Understanding The Wiring Diagram Of Coleman Mach 15 Air Conditioner


The Coleman Mach 15 air conditioner has the ability to cool your RV or trailer in even the hottest climates. It features an integrated control panel with a digital thermostat and fan motor to regulate temperature. But like all electrical appliances, it needs to be properly wired to operate correctly. This is where the wiring diagram of the Coleman Mach 15 air conditioner comes into play.

In this article, we will discuss the wiring diagram of the Coleman Mach 15 Air Conditioner and explain how it works. We will explain the components, their connections, and how to safely install and wire the appliance. Finally, we will discuss how proper air conditioning maintenance can help to prolong the life of the unit and improve its efficiency.

Understanding the Components of the Wiring Diagram


The wiring diagram of the Coleman Mach 15 Air Conditioner will show the various components that make up the unit and their connections. The diagram will also show the power sources and the connections between them, from the power source to the outdoor condenser unit and the indoor fan coil unit.

The wiring diagram of the Coleman Mach 15 Air Conditioner includes the following components:

  • Outdoor condenser unit

  • Indoor fan coil unit

  • Power source



Outdoor Condenser Unit


The outdoor condenser unit of the Coleman Mach 15 Air Conditioner is responsible for cooling the incoming air. It is powered by a 110/115 volt electric motor connected to the power source. The motor is also connected to a compressor, which is responsible for compressing the refrigerant and circulating it throughout the system. The condenser unit is made up of an evaporator coil, a compressor, an expansion valve, and a condenser coil.

The evaporator coil is responsible for absorbing heat from the incoming air, which is then sent to the compressor. The compressor compresses the refrigerant and sends it to the condenser coil, which dissipates the heat from the refrigerant. The expansion valve then regulates the flow of the refrigerant, controlling the temperature of the air that is discharged from the outdoor condenser unit.

Indoor Fan Coil Unit


The indoor fan coil unit of the Coleman Mach 15 Air Conditioner is responsible for distributing cooled air throughout the RV or trailer. It is powered by a 110/115 volt electric motor, and is connected to the compressor of the outdoor condenser unit. The fan coil unit consists of two coils; an evaporator coil and a condenser coil. The evaporator coil absorbs heat from the air and sends it to the compressor, while the condenser coil dissipates the heat from the refrigerant.

The fan coil unit also includes a filter, which is responsible for filtering out particles before the air enters the system. This helps to keep the air clean and free of dust and dirt. The fan coil unit also controls the speed of the fan, which helps regulate the temperature of the air that is distributed throughout the RV or trailer.

Power Source


The power source of the Coleman Mach 15 Air Conditioner is responsible for supplying electricity to the unit. It is typically connected to a 110/115 volt outlet, or a 30 amp or 50 amp circuit breaker. It is important to make sure that the power source is properly wired and meets the safety requirements outlined by the National Electrical Code. This ensures that the unit is properly powered and is safe to operate.

Installing and Wiring the Coleman Mach 15 Air Conditioner


When installing and wiring the Coleman Mach 15 Air Conditioner, it is important to follow the manufacturer’s instructions. All electrical connections should be done carefully to ensure a secure and safe installation. Once the unit has been installed, it is important to check the wiring diagram to make sure that all of the components are properly connected. This is the best way to ensure proper operation of the unit.

Air Conditioning Maintenance


Proper air conditioning maintenance is key to prolonging the life of the Coleman Mach 15 Air Conditioner and improving its efficiency. Regularly cleaning and inspecting the unit, as well as replacing the filters, will help improve the performance of the unit and reduce the amount of energy it uses. Additionally, it is important to regularly inspect the wiring and make sure that all of the components are securely connected.

In conclusion, understanding the wiring diagram of the Coleman Mach 15 Air Conditioner is essential for proper installation and wiring of the unit. Proper air conditioning maintenance can help extend the life of the unit and improve its efficiency. By following the manufacturer’s instructions and regularly inspecting the wiring, you can ensure that the unit is properly powered and safely operating.
