Key Components and Structure of a Coleman Evcon Wiring Diagram

A typical Coleman Evcon air conditioner wiring diagram includes several important components and symbols. Familiarizing yourself with these elements is crucial for proper interpretation:

• Power Supply: Indicates the voltage and current supplied to the unit.
• Transformer: Steps down the voltage for control circuits.
• Capacitors: Stores electrical energy for starting and running the motor.
• Compressor: The heart of the cooling system, responsible for circulating refrigerant.
• Fan Motors: Controls the airflow across the evaporator and condenser coils.
• Relays and Contactors: Switches used to control high-voltage components.
• Thermostat: Senses the room temperature and controls the air conditioner operation.
• Fuses and Circuit Breakers: Protect the electrical components from overloads.
• Wiring Colors: Standardized color coding helps identify wire functions (e.g., black for line, white for neutral, green for ground).
• Schematic Symbols: Represents electrical components like resistors, diodes, and switches.

Practical Application

Using the Coleman Evcon air conditioner wiring diagram correctly allows for efficient troubleshooting and repair. Here’s a practical example:

1. Identify the Problem: For instance, the fan motor isn’t running.
2. Consult the Diagram: Locate the fan motor circuit on the wiring diagram.
3. Check Power Supply: Use a multimeter to verify voltage at the motor terminals.
4. Inspect Components: Check the capacitor, relay, and wiring connections in the circuit.
5. Isolate the Fault: If voltage is present, the motor might be faulty. If not, trace the circuit back to find the break.
6. Replace the Component: Once the faulty component is identified, replace it with a new one.

1. Troubleshooting Common Issues Using the Wiring Diagram

The Coleman Evcon air conditioner wiring diagram is invaluable for troubleshooting these common issues:

• Air Conditioner Not Turning On: Check the power supply, thermostat, and circuit breaker.
