Air Conditioning System Electrical Components

AC Capacitor

The AC capacitor in your AC system stores and manages electrical energy from the main power supply. It plays a crucial role in maintaining a consistent power supply for efficient operation and facilitating the start and continuous operation of fans when needed. A typical AC capacitor unit consists of a starting capacitor, responsible for powering up the motor during cooling cycles, and a running capacitor, which helps keep the motor running at a steady pace.

AC Contactors

AC contactors are essential for regulating the flow of electricity within the AC system. They serve the vital function of controlling the power supply, either by cutting it off or supplying it as required. When the cooling system is switched off, the contactor remains in the 'up' position to disconnect the power. As soon as the cooling cycle initiates, the thermostat signals the contactor to move to the 'down' position, allowing electricity to flow.

AC Relays

AC relays are responsible for determining the timing of electrical circuit openings and closures, which in turn controls the current flow in the AC system. Time delays enable the blower motor to continue running even when the compressor is off. This continuous motor operation contributes to the cooling effect on the evaporator, resulting in additional chilled air and improved overall efficiency.

AC Fan Motor

The AC fan motor is responsible for the circulation of air in and out of your living spaces. It plays a vital role in maintaining comfortable indoor temperatures, humidity levels, and air quality. The fan motor includes built-in overload protection within its windings to prevent extensive overheating damage.

Crankcase Heater

The crankcase heater is an electric resistance heater connected to the main power supply of the AC system. It may remain active even when the system is turned off. Its primary purpose is to maintain the refrigerant at a temperature slightly higher than the coldest part of the system and prevent the refrigerant from migrating back into the condenser.

AC Thermostat

The AC thermostat is a well-known component that monitors and controls indoor temperatures. When the indoor temperature falls below the set threshold, the thermostat's contacts close, prompting the contactors to signal the compressor to start. Once the desired temperature is reached, the thermostat contacts open, deactivating the compressor.

Pressure Switches

Pressure switches serve as safety components, continuously monitoring variations in refrigeration pressure to protect the compressor from extremely low or high pressures. High pressure can lead to overheating, while low pressure can result in mechanical damage. In cases of sudden pressure changes, the switches communicate with the contactor, leading to the compressor's shutdown.


DIY Tips for Minor AC Repairs

  • Breaker Check: Begin by inspecting your breaker for any tripped fuses.
  • Thermostat Review: Check your thermostat's position and temperature settings. It might simply need fresh batteries.
  • Filter Inspection: Examine the air filter, and if needed, replace it. This can boost efficiency and airflow.
  • Address Ice Buildup: If you notice ice in the unit, set the system to the fan mode to melt the ice, or turn off the unit to let it thaw.
  • Duct and Register Maintenance: Ensure that ducts and registers are clean, allowing for unobstructed airflow. Verify that registers are clear and open.
  • If issues persist, reach out to Russell Plumbing & Air Conditioning for professional assistance.
