Troubleshooting
If you encounter issues with your Suncourt Equalizer EZ8 HC600-WK, refer to the following common solutions:
Fan Not Turning On

- Verify HVAC Operation: In automatic mode, the fan only operates when your HVAC system is actively heating or cooling. Confirm your furnace or air conditioner is running.
- Adjust Sensitivity: The fan uses a thermocouple to sense airflow. If the fan is not activating reliably, adjust the sensitivity dial on the unit.
Insufficient Airflow
- Increase Fan Speed: Adjust the fan speed dial to a higher setting. The fan has 8 adjustable speeds.
- Clear Obstructions: Ensure the register and the fan's intake/output grilles are free from dust, debris, or other obstructions.
- Proper Fit: Verify the fan is correctly positioned over the vent opening, allowing for optimal air capture.
Excessive Noise
- Reduce Fan Speed: Lowering the fan speed will decrease operational noise.
- Check for Vibrations: Ensure the fan is stable and not vibrating against the register or floor. The unit includes fan isolators to minimize vibration.
- Internal Components: The fan assembly is designed for quiet operation. If unusual noises persist, ensure no foreign objects are interfering with the fan blades.
