 wire hard start AC capacitor?
To install a 5-2-1 3-wire hard start capacitor, first, ensure the power to the AC unit is turned off at the circuit breaker. Remove the existing capacitor by noting the wiring configuration and disconnecting the wires. Then, connect the new capacitor according to the labeling on its terminals: typically, the "HERM" (hermetically sealed compressor), "C" (common), and "FAN" (fan motor) connections should match the old setup. Finally, securely mount the capacitor, double-check all connections, and restore power to test the system.
Why is the a/c fan not spinning?
The A/C fan may not be spinning due to a malfunction in the motor, a broken belt, or a faulty capacitor. It is important to have a professional inspect and repair the fan to ensure proper functioning of the air conditioning system.
Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.
What is the potential difference formula for a capacitor?
The potential difference formula for a capacitor is V Q/C, where V is the potential difference (voltage), Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
What does C in electrical language mean?
Capacitor (a passive electronic component). Or Coulomb (unit of electric charge).
What could cause the compressor to come on but the fan to stop rotating on a central air conditioning unit if you touch the fan blade it will start working again and then blow cold air again?
The fan motor is bad. The fan motor capacitor may also be the problem. First, an amperage test should be done on the motor to see if its exceeding the rated amps. Secondly, the capacitor should be tested for the amount of microfarads it has. If its an old mtor, it should be replaced, along with the capacitor. All of this should be done by a licensed A/C contractor!
How can you calculate the energy stored in a capacitor?

How to calculate the potential difference across a capacitor?
To calculate the potential difference across a capacitor, you can use the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
How you find capacitance of ceiling fan through formula though it is running 220V 50Hz and as written on capacitor of 2.5uf but how from formulation?
To find the capacitance of a ceiling fan, you can use the formula for capacitive reactance, which is ( X_C = \frac{1}{2\pi f C} ), where ( X_C ) is the capacitive reactance, ( f ) is the frequency in hertz, and ( C ) is the capacitance in farads. Given that the capacitor is rated at 2.5 µF, you can convert this to farads (2.5 µF = 2.5 x 10^-6 F). Using the frequency of 50 Hz, you can calculate the capacitive reactance and confirm that the capacitor value is appropriate for the ceiling fan's operation. However, the primary value of capacitance is already provided by the capacitor itself.
