The 218657301 Genuine OEM Frigidaire Refrigerator Defrost Heater is an original manufacturer replacement part designed for compatible Frigidaire refrigerators and related brands. This genuine OEM defrost heater plays a critical role in the refrigerator's automatic defrost system by melting frost and ice that accumulate on the evaporator coils during normal operation. Appliance Kingdom supplies this authentic replacement part with fast Canada-wide shipping for homeowners, landlords, and professional appliance repair technicians.

A failing defrost heater is one of the most common causes of excessive frost buildup, restricted airflow, and cooling performance issues in refrigerators. Replacing a defective heater with a genuine OEM component helps restore proper defrost operation and maintain consistent temperatures throughout the appliance.

What Does the Refrigerator Defrost Heater Do?

The defrost heater is mounted near the evaporator coils and activates during the automatic defrost cycle. Its purpose is to melt frost and ice that naturally accumulate on the coils as the refrigerator operates.

Without proper defrosting, frost buildup can restrict airflow, reduce cooling efficiency, and eventually cause temperature problems in both the refrigerator and freezer compartments. Genuine OEM specifications are important because the heater must provide the correct wattage, voltage, and heat output required by the manufacturer's defrost system design. The 218657301 heater is rated at approximately 550 watts and 115 volts.

Common Symptoms Indicating Replacement

A faulty refrigerator defrost heater may cause:

• Excessive frost or ice buildup on evaporator coils
• Refrigerator section becoming too warm
• Freezer temperatures becoming inconsistent
• Reduced airflow from freezer vents
• Refrigerator running longer than normal
• Cooling performance gradually declining
• Ice accumulation on the freezer's rear interior panel
• Frequent manual defrosting requirements

If testing confirms that the defrost heater has failed, replacing it often resolves frost-related cooling issues and restores proper automatic defrost operation. However, similar symptoms may also be caused by a faulty defrost thermostat, timer, sensor, or control board, so proper diagnosis is recommended.
