Fridge Bimetal 3 Wire

Description

LG-Style 3-Wire Refrigerator Defrost Thermostat & Thermal Fuse Assembly Product Description Keep your refrigerator’s automatic defrost cycle running safely and efficiently with this premium 3-wire defrost thermostat and thermal fuse combo pack. Specifically designed to replace integrated defrost safety components, this assembly features a dual-action mechanism encased in a heavy-duty, moisture-sealed vinyl pouch to withstand the freezing, damp environment of your freezer’s evaporator coils. Unlike standard 2-wire setups, this advanced configuration houses both the bimetal thermostat and a backup 72°C inline thermal safety fuse. The bimetal monitors the coil temperature, closing to trigger the defrost heater when ice builds up, and snapping open once frost is cleared. If a system failure causes the heater to run continuously, the built-in 72°C thermal fuse acts as a fail-safe, permanently cutting power to prevent the plastic internal lining of your freezer from warping or melting. Key Features Integrated 2-in-1 Design: Features both the bimetal temperature sensor and a critical safety thermal fuse in one single pouch. Pre-Wired 3-Lead Harness: Standardized 3-wire layout (typically featuring Black, Orange, and Red leads) terminated with a precise, snap-in plastic socket connector for an airtight, plug-and-play installation. Moisture-Resistant Enclosure: Heavy vacuum-sealed casing prevents frost meltwater from corroding the internal contacts, eliminating premature part failure. Compatible Mechanisms & Appliance Brands This 3-wire component is an “Asian-type” defrost assembly engineered to work seamlessly with frost-free refrigerators that utilize a integrated safety wire loop. It is widely compatible with the following mechanisms: LG Electronics: This is a direct match for a massive variety of LG double-door, top-freezer, and side-by-side frost-free refrigerators. It replaces standard part numbers like the 6615JB2002A. Samsung: Fits select mechanical and electronic control defrost systems that route both the bimetal switch and safety fuse lines through a unified 3-wire wiring plug. Godrej & Panasonic: Directly compatible with certain double-door models designed with 3-pin wiring clips mounted near the upper evaporator tube. Universal Mechanical Defrost Timers: Works perfectly with traditional 1-3-4-2 or standard mechanical defrost timing systems configured to loop the safety fuse back to the heater circuit. 🛠️ Installation Check: Ensure your existing faulty part uses a 3-wire plug connector before ordering. If your refrigerator uses a basic 2-wire clip or an electronic 4-wire thermistor block, this 3-wire variant will not plug directly into your harness without splicing modification.
