Dryer takes forever or gets very hot

The short answer

Long drying times or a hot dryer usually mean a clogged lint screen or vent duct. That is a fire risk: clean the lint screen every load and get the duct cleaned. Failure to clean is the leading factor in home dryer fires.

Burning smell or smokeStop the dryer. Smoke or flame: get out and call 911.
