Fire Marshal Michael Reed Asst.
Some fires can occur when lint builds up in the filter or in the exhaust duct.
Under certain conditions, when lint blocks the flow of air, excessive heat build-up can cause a fire in some dryers. Clean the lint filter regularly 2. Check that the outside exhaust is allowing air to escape normally. If not, turn off and remove any lint found. If the dryer is operating hotter then normal, have the thermostat checked professionally.
