Lint collecting around the dryer door seal is a sign of a clogged or obstructed dryer vent. An obstructed dryer vent leaves lint that would normally pass through with nowhere to go. When lint is unable to be properly expelled through your dryer vent, the fan pushes it into the door seal. When this happens, excess lint can be seen collecting along the edges of the seal.
What happens when lint collects around my dryer door? Lint that collects around the door seal, or the source of the problem – the vent clog – can ignite and start a dryer fire. Clogged dryer vents are not only a major fire hazard, but also make your dryer more expensive to operate.
