Dometic air conditioners are one of the most popular air conditioning systems used in recreational vehicles and boats. They provide efficient cooling and are known for their durability and reliability. In this article, we will discuss the wiring diagram for Dometic air conditioner and some commonly asked questions about it.
Understanding the Wiring Diagram
The wiring diagram for a Dometic air conditioner consists of several components. These components include the compressor, fan, thermostat, capacitor, and transformer. Each component is connected to the other in a specific sequence to make the air conditioner work efficiently.
The wiring diagram will show how each component is connected to the other, which wire is connected to which terminal, and the colors of the wires. It is important to follow the wiring diagram to avoid any confusion or error that may result in damage to the air conditioner or injury to the technician.
Before attempting to wire the air conditioner, make sure to turn off the power at the circuit breaker or disconnect switch. This will ensure your safety and prevent any electrical mishap.
Let us look at each component and its connection in detail.
The Compressor
The compressor is the most important component of an air conditioner as it is responsible for compressing the refrigerant gas and circulating it through the system. The compressor is usually located in the outdoor unit and is connected to the power supply through the contactor.
To wire the compressor, connect the power supply wires to the contactor and then connect the contactor to the compressor. The wiring diagram will show which wire is connected to which terminal of the contactor and the compressor.
The Fan
The fan is responsible for blowing the cold air into the room and sucking in the warm air. The fan motor is located in the outdoor unit and is connected to the power supply through the capacitor and the contactor.
To wire the fan, connect the power supply wires to the contactor and then connect the capacitor to the contactor and the fan motor. The wiring diagram will show which wire is connected to which terminal of the capacitor, contactor, and fan motor.
The Thermostat
The thermostat is the device that controls the temperature of the room. It is connected to the indoor unit and can be manually or electronically controlled. The thermostat is connected to the power supply through the transformer.
To wire the thermostat, connect the power supply wires to the transformer and then connect the transformer to the thermostat. The wiring diagram will show which wire is connected to which terminal of the transformer and the thermostat.
The Capacitor
The capacitor is a device that stores electrical energy and releases it when required. It is used to start the compressor and the fan motor. The capacitor is connected to the power supply and the fan motor or compressor.
To wire the capacitor, connect the power supply wires to the capacitor and then connect the capacitor to the fan motor or compressor. The wiring diagram will show which wire is connected to which terminal of the capacitor and the fan motor or compressor.
The Transformer
The transformer is a device that converts high-voltage electricity to low-voltage electricity. It is used to power the thermostat and other low-voltage components of the air conditioner. The transformer is connected to the power supply and the thermostat.
To wire the transformer, connect the power supply wires to the transformer and then connect the transformer to the thermostat. The wiring diagram will show which wire is connected to which terminal of the transformer and the thermostat.
