Why does my Dryer have a Booster Fan?
In the past, dryer vents that exceeded 35ft would usually require an inline booster fan to assist in pushing out the dryer’s moist air. Sometimes during construction these booster fans are installed improperly and may need to be inspected. The lint from the dryer also passes through the fan and if not regularly cleaned the fans motor can burn out.
As of recent, the IRC no longer allows the use of booster fans.
Many times, we will suggest removing these fans if the dryer is capable of pushing the required length.
