- Allow the motor to cool down for at least 15-30 minutes before attempting to use again.
- Check for any visible obstructions or blockages around the air vents and blades.
Clean and Clear Airflow Pathways

Avoid blending excessively large batches or using the blender continuously for long periods. Use the preset blending programs designed for specific tasks, such as smoothies or hot soups, to prevent motor strain. Allow the blender to rest between heavy use sessions.
