Why does my SystemAir Fantech DEDPV-705 Fan LED flash 3 times then pause?
If the LED on your SystemAir Fan flashes three times followed by a brief pause, it indicates that the system airflow has been reduced. It's recommended to speak with a professional to inspect and clean the exhaust system. If this is new construction, the duct layout might be too restrictive, so inspect the duct layout, referring to sections 3.1.1 and 3.1.2.
What to do if SystemAir Fantech DEDPV-705 works but the LED doesn't light up?
If your SystemAir Fan is working but the LED is not illuminated, the low voltage wire may not be correctly plugged into the product; ensure it is properly connected. Also, check the low voltage connection to the indicator panel to ensure the wire polarity is correct, with red connected to positive and black to negative.
What does it mean when the SystemAir Fantech DEDPV-705 Fan LED flashes twice with a pause?
If the LED on your SystemAir Fan flashes twice, followed by a brief pause, it means the product is working at less than its standard speed. Check the product for any buildup of debris or motor damage, and remove any buildup if found.
How to fix intermittent LED flashing on a SystemAir Fan?
If the LED on your SystemAir Fan flashes intermittently when the dryer is on, it indicates a locked rotor condition. Inspect the product for any buildup of debris or motor damage. If there is buildup, remove it.
What to do if SystemAir Fantech DEDPV-705 Fan LED flashes after the dryer stops?
If the LED on your SystemAir Fan flashes after the dryer stops, it indicates decreased airflow through the duct system, and no further action is needed.
What to do if the SystemAir Fantech DEDPV-705 Fan LED doesn't light up and it's not working?
If the LED on your SystemAir Fan isn't illuminating and the unit isn't working, several issues could be the cause. First, ensure the fan is properly connected to a 120V AC power source. Check for blockages in the duct between the dryer and the fan, and remove any obstructions. Inspect the clear plastic tubing for damage like moisture or cracks, and replace it if needed. Verify the tubing is correctly connected between the nipple on the fan and the dryer duct, consulting section 3.2.5 if needed. Also, check the wire polarity of the low voltage connection to the indicator panel (red to positive, black to negative). Finally, if the safety thermal fuse has opened, the product needs replacement, and you should consult the dryer manufacturer about the exhaust temperature exceeding 196° Fahrenhei...
The Fantech DEDPV-705 Dryer Exhaust Duct Power Ventilator is a specialized product designed to enhance the performance of residential dryers (both gas and electric) by overcoming performance loss caused by long or restrictive duct systems. Unlike general dryer boosters, the DEDPV-705 is engineered to comply with strict safety requirements, making it a crucial component for safe and efficient dryer operation. Operating a dryer without a functional DEDPV-705 can lead to unsatisfactory drying, increased energy consumption, and potentially a dryer fire.
The DEDPV-705 works in conjunction with the dryer to ensure proper exhaust airflow. It is designed to be installed within the dryer's exhaust duct system, providing additional power to move air through long or complex duct runs. The device includes a pressure switch that monitors the airflow within the duct. If the dryer is operating and the product senses positive pressure within the exhaust duct, it will activate to assist in expelling air. This intelligent operation ensures that the dryer's exhaust system maintains optimal performance, preventing lint buildup and reducing the risk of fire. The system also features an indicator panel with an LED light that visually alerts the user to any malfunctions, such as blockages, wiring issues, or thermal fuse activation.
