If your clothes dryer feels really hot, but your clothes take forever to dry, the vent may be clogged. A clogged vent traps the excess hot air inside the dryer’s drum. But the low circulation of air keeps clothes from getting dry. This is a big problem — the extra heat can damage fabrics and can start a fire — but it’s nothing you can’t fix yourself.
1. Start by checking the vent flap or hood on the outside of the house. Make sure that you feel a strong flow of air coming out when the dryer is running. If not, try cleaning out the vent with a straightened clothes hanger.
2. If the vent flap is not the problem, check for a kink or sag in the duct and straighten the hose if necessary.
3. If a kinked or sagging duct is not the problem, disconnect the duct from the dryer and look for blockage inside with a flashlight. To remove the blockage, shake it out or run a wadded cloth through the duct. If the duct is damaged, replace it.
