Answer:
Preventive
Explanation:
Preventive maintenance is the maintenance that is routinely carried out on a piece of equipment to prevent it from breaking down or failing when in use. The lint trap in a dryer is used to clean out lint (textile fiber) and prevents the lints from getting into the drying vents. When the lint trap does not function well and lints get into the drying vent, the dryer may break down.
