If you have a high-efficiency dryer in your home or building, you may run into an issue with your dryer booster fan and new dryers not working correctly together. The sensor that triggers the booster fan to turn on may not get a signal from the lower electric use of energy efficient dryers, causing the fan to stop working altogether.
Tips on troubleshooting dryer booster fan and new dryers
- Check for Obstructions in the Ducts Sometimes, your dryer booster fan may not be working because there is an obstruction in the ducts. Check the ducts to see if there is any debris, lint, or other materials blocking the airflow. If there is an obstruction, clear it out and try turning on the fan again.
- Check the Electrical Connections Ensure that your dryer booster fan is properly connected to the electrical system. Check the breaker or fuse box to see if there is a tripped breaker or blown fuse. If the breaker or fuse is tripped or blown, reset it or replace it as needed.
- Test the Fan Motor To test the fan motor, turn off the power to the fan and remove the fan from the duct. Using a voltmeter, check the voltage at the fan motor. If there is voltage, but the motor isn’t turning, then the motor may be faulty and needs to be replaced.
- Consider Upgrading Your Booster Fan If you have an older booster fan or if your building’s booster fan system wasn’t designed to work with energy efficient dryers, you may need to upgrade your fan to a more modern and efficient model. A professional can help you determine the right fan for your needs.
