This thaw heater is the evaporator defrost heating element that melts frost during the refrigerator's defrost cycle. Replacing a failed heater helps restore normal defrosting and reduce frost buildup that can restrict cooling. What it does:

• Heats the evaporator coil during the defrost cycle to melt accumulated ice
• Prevents excessive frost buildup that can block airflow and reduce cooling efficiency
• Common symptoms of a failing heater: heavy frost or ice on the evaporator/back wall, reduced cooling, or long compressor run times
• Works as part of the appliance's defrost system alongside the defrost thermostat and control

• Disconnect power to the appliance before starting any repair
• Access typically requires removing interior panels and the evaporator cover; handle the evaporator and wiring carefully
• Inspect associated defrost components (thermostat, timer/control) if problems persist; replace only parts confirmed faulty

This cover protects and tidies the refrigerator water line area, keeping hoses routed and partially shielded for a cleaner look and reduced snag risk. It's a simple trim piece used where water lines exit or run along the cabinet. What it does

• Conceals and organizes exposed refrigerator water lines for a neater appearance
• Helps prevent hoses from catching or rubbing against other components
• Restores missing or damaged trim that leaves water lines exposed
• Works with factory routing to maintain intended hose positioning

• One water line cover/trim piece

• Disconnect power and shut off the water supply before starting work
• Access may require moving the refrigerator away from the wall or removing a rear/top trim panel
• Typically secures with clips or screws—retain hardware from the original part if possible

Fix ice buildup on evaporator coils with this defrost thermostat. Monitors coil temperature to signal defrost cycles. Test for continuity when frozen.
