What is a Carrier Air Handler Wiring Diagram?
Carrier air handlers are responsible for circulating air inside the HVAC system. The wiring diagram for a Carrier air handler provides a visual representation of the electrical components and their connections. This diagram is essential for troubleshooting electrical problems and installing new electrical components.
Components of a Carrier Air Handler Wiring Diagram
Before diving into the details of the Carrier air handler wiring diagram, it’s important to familiarize yourself with the different components that make up the diagram. These components include the power supply, control transformer, relay, blower motor, heat strips, sequencer, and thermostat.
Power Supply
The power supply provides the necessary electrical current to the air handler. This component is usually connected to a circuit breaker or a fuse box.
Control Transformer
The control transformer reduces the voltage from the power supply to a level that is safe for the air handler’s electrical components.
Relay
The relay is an electrical switch that controls the flow of current to the blower motor and other components in the air handler.
Blower Motor
The blower motor is responsible for circulating air through the HVAC system. This component is typically controlled by the thermostat and the relay.
Heat Strips
The heat strips are electrical heating elements that provide supplemental heat to the air handler. These components are typically used in cold weather to provide additional heat when the air handler’s primary heating system is not sufficient.
Sequencer
The sequencer is an electrical component that controls the timing of the heat strips. This component ensures that the heat strips turn on and off at the appropriate times to provide efficient heating.
Thermostat
The thermostat is a control device that regulates the temperature within the HVAC system. This component is usually installed in a convenient location and allows the user to adjust the temperature to their desired level.
