The vent pipe is only 12" long, goes straight out the wall. It blows fine, however, it seems to surge a little bit. I put my hand up the vent on the dryer and nothing. I stuck my fridge lint brush down in the lint trap hole and nothing. I open the door up and it seems to be really hot in there. She tells me the washer spin cycle is working fine that the clothes have all the water out of them, and they are caked to the side of the washer. But she keeps complaining that she has to turn the dryer on for two cycles per load now.
