Hi

I have a Frigidaire washer/dryer. The dryer can take upwards to 2+ hours to dry in automatic mode.

There is heat coming from the dryer. I tried turning on the dryer and checking the vent in the dryer (where the lint trap is located). I noticed that while there is suction I do feel a small amount of air being blown BACK into the dryer.

What could cause this? The unit comes with a booster fan. Could it be the booster fan is reversed?
