Fridge Bimetal 4 Wire

Description

Product Description: LG No-Frost Refrigerator 4-Wire Defrost Thermostat Bimetal Assembly Restore the automated frost-regulation cycle to your cooling appliance with this premium 4-Wire Refrigerator Defrost Thermostat Bimetal Assembly (commonly matching OEM specifications like the 6615JB2003J series). Specifically designed for no-frost freezer configurations, this assembly combines a highly sensitive bimetal temperature switch and an integrated safety thermal fuse sealed inside a moisture-proof, heavy-duty vinyl casing. This vital safety component senses when the evaporator coils drop below freezing to initiate the defrost heater, melting away accumulated ice. The 4-wire layout features a pre-installed blue connector socket/jack to ensure a sealed, plug-and-play connection that resists the high-humidity, sub-zero conditions inside the freezer compartment. Key Features Dual-Component Protection: Houses both the automatic bimetal defrost thermostat switch (-7°C / 19.4°F trigger) and a backup thermal safety fuse to prevent the freezer from overheating. 4-Wire Integrated Harness: Features color-coded leads terminating in a specialized blue snap-in connector jack, eliminating the need for manual wire cutting or splicing. Moisture-Proof Encapsulation: The entire internal circuit is completely sealed against frost accumulation, preventing premature shorts or electrical failures. Standard Electrical Rating: Optimized for standard domestic refrigeration grids, rated up to 15A at 125VAC or 7.5A at 250VAC. Compatible Brands & Model Series This 4-wire bimetal thermostat assembly is widely utilized across double-door, side-by-side, and bottom-mount no-frost refrigerator models. It is heavily compatible with: 1. LG Refrigerators (Primary Fitment) This is an industry-standard replacement part specifically tailored for LG Double Door Refrigerator Defrost Systems. It functions as a direct drop-in replacement across various global LG series, including: LG GR-Series: Highly compatible with mid-to-large capacity frost-free models (e.g., GR-3321W, GR-T366, GR-T332, and GR-M562 configurations). LG Express Cool & No-Frost Lineups: Fits standard overhead freezer compartments utilizing a 4-pin blue socket wiring layout. 2. Universal & Cross-Brand Compatibility Due to its standardized -7°C temperature threshold and safety parameters, this 4-wire configuration can be adapted or spliced into alternative frost-free cooling systems, including: Samsung Refrigerators: Compatible with select older-generation frost-free configurations requiring a combined bimetal and thermal fuse setup. Elba & Toshiba Refrigerators: Fits various top-mount double-door models that employ matching 4-wire harness schematics. Godrej & Panasonic Units: Serves as a reliable alternative service replacement part for technicians looking to restore factory-spec defrost timing. ⚠️ Safety Note: Always unplug your refrigerator from the mains power supply before servicing. This component must be physically clipped or zip-tied directly against the evaporator coil tube to accurately read the freezing temperature and function correctly.
