Wiring The Coleman Rv Air Conditioner
Wiring the Coleman RV Air Conditioner can seem complex. Yet, with a clear guide, it becomes manageable. This section will cover the key steps to wiring your Coleman RV air conditioner. We’ll focus on connecting the power supply and wiring the thermostat.
Connecting Power Supply
First, locate the main power supply. Ensure it is turned off to avoid any danger. Find the black and white wires from your RV’s power source. Connect the black wire to the black wire on the air conditioner. Next, connect the white wire to the air conditioner’s white wire. Use wire nuts to secure these connections.
Finally, locate the ground wire, typically green or bare. Attach it to the grounding screw in the air conditioner’s junction box. Double-check all connections to ensure they are tight and secure. Turn the power back on and test the air conditioner.
Wiring The Thermostat
Begin by identifying the thermostat wires. These are usually color-coded. Common colors include red, yellow, green, and white. Connect the red wire to the terminal marked “R” on the thermostat. Attach the yellow wire to the “Y” terminal.
Next, connect the green wire to the “G” terminal. Finally, attach the white wire to the “W” terminal. Secure all connections with wire nuts. Install the thermostat on a wall inside your RV. Ensure it is in a central location for accurate temperature readings.
Once installed, test the thermostat. Set your desired temperature and ensure the air conditioner responds correctly. Proper wiring ensures your Coleman RV air conditioner runs smoothly.

Testing The Installation
Testing the installation of your Coleman RV air conditioner is crucial. This step ensures your unit functions correctly and efficiently. It involves two main tasks: the initial power-on and checking for proper operation. Let’s dive into each task to ensure your air conditioner is set up perfectly.
Initial Power-on
First, connect your Coleman RV air conditioner to the power source. Ensure all wiring connections are secure. Turn on the power supply and wait a few seconds. Listen for any unusual sounds. These could indicate wiring issues.
Next, check the control panel. It should light up and respond to your inputs. If the panel remains unresponsive, recheck your wiring connections. Ensure the power supply is stable. This step verifies that your air conditioner receives power correctly.
Checking For Proper Operation
Set the thermostat to a low temperature. This triggers the air conditioner to start cooling. Feel the air coming from the vents. It should be cool and steady. If the air is warm, check the coolant levels and compressor function.
Observe the fan speed settings. Switch between low, medium, and high. Ensure the fan responds accurately to each setting. This confirms the control system works properly.
Listen for any unusual noises during operation. Rattling or humming sounds may indicate loose parts or wiring issues. Address these immediately to prevent further damage.
Finally, check the airflow from all vents. Ensure there are no blockages. Proper airflow ensures efficient cooling throughout your RV. If any vent shows weak airflow, inspect the ductwork for obstructions.
By following these steps, you ensure your Coleman RV air conditioner is installed correctly. Enjoy a cool and comfortable RV experience.
