A:Answer Thank you for your inquiry! If your Insignia™ 6.7 Cu. Ft. Electric Dryer with Sensor Dry is taking nearly three hours to dry a load of towels, several factors could be at play. One common reason is lint buildup, either in the lint filter or the exhaust vent, which can restrict airflow and reduce drying efficiency. Make sure to clean the lint trap before every load and inspect the vent hose for any blockages or kinks. Another possibility is the sensor dry function—if the moisture sensors inside the drum are dirty or malfunctioning, the dryer may not detect dryness accurately and continue running longer than necessary. Additionally, towels are dense and absorbent, so they naturally take longer to dry, especially if the dryer is overloaded. Using the wrong drying cycle, such as a low heat or eco mode, can also extend drying time. For towels, it's best to use a high heat setting like “Heavy Duty” or “Very Dry.” Lastly, ensure that the dryer is receiving the proper 240V electrical supply and that the ventilation system is efficient and unobstructed. If all these areas check out and the issue persists, it may be time to contact Insignia support or a technician for further inspection.
