• Helps prevent restricted airflow, warm spots, and long run times
• Common failure symptoms include heavy frost on the evaporator, poor cooling, ice buildup on the back panel, or frequent defrost errors
• May cause sizzling sounds or water under the evaporator area during normal operation after replacement

• Unplug the refrigerator before service; defrost any heavy ice to access parts safely
• Access typically from the rear of the freezer compartment behind the evaporator cover
• Handle heater leads and evaporator fins carefully to avoid damage
• Secure all connectors before reassembly
