4-wire, N15-4 / 8115, Defrost Temperature Control : AFTC-SNR-016
This device is an AFTC-SNR-016 Defrost Temperature Control, a 4-wire bimetal thermostat assembly used in frost-free refrigerators. is commonly used as a replacement part for LG, Kenmore, and other major refrigeration brands.
Core Specifications
- Part Number: AFTC-SNR-016 / N15-4 / 8115.
- Voltage/Current Rating: Typically rated for AC 250V / 10A.
- Operating Temperature: The bimetal switch is generally set to open (cut power) at approximately 15°C (59°F), which ensures the defrost heater shuts off once the ice has melted from the evaporator coils.
- Safety Fuse: Includes an integrated thermal safety fuse (the secondary component inside the sleeve) rated at 72°C (161.6°F) to permanently cut power if the heater fails to shut off.
- Configuration: 4-Wire Assembly with a specialized blue plastic connector plug for secure installation.
Key Functionality
This component is a critical safety and efficiency regulator in the refrigerator’s defrost system:
- Defrost Regulation: Mounted on the evaporator coil, it monitors the temperature during a defrost cycle. When it senses the coil is warm enough that ice is gone, it “pops” open to stop the heater.
- Overheat Prevention: The integrated thermal fuse acts as a backstop. If the primary bimetal switch fails to open, the fuse will blow to prevent the refrigerator’s plastic interior from melting or catching fire.
- Moisture Protection: Both the bimetal and the fuse are sealed in a heavy-duty waterproof plastic sleeve to prevent moisture and ice from causing electrical shorts.
Common Failure Symptoms
If this part is faulty, you may notice:
- Ice Buildup: A thick layer of frost on the freezer’s back panel, blocking airflow.
- Cooling Issues: The refrigerator section stays warm while the freezer is cold (due to blocked air vents).
- Clicking Noises: A repetitive clicking sound coming from the freezer area during the defrost cycle.📞 Contact & Procurement DetailsTo secure pricing, check stock availability, or coordinate bulk fulfillment across Saudi Arabia, contact the Ayub First Trading Company distribution offices directly:
