This molded air tunnel directs heated air from the blower through the dryer drum for consistent airflow and efficient drying. Replaces a cracked or damaged duct to restore proper air circulation and help improve drying performance. What it does:

• Channels blower air into the drum and toward the lint screen and exhaust
• Prevents airflow loss from gaps or cracks that can reduce drying efficiency
• Helps maintain proper ventilation to reduce overheating and extended dry cycles
• Fits into the dryer's internal plenum to keep airflow focused and consistent

• One air tunnel/drying airflow duct

• Disconnect electrical power (and gas supply for gas dryers) before beginning service
• Access typically requires removing the dryer front panel or cabinet
• Align the tunnel with the blower housing and drum opening, then secure with the original fasteners or clips
• Check for a good seal around mating surfaces and reassemble panels before testing

This replacement guide secures and positions a small component or harness inside the appliance to maintain proper alignment and prevent rubbing or binding. It restores correct routing where the original guide is cracked, broken, or missing. What it does:

• Routes and holds wiring or small components to prevent chafing and interference
• Keeps parts aligned for smooth operation and proper clearance
• Prevents vibration noise caused by loose or rubbing components
• Helps maintain factory fit where a damaged guide allows movement

• Disconnect power to the appliance before beginning any repair to avoid shock or injury
• Remove only the panels and fasteners necessary to access the damaged guide; keep hardware organized
• Plastic guides can be fragile—use gentle leverage with appropriate tools to avoid breaking mounting tabs

This replacement duct directs airflow inside the appliance to help channel heat, smoke and cooking odors out of the cavity for more consistent operation and safer use. Fits where the original duct is damaged or missing. What it does:

• Channels exhaust and airflow from the appliance cavity to the vent path
• Helps reduce heat buildup that can affect cooking performance
• Prevents smoke and odors from lingering inside the unit
• Restores proper airflow when the original duct is cracked, bent or deteriorated

• Disconnect power (and gas if applicable) before starting work to avoid shock or injury
• Basic hand tools typically required; keep screws and brackets for reassembly
• Handle sharp edges carefully and wear gloves
• Follow model-specific service instructions for access and mounting
