Dryer takes too long to dry or never reaches the selected dryness level; no error code.

Safety first: Unplug the dryer before deep cleaning.

Airflow and condenser cleaning:

• Clean the lint filter thoroughly, including washing with warm soapy water to remove fabric softener residue.
• Remove and rinse the condenser/heat exchanger under running water until clean; allow to drain and dry.
• Vacuum lint from accessible ducts and the fan housing.

Moisture sensor cleaning:

• Locate the metal moisture sensor bars inside the drum and scrub them with a non-abrasive pad and vinegar to remove residue.

Run a test load with a moderate amount of laundry. If dry times are still excessive, the heating system or heat pump may be underperforming and should be checked by a technician.
