This defrost heater melts frost and ice buildup on the evaporator to help restore normal airflow and consistent cooling performance. Replaces the evaporator heating element used in frost-control cycles. What it does:

• Warms the evaporator coil during defrost cycles to remove accumulated ice.
• Helps restore proper airflow when frost or ice is blocking the evaporator fins.
• Commonly used when you see heavy frost buildup, ice on the evaporator, or reduced cooling performance.
• Works with the refrigerator's defrost control/thermostat to prevent over-freezing.

• One defrost heater assembly (1 pc)

• Disconnect power to the appliance before starting any repair.
• Access typically requires removing the evaporator cover; handle panels and edges carefully.
• Replace only with the exact part number; avoid routing or pinching wires during reassembly.

• Helps prevent premature detergent release or failure to open, which can cause poor cleaning
• Restores a tight seal to keep detergent in the cup until the machine actuates the dispenser
• Fits into the dispenser assembly and operates with the existing hinge/spring mechanism

• High-level install: remove the inner door panel or dispenser assembly access to swap the flap; follow your model's service instructions
• Use proper tools and avoid forcing plastic tabs to prevent breakage
• Disconnect power before beginning service to avoid electrical hazard
• If the dispenser spring or hinge is damaged, inspect and replace those components as needed
