F2557heb Parts

Defrost heater that melts frost and ice from the evaporator during the defrost cycle, helping restore proper airflow and efficient cooling. Use when frost buildup or defrost-cycle failures are causing reduced cooling performance. What it does:

• Heats the evaporator fins during the defrost cycle to remove accumulated ice and frost.
• Restores normal airflow so the refrigerator can cool evenly and avoid long run times.
• Commonly replaced when you see heavy frost buildup, poor cooling, or repeated defrost errors.
• Works as part of the defrost system alongside the defrost thermostat/timer or control board.

• Disconnect power to the appliance before testing or installing to avoid shock.
• Handle the evaporator fins carefully to avoid damage; follow OEM instructions for routing and securing the heater.

This replacement screw secures appliance panels, brackets, and components. Using the correct size restores a snug fit to reduce vibration, prevent loosening, and keep assemblies properly aligned during operation. What it does:

• Fastens sheet metal and component brackets in designated locations
• Replaces missing, stripped, or corroded hardware
• Helps eliminate rattling and vibration from loose panels
• Maintains proper alignment of covers and assemblies

• 1 screw

• Disconnect electrical power; shut off water or gas supplies if applicable
• Match length/thread to the original; replace one fastener at a time to preserve alignment
• Start by hand to avoid cross-threading; use the correct driver size
• Snug firmly but do not overtighten to prevent stripping
