Customer Questions and Answers for Duct Assembly (Exhaust) by Lg

This duct assembly channels airflow inside the appliance to guide exhaust and internal air between components. Replacing a damaged or obstructed duct helps restore proper airflow and can reduce poor performance or long cycles. What it does:

• Directs exhaust and circulation air between internal components to maintain airflow
• Prevents leaks that can reduce efficiency or cause longer cycle times
• Helps avoid overheating or moisture build-up from restricted airflow
• Reduces rattling or vibration caused by a cracked or loose duct

• Disconnect power (and turn off gas supply for gas appliances) before beginning work.
• Handle edges carefully — sheet metal can be sharp; wear cut-resistant gloves.
• Ensure duct is seated and fastened to create a tight seal where it connects to other components.
• After reassembly, run a test cycle to confirm airflow and proper operation.
