When was the last time you checked the lint filter? On most dryers, the filter is on top of the door or down the bottom on the frame. Open the plastic cover and remove all lint stuck to it. It is vital to do it after each single use to prevent it from clogging and causing damages to your dryer’s main parts. If it has a tear, you must replace it immediately before any further use to prevent the lint to get inside the dryer and eventually cause a dramatic fire.
