4-wire. SL-098A W-P. Defrost Temperature Control. SNR-017
This device is an SNR-017. Defrost Temperature Control, a 4-wire bimetal thermostat assembly used in frost-free refrigerators. is typically used as a replacement part for Samsung and other compatible refrigeration brands.
Technical Specifications…
- Part Number: SNR-017 / SL-098A W-P.
- Voltage/Current Rating: Standard rating is AC 250V / 10A.
- Operating Temperature: Designed to open (cut power) at a specific setpoint, usually around 10°C to 15°C, to end the defrost cycle once the ice has melted.
- Configuration: 4-Wire Assembly featuring a white plastic connector plug. It combines a bimetal thermostat and a thermal fuse within a single waterproof sealed sleeve.
- Safety Fuse: Includes an internal thermal fuse rated at 72°C (161.6°F) to permanently cut power if the defrost heater fails to shut off, preventing damage to the appliance.
Core Function & Features
This component is a critical safety and regulatory part of the automatic defrost system:
- Defrost Termination: Mounted on the evaporator coil, the bimetal switch senses when the coil has warmed up enough to be clear of frost. It then “pops” open, shutting off the defrost heater.
- Overheat Protection: The integrated thermal fuse acts as a fail-safe. If the bimetal switch malfunctions and stays closed, the fuse will blow to prevent the refrigerator’s plastic interior from melting.
- Waterproof Design: The components are encased in a heavy-duty, moisture-proof plastic sleeve to withstand the constant condensation and ice buildup inside the freezer.
Common Failure Symptoms
If this part is faulty, your refrigerator may experience:
- Thick Frost/Ice Build-up: On the back panel of the freezer, which eventually blocks airflow.
- Warm Fridge Section: While the freezer remains cold, the fresh food section stays warm because air cannot circulate through the iced-up evaporator coils.
- Continuous Compressor Operation: The unit may run constantly to compensate for the lack of cooling efficiency.
