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

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