Having an AC furnace is a great way to ensure your home stays cool and comfortable during hot weather. However, in order for it to work properly, you need to make sure the wiring is connected correctly. This article will provide a detailed AC furnace wiring diagram to help you properly connect the wiring and ensure your AC furnace works smoothly.
What is an AC furnace wiring diagram?
An AC furnace wiring diagram is a detailed representation of the electrical connections that make up your furnace’s electrical system. It shows how each part is connected and where the wires are located so that you can properly connect each wire to the correct terminal.
The diagram typically includes information about the thermostat, control board, transformer, blower motor, and heat exchanger. It is important to follow the diagram carefully to avoid any electrical issues or damage to your furnace system.
Components of the AC Furnace Wiring Diagram
Thermostat
The thermostat is the component that controls the temperature in your home. It signals the furnace to turn on or off depending on the temperature setting.
The wiring for the thermostat typically includes a red wire for power, a yellow wire for cooling, a white wire for heating, and a green wire for the fan. The wiring for the thermostat should be connected to the control board, which is responsible for sending signals to the various furnace components.
Control Board
The control board is the brain of your furnace system. It receives signals from the thermostat and uses them to control the various components of the furnace.
The wiring for the control board typically includes a low voltage wire for the thermostat, a high voltage wire for the transformer, and wires for the blower motor, gas valve, and flame sensor. Each wire should be connected to the corresponding terminal on the control board to ensure proper functioning.
Transformer
The transformer converts high voltage power into low voltage power for use in the furnace system. It is important to connect the transformer correctly to avoid any electrical issues.
The wiring for the transformer typically includes a primary wire for high voltage power and a secondary wire for low voltage power. These wires should be connected to the corresponding terminals on the control board.
Blower Motor
The blower motor is responsible for circulating air throughout your home. It is important to connect the wiring for the blower motor correctly to ensure proper functioning.
The wiring for the blower motor typically includes three wires: a black wire for high speed, a blue wire for medium speed, and a red wire for low speed. These wires should be connected to the corresponding terminals on the control board.
Heat Exchanger
The heat exchanger is responsible for transferring heat from the furnace to the air circulating throughout your home. It is important to connect the wiring for the heat exchanger correctly to ensure proper functioning.
The wiring for the heat exchanger typically includes a red wire for power and a white wire for the fan. These wires should be connected to the corresponding terminals on the control board.
