How to Troubleshoot a Nordyne Air Conditioner

Common issues include dirty filters and coils, incorrect thermostat settings and power problems. Troubleshooting and maintaining your unit can maximize cooling efficiency and increase its lifespan.

1. Check your outdoor condensing unit and make sure it is plugged into an electrical power source if your Nordyne air conditioner is not turning on. Inspect the unit and make sure it is properly grounded and secure.

2. Check the disconnect switch next to your outdoor condensing unit and make sure it is in the "On" position if your unit is not turning on.

3. Check the coils and the top of your outdoor unit. If they are dirty, connect a hose to a vacuum cleaner and carefully vacuum the coils to remove any dirt and debris. Remove obstructions such as branches and leaves from the area around the condensing unit to allow sufficient airflow.

4. Remove the access panel from your outdoor condensing unit and remove the air filter from its compartment. If the air filter is dirty, brush off dirt and debris. If the air filter is really dirty, wash it in a mild detergent and water solution. Rinse the filter in clean water. Allow the filter to dry, and then reinsert it into its compartment. If your filter is worn out, purchase a replacement and replace the damaged one.

5. Check your thermostat's settings if your Nordyne air conditioner is not blowing cool air. Make sure your thermostat is set to "Cool." Lower your thermostat's temperature set point to below the room temperature displayed on your thermostat's screen. Set the fan switch to "On" or "Man." If airflow is restricted, set the fan switch back to "Auto."

6. Remove objects such as furniture, toys and drapes from the air-supply grilles in your house to allow sufficient airflow.
