Jvm1190wy003 Parts

This upper duct directs airflow inside the appliance to help vent steam and cooking vapors away from internal components. It replaces a damaged or warped duct to restore proper airflow routing and reduce moisture buildup. What it does:

• Channels exhaust and airflow through the appliance cabinet for proper venting
• Prevents contact between internal components and redirected steam or grease
• Helps reduce moisture accumulation that can lead to odors or component corrosion
• Fits into the upper duct assembly location to maintain designed airflow paths

• One upper duct (upper B) as shown

• Disconnect power to the appliance before beginning any service
• Handle the duct carefully to avoid bending or cracking mounting tabs during installation
• Verify alignment with adjacent duct pieces and secure all fasteners; test airflow operation after reassembly
