Fridge Thermostet GNF-110

Description

Product Description: GNF-110 Frost-Free Refrigerator ThermostatThe GNF-110 (frequently cross-referenced with LG part numbers 6930JB1003D or 6930JB1006F) is an electro-mechanical air-sensing thermostat. It features a specialized fluid-filled capillary tube sensor probe. Because it is engineered for automatic defrost (frost-free) refrigerators, the capillary tube is short and reads the temperature of the circulating cold air current passing through the cabinet rather than being clamped to a freezing ice plate.When the internal air reaches the designated cold threshold, the internal bellows contract to break the main electrical contacts, pausing the compressor. It operates reliably on standard 125V/250V AC power lines, handling an electrical rating of roughly 8A / 5A to manage inductive compressor startup cycles.Key Technical FeaturesPart Numbers: GNF-110, 6930JB1003D, 6930JB1006F, and EBG61306301.Temperature Spectrum: Calibrated for frost-free operations, typically managing an air-sensing range from roughly $+9^circtext{C}$ down to $-9^circtext{C}$ or lower depending on dial calibration.Terminal Layout: Standard 2-pin spade male configuration (plus a grounding tab).Control Type: Mechanical rotary D-shaft axle with no digital processing components.Compatible Mechanisms & AppliancesThe GNF-110 is a widely utilized replacement standard in multi-compartment refrigerators that use a fan to distribute air:1. LG & Westinghouse Frost-Free Double-Door Refrigerators (Primary OEM Match)Compatible Mechanisms: Conventional No-Frost 2-door refrigerators (such as the LG GR-252SF, GR-332SF, GR-372SF, and GN-205SQA series).Application: Installed inside the air duct control assembly of the fresh food compartment or freezer section. It measures the forced air moving through the vents to cycle the cooling system efficiently.2. Multi-Brand No-Frost Refrigerator CabinetsCompatible Mechanisms: Frost-free models from brands like Sharp, Samsung, Sanyo, and Daewoo that utilize a mechanical cold control dial.Application: Serves as a highly reliable universal replacement part for dual-door setups where the thermostat needs to track air currents rather than direct surface frost.3. Fixed-Speed Hermetic AC Compressors (Direct Line Interruption)Compatible Components: Standard single-phase 220V–240V inductive refrigeration compressors using an external PTC start relay.Application: The internal heavy-duty contacts break the high-voltage live line powering the compressor directly. (Note: This mechanical switch cannot be used to directly interface with or cycle modern 3-phase, variable-speed Digital Inverter compressors).4. Direct Replacement Component FamiliesIn the global appliance repair trade, the GNF-110 is widely cross-compatible with or replaces the following architectures:Interchangeable Models: PFN-C171, GNF-120, and matching Saginomiya or Aruki air-sensing dual-door thermostat profiles.
