Washer-dryer combo does not dry clothes; clothes remain wet and cold after drying cycle.

Safety first: Unplug the appliance and allow time for internal parts to cool.

Step-by-step checks:

• Clean lint and airflow paths: Remove lint from the lint filter, blower housing, and internal ducts. Poor airflow can cause overheating and blown fuses.
• Test thermal fuse and thermostats: Access the dryer heater housing and check continuity of the thermal fuse and thermostats. Replace any open component.
• Test dryer element: Measure resistance across the heater. Replace if open.

When to replace: Replace the dryer heating element or thermal fuse as needed. If all components are good but there is still no heat, the main control board’s heater relay may be faulty.
