Fridge Thermostet PFN-124G

Description

Product Description: PFN-124G No-Frost Freezer ThermostatThe PFN-124G is a specialized electro-mechanical capillary thermostat engineered primarily for automatic defrost refrigeration setups. It features a uniquely coiled, gas-vapor filled 21cm to 25cm capillary line sensor.Because it is built explicitly for “No-Frost” (forced-air) cabinets, its capillary tube does not clamp directly to a freezing evaporator ice-plate like single-door fridges. Instead, it sits directly in the path of the cold air currents circulating through the freezer or fresh-food air ducts, breaking the main electrical contact loop precisely when the air drops to the targeted sub-zero threshold.Key Technical FeaturesModel Code: PFN-124G (frequently cross-referenced with regional variants like AWTB-124GS or VS5).Temperature Spectrum: Calibrated for heavy sub-zero air monitoring, typically executing an absolute deep cold cutout down to a range between $-24^circtext{C}$ and $-31^circtext{C}$ depending on the dial calibration.Terminal Layout: Standard 2-pin spade male termination block (plus a dedicated chassis grounding tab) for clean drop-in wiring.Control Style: Purely mechanical rotary D-shaft axle with no digital processing components.Compatible Mechanisms & AppliancesBecause it functions via physical fluid dynamics and internal mechanical springs, the PFN-124G serves as an incredibly stable universal repair standard across a massive volume of Asian and European refrigeration architectures:1. No-Frost Double-Door & Multi-Door Refrigerators (Primary OEM Match)Compatible Mechanisms: Frost-free multi-door refrigerator models across major global brands, including Daewoo (e.g., FR390, FR358, FR236 series), LG, Samsung, Toshiba, and Elba.Application: Installed right behind the main temperature adjustment housing inside the freezer compartment or the automated dampener air-duct channel. It cycles the master cooling loop based purely on forced air currents.2. Standalone Commercial Upright FreezersCompatible Mechanisms: Deep reach-in freezers, commercial catering frost-free cabinets, and specialized ice-storage vaults.Application: Ideal for setups that require deep, sub-zero preservation points where surface-contact mounting isn’t structurally feasible or ideal.3. Fixed-Speed Hermetic AC Compressors (Direct Line Control)Compatible Components: Standard single-phase 220V–240V inductive refrigeration compressors running on traditional PTC start relays or external overload protectors.Application: The heavy-duty internal contacts are built to directly break the raw high-voltage line current feeding the compressor motor without burning up. (Note: This mechanical switch cannot directly cycle or interface with modern 3-phase, variable-speed Digital Inverter compressors).4. Cross-Compatible Replacement FamiliesIn the global appliance parts supply chain, the PFN-124G serves as a direct drop-in replacement or alternative option for multiple popular configurations:Interchangeable Models: AWTB-124GS, PFN-C171, Saginomiya VS5 (PFN-124G), and matching 2-pin short-capillary air-sensing assemblies.
