SH271 - Genuine OEM Universal Refrigerator Defrost Heater Assembly

SH271 – Genuine OEM Universal Refrigerator Defrost Heater Assembly

The SH271 Genuine OEM Universal Refrigerator Defrost Heater Assembly is a replacement defrost heating component designed for refrigerator applications. This genuine OEM part helps maintain proper refrigerator and freezer performance by melting frost accumulation from the evaporator coils during the automatic defrost cycle. Available from Appliance Kingdom, this refrigerator replacement part ships across Canada with fast, reliable delivery for homeowners, landlords, property managers, and appliance repair technicians.

A properly functioning defrost heater is essential for maintaining airflow, temperature consistency, and cooling efficiency. When a defrost heater fails, frost can accumulate on the evaporator coils, restricting airflow and causing cooling problems throughout the refrigerator. Defrost heaters are specifically designed to remove frost buildup during scheduled defrost cycles, helping the appliance operate efficiently.

What Does the Refrigerator Defrost Heater Assembly Do?

The defrost heater assembly is responsible for melting frost and ice that naturally forms on the evaporator coils during normal refrigeration operation. During the automatic defrost cycle, the heater activates and removes accumulated frost before it can interfere with airflow and cooling performance.

OEM-quality defrost heaters are designed to meet exact electrical and performance specifications. Using the correct replacement heater helps ensure proper defrost operation, energy efficiency, and long-term appliance reliability.

When a defrost heater stops working, frost continues to accumulate on the evaporator coils, eventually restricting airflow and reducing cooling effectiveness throughout the refrigerator and freezer compartments.

Common Symptoms Indicating Defrost Heater Replacement

A faulty refrigerator defrost heater can cause several performance issues, including:

• Frost buildup on evaporator coils
• Excessive ice accumulation inside the freezer
• Refrigerator section becoming too warm
• Freezer section not maintaining proper temperature
• Restricted airflow from vents
• Refrigerator running longer than normal
• Uneven cooling between compartments
• Food not staying properly chilled
• Reduced energy efficiency

Replacing a failed defrost heater often resolves these symptoms when the heater has been confirmed as the source of the problem. However, similar issues may also result from a defective defrost thermostat, temperature sensor, control board, or evaporator fan motor. Proper diagnosis is recommended before replacing parts.
