# Run Capacitor vs. Start Capacitor: What’s the Difference?
When it comes to your home’s air conditioning system, it’s important to pay attention to the specifics of maintaining and repairing it. Comprehending the subtle details of the parts – from the compressor to the condenser – can mean the difference between having a functional system and expensive and inconvenient emergency repairs.
In this article, we’ll delve into the differences between the two types of capacitors typically found in air conditioning systems: run capacitors and start capacitors. We’ll also explain what purpose each capacitor serves and the specific ways they operate so that you can better understand how they work and when they should be checked and replaced.
## What is a Capacitor?
A capacitor is an electrical component made of two metal plates separated by an insulating layer or dielectric. Capacitors are used to store and discharge electrical energy. In air conditioning systems, they are used in place of the traditional motor winding and can serve several purposes.
## What is a Start Capacitor?
Start capacitors are needed for air-conditioner motors that use single-phase power. The purpose of a start capacitor is to briefly increase the motor’s torque up to five to seven times its normal amount to help start the motor and get it spinning at the correct speed.
Start capacitors come in a range of sizes, typically from 40 µF (micromicrofarads) to 1200 µF. The larger the capacitor, the more torque it will produce and the easier it will be for it to start. Start capacitors are also rated for a certain voltage range and usually handle a range of 110 to 125 volts.
## What is a Run Capacitor?
Run capacitors work differently than start capacitors because they’re designed to stay running. They use two capacitors wired in series to form what is known as a dual-capacitor system. The two capacitors in the run capacitor can be unequal capacitor values, or they can be the same.
Run capacitors come in a range of sizes, usually from 7.5 µF to 70 µF, and their capacitance is usually rated for a range of 208 to 253 volts. The purpose of run capacitors is to keep a steady voltage and current flowing to the compressor motor and fan motor.
## How Do Start Capacitors and Run Capacitors Work Together?
When the start switch is closed, both the start and run capacitors are trying to start the motor. The start capacitor provides a large electrical boost so the motor can start up and then the run capacitor takes over and provides the steady voltage and current needed for the motor to keep running. Once the motor is going, the start capacitor is no longer necessary and the run capacitor will take over.
When the start switch is opened, the start capacitor will be disconnected from the circuit and the run capacitor left in place to provide power to the motor. This allows the motor to keep running without having to perform the large electrical surge every time it starts.
Both the start and run capacitors should be checked every few months and replaced when necessary. In addition, it’s important to make sure the right size capacitors are used to ensure that the operation of the air conditioner is at its most efficient.
## When Should a Start Capacitor or Run Capacitor Be Replaced?
The most common cause of breakdowns in air conditioners is the failure of either a start capacitor or run capacitor. In such a case, it is recommended that the capacitor be replaced as soon as possible to prevent complications in the air conditioner’s operations.
To determine when a capacitor needs to be replaced, it is important to look for signs such as:
– A buzzing sound coming from the capacitor.
– Black residue that appears on the outside of the capacitor.
– A capacitor that is visibly swollen.
– If your outside A/C unit continues to stop and restart.
These are all signs that the capacitor has failed and should be replaced. It is important to note that capacitors should always be replaced with ones that have the same capacitance value and voltage rating as the original ones.
## Conclusion
To sum up, a start capacitor is used to start the motor of your air conditioning unit, while a run capacitor is used to keep it running. Together, they work to ensure that your air conditioner is able to run smoothly and efficiently. It is important to keep an eye out for signs of failure in either capacitor and to have them replaced as soon as possible.
