DA92-00459E PCB

Description

Product Description: Samsung DA92-00459E Refrigerator Inverter PCB Control Board The Samsung DA92-00459E is an original manufacturer (OEM) or high-grade replacement Frequency Conversion Inverter Board. Instead of turning a compressor entirely ON or OFF like traditional fridges, this board takes digital instructions from the refrigerator’s main motherboard and translates them into variable-frequency AC power. By precisely modulating the electrical cycles, it allows the compressor to run slower or faster based on internal food temperatures, drastically lowering energy consumption, minimizing operational noise, and extending the lifespan of the cooling system. Key Technical Features Functionality: Variable-frequency inverter drive module (Frequency Conversion Board). Part Numbers & Alternates: Interchangeable or highly compatible with Samsung part codes DA92-00459A, DA92-00459P, DA92-00459T, DA92-00459Y, and motherboard numbers DA41-00814B / DA41-00814C. Circuit Safety: Features an onboard aluminum heatsink to dissipate thermal load from the heavy-duty power transistors, along with integrated surge-protection capacitors. Compatible Mechanisms & Refrigerator Models The DA92-00459E is an internal appliance component. It is strictly compatible with Samsung Digital Inverter Compressors and specific double-door/frost-free refrigerator models. It interfaces directly with the following mechanisms and systems: 1. Samsung Digital Inverter Compressors (Mandatory Load) Compatible Mechanisms: Variable-speed BLDC/Three-Phase AC scroll or piston compressors used by Samsung (such as specific NC44 or MSV series inverter compressor models). Application: The 3-pin output terminal block on this PCB connects directly to the compressor’s hermetic terminals (U,V,W phases) to control its mechanical pumping speed. It is completely incompatible with standard single-phase, fixed-speed induction compressors. 2. Samsung Main Logic Motherboards Compatible Mechanisms: Primary refrigerator control boards (e.g., DA92-00462 series or DA41-00815A blocks). Application: This inverter board receives low-voltage pulse-width modulation (PWM) square-wave signals from the main control motherboard to know exactly what RPM the compressor needs to target. 3. Specific Samsung Refrigerator Models This board is widely deployed across Samsung’s global line of double-door and top-mount frost-free refrigerators, including: RT Series: RT25FARADSA, RT32K5552SL, RT38K5062GL, RT38FEACDSL, RT43K6271SL, and RT53H6670SL. Alternative Regional Variants: Local double-door inverter models like the RT37K5532UT and RT47K6231BS. 4. Internal Cooling Fan Mechanisms Compatible Components: 12V DC Evaporator and Condenser brushless fan motors. Application: In many layouts, the power delivery timing of this board coordinates with the system’s fans to ensure that when the compressor ramps up to maximum speed, the forced-air cooling fans speed up accordingly to maintain ideal cabinet temperatures.
