  If the Fantech Fan's LED isn't lighting up when your clothes dryer is running, there are several things to check: * First, ensure the booster fan is working correctly. * Verify the booster fan is properly connected to a 120V AC power source. * Make sure there are no blockages in the duct between the dryer and the booster fan. * Confirm the clear plastic tubing is properly connected between the booster fan's nipple and the dryer duct. * Check that the low voltage wire is securely plugged into the booster fan. * Finally, check the polarity of the low voltage connection to the indicator panel (red to positive, black to negative); the LED won't light up if the polarity is reversed.
