Whether you have a gas or electric clothes dryer, you should clean the venting system at least once a year. This prevents lint and other debris from becoming trapped, which reduces operating efficiency and can contribute to dryer fires.
You will need:
Step 1: Remove the lint trap from the dryer and empty it. Hold it under running tap water and if the water does not flow through the holes in the screen, clean the screen with soapy water and a scrub brush, then rinse it.
Step 2: Unplug the dryer and shut off the gas supply for a gas dryer.
Step 3: Remove the vent cap located on the exterior of the home. Cut away any caulk with a utility knife and use the screwdriver to remove all screws. If the vent has a sleeve, slide this out. Wash the sleeve and vent cap in soapy water, rinse, and dry. Vacuum lint from the portion of the vent attached to the home. Reattach the sleeve and vent cap.
Step 4: If your dryer vents to the roof and you can access the area, vacuum debris from this vent.
Step 5: Pull the dryer out approximately 1 ½ to 2 feet from the wall. With a nut driver or screwdriver, loosen the vent clamp on the back of the appliance. Remove the vent tubing from the dryer.
Step 6: Remove lint and other debris from the hole located on the back of your dryer. Use a vacuum and reach in as far as possible.
Step 7: Vacuum the vent tubing that was removed in Step 5, removing lint and other debris.
Step 8: Most lint builds up within a foot of the end of the dryer hole. However, if you discover lint buildup in the middle of the venting system, a plumber snake, vacuum cleaner wand, dowel, or coat hanger can be used to remove it.
Step 9: Put the vent clamp back on the dryer hole, reattach the tubing, tighten the clamp with the nut driver or screwdriver, and put the dryer back into place.
Step 10: Turn on the gas supply and plug the appliance into an electric outlet.
Step 11: Adjust the controls to the air fluff setting and run this cycle for 10 minutes to remove loosened debris.
