According to the Consumer Product Safety Commission Dryer Fire Report, lint plugging a dryer vent is only one of several sources of dryer fires. Failure of thermostat and limit switches inside the dryer, lint inside the dryer, a missing or damaged lint screen, and a crushed hose behind the dryer can also trigger a fire. Lint builds up more easily in longer vents, or those with curves or elbows. Empty the lint screen after every load. Frequently vacuum out area under the lint trap. It is suggested that typical vents should be cleaned every 2-3 years. If your dryer is not drying efficiently, get service to investigate the possibility of other problems that could also be a fire hazard. Call our parts department (410) 682-3232 extension 100 with the make and model number, to order a new dryer screen that can be shipped directly to you. “An ounce of protection is worth a pound of cure”!
