Msc 18-4 Parts

This lower door air shield directs airflow and protects internal door components from steam and moisture. Replacing a cracked or missing shield helps restore proper airflow and prevents steam from contacting sensitive parts inside the door. What it does:

• Guides exhaust airflow and helps maintain proper drying and ventilation paths inside the lower door
• Shields controls, insulation, and wiring from direct steam and moisture exposure
• Reduces rattles or vibration caused by a loose or damaged inner door panel
• Common signs you need this part: visible cracks or deformation, door interior moisture/steam contact, or loose paneling

• Disconnect power to the appliance before beginning any repair
• Remove the lower door panel/panels to access the shield; save and reuse existing screws
• Handle edges carefully; sheet-metal parts can be sharp
• Secure all fasteners; test a full cycle to confirm fit and function
