How does exhaust temperature relate to performance and safety?

• A. Lower temperatures indicate efficient airflow.
• B. Temperature is not related to safety.
• C. High temperatures indicate restricted airflow and potential motor/ component strain; monitor temps.
• D. Low temperatures indicate clogged ducts.

Answer: (C)

Exhaust temperature shows how well heat is being carried away by the airflow. When the airflow is restricted—by lint buildup, a crushed or undersized duct, a long vent run, or a closed damper—the dryer keeps heating to reach its set point, but the hot air can’t exit as quickly. That causes the exhaust to rise in temperature and the internal components (like the motor and blower) to work harder, which can lead to overheating and increased wear. Over time, this is a safety concern because higher temps raise the risk of lint ignition and equipment damage. Therefore, monitoring exhaust temperature helps you spot blockages or restricted airflow early and take corrective action (cleaning, improving vent size/length, or fixing obstructions). A normal exhaust temperature is desirable; a noticeable rise is a warning sign to inspect and ensure safe operation.
