What Is an AC Capacitor and Why Is It Important?
An AC capacitor is a cylindrical-shaped non-polarising electrical component that stores and releases electrical energy to start and run the compressor and motors of an air conditioner. By acting as a temporary energy reservoir, they help maintain a consistent voltage, keeping the AC running smoothly.
Role of the Capacitor in an Air Conditioning System
A capacitor is an important component that helps in motor starting and keeping the AC running. It plays an instrumental role in preventing system malfunctions or complete failure. The roles include:
- Kickstarting the compressor and fan motors of an air conditioner
- Maintaining a steady voltage supply to keep the AC running
- Acting as a temporary power source to prevent premature motor failure
- Lowering energy usage and minimising stress on internal components
What are the Types of AC Capacitors?
There are generally 5 types of capacitors used in air conditioners, and they are classified based on their function, voltage rating and operation:
Start Capacitor: The start capacitor provides an initial and short-term boost to start the compressor motor. Once the motor reaches at least 70-80% of its running speed, it is automatically disconnected by a switch.
Run Capacitor: A run capacitor is an oil-filled cylindrical component that provides a continuous, steady voltage supply to keep the compressor and motor running.
Dual Capacitor: A dual capacitor combines both a start and a run capacitor into a single component. It saves space and supports both the compressor and the fan motors.
Electrolytic Capacitor: An electrolytic capacitor is a polarised, high-capacitance component used in AC control boards and inverter circuits to smooth out DC voltage fluctuations, store energy, and stabilise the power supply.
Film Capacitor: A film capacitor is a non-polarised electrical component that uses thin plastic films as dielectrics for handling alternating currents, running AC motors, suppressing EMI (electromagnetic interference), and correcting power factor in circuits.
Key Symptoms of a Failing AC Capacitor
A failing AC capacitor can present itself in several ways, such as difficulty starting, humming from the outdoor units, or warm air blowing from the AC. If left unreplaced, a faulty capacitor can lead to complete system failure.
The most common symptoms of a failing AC capacitor are:
- Hard starting of the AC or the unit not starting at all
- Loud humming or buzzing sounds from the outdoor unit
- Warm air blowing from the AC
- Bulging, swelling, or leaking of the capacitor
- Burning odour or smoke from the condenser unit
- Frequent cycling and sudden shutdowns caused by motor overheating
- Rising electricity bills due to increased energy consumption
AC Capacitor Replacement for Different AC Types
The process of air conditioner capacitor replacement is similar for both split and window ACs, but differs depending on the location of internal components and their accessibility.
Split AC Capacitor Replacement
In a split AC, the capacitor is located inside the outdoor condenser unit near the compressor and the fan motor. In case of a faulty capacitor in a split AC, changing AC capacitor involves:
- Ensure the power supply to the outdoor condenser unit is completely switched off
- Opening the outdoor condenser unit, identifying the capacitor, disconnecting the wires, and removing the mounting strap to take out the faulty capacitor
- Install the new capacitor and reconnect all the wires
Window AC Capacitor Replacement
In a window AC, the capacitor is located within the main casing, close to the compressor and motor assembly. Here’s how an AC capacitor replacement works for window ACs:
- Disconnecting the power supply to the window AC
- Removing the outer casing to access internal components
- Safely discharge the capacitor, then disconnect all connected wires
- Install the new capacitor and reattach all wires and panels properly
Note: Air conditioner capacitor replacement should only be handled by professional electricians, as the process involves significant electrical risks.
