3-wire. Defrost Temperature Control Wire : AFTC-SNR-007
The image shows an AFTC-SNR-007 Defrost Temperature Control Wire, a 3-wire bimetal defrost thermostat combined with a thermal fuse, commonly used in refrigerators to prevent ice buildup.
Core Function & Features
This component acts as a safety and regulation switch for the defrost system in “No Frost” refrigerators:
- Dual Protection: It features a bimetal disc that senses temperature to end the defrost cycle and an integrated thermal fuse that acts as a back-up safety to cut power if temperatures exceed a critical limit.
- Temperature Regulation: The bimetal typically opens the circuit at approximately
to turn off the defrost heater once the ice has melted.
- Design: The sensor is sealed within a pink-tinted moisture-proof plastic housing to protect it from the high-humidity environment of the evaporator coils.
- Wiring: It utilizes a 3-wire configuration (brown, orange, and red leads) terminated with a specialized white plastic connector plug.
Symptoms of Failure
A faulty thermostat or blown fuse will disrupt the defrost cycle, leading to:
- Heavy Frost Buildup: Ice accumulating on the back wall of the freezer or directly on the evaporator coils.
- Cooling Issues: The refrigerator or freezer section becoming too warm because air cannot circulate through the ice-blocked coils.
- Excessive Running: The compressor may run continuously as the unit struggles to reach the set temperature.
Compatibility & Supplier Details
This part is a common replacement for many major refrigerator brands, most notably LG, but it is also used in Elba, Westinghouse, and Kenmore models. It is functionally equivalent to OEM part number 6615JB2002A.📞 Contact & Procurement Details
