Are your clothes taking forever to dry? It could be lint buildup in your exterior dryer vent.
It’s one of the biggest reasons why dryers fail. Cleaning a dryer vent can be easy. First unplug the dryer from gas and electric hookups, and turn off the gas if necessary. Then disconnect the pipe and run a dryer vent brush through it (or even use your vacuum hose) to banish that lint. After this, head outside and make sure some critter hasn’t taken up residence in the nice, warm pipe. While you’re cleaning the vent, check its color. If it’s white, you need to replace it with aluminum. The white vents can catch fire.
