Safety first: Unplug the unit and allow it to cool completely before inspection.

• Clean airflow components: Thoroughly clean the lint filter, condenser (if removable), and any accessible air ducts.
• Check fan operation: During a drying cycle, confirm that the fan runs continuously. If not, inspect and replace the Hisense dryer fan motor as needed.
• Inspect thermostats: Access the heater housing and check the high-limit thermostat and thermal fuse for continuity. Replace any open devices with OEM parts.
• Control board concern: If the heater remains on when it should be off, the main PCB heater relay may be stuck and the board should be replaced by a professional.
