Dryer runs but takes very long to dry clothes; laundry is still damp after a full cycle.

Safety first: Turn off and unplug the dryer before deep cleaning.

• Clean lint filter: Remove lint after every cycle; wash the filter with warm water and mild detergent if it appears coated.
• Clean condenser (if applicable): Remove and rinse the condenser under running water until clear; allow to drain and dry.
• Check exhaust duct (vented models):
  • Disconnect the hose from the back of the dryer.
  • Remove lint and debris from the hose and wall vent.
  • Straighten any kinks or crushed sections.
• Clean moisture sensor bars: Wipe the metal bars inside the drum with a cloth and vinegar to remove residues that can affect sensing.
• Load and program: Avoid overloading and select an appropriate dryness level; test with a medium load.

Note: If drying remains poor after thorough cleaning, the heater or heat pump system may require professional diagnosis.
