Fridge PCB Invertor DA9200459G

Description

Product Description: Samsung DA92-00459G Refrigerator Inverter PCB The DA92-00459G (frequently cross-referenced with factory board number H361635) is a dedicated frequency-conversion control module engineered for Samsung’s line of digital inverter refrigerators. Rather than simply switching a compressor on and off at full blast, this PCB acts as a smart power translator. It reads real-time temperature data sent from the fridge’s main computer board and dynamically modulates the electricity output frequency. This allows the cooling system to run at varying speeds—ramping up during heavy use and dialing back to a whisper-quiet, low-energy mode when the doors stay closed. Key Technical Features Module Type: Compressor Frequency Conversion Inverter Board. Component Details: Equipped with a solid-state central microcontroller, heavy power-filtering capacitors to smooth out line spikes, and a dedicated aluminum heatsink to protect the power transistors from overheating. Core Logic: Uses Pulse-Width Modulation (PWM) signal processing to handle step-less speed adjustments. Compatible Mechanisms & Appliance Components The DA92-00459G is a proprietary, closed-loop controller. It will not work with standard single-phase appliances or alternative appliance brands. It is designed to interface exclusively with the following mechanisms: 1. Samsung Digital Inverter Compressors (The Primary Load) Compatible Mechanisms: Specific Samsung BLDC or 3-Phase AC variable-speed hermetic compressors (such as the Samsung NC44 series or MSV series inverter compressors). Application: The board features a dedicated 3-pin output plug that connects directly to the compressor’s U,V, and W terminal phases. It is fundamentally incompatible with older single-phase induction compressors that rely on a mechanical PTC starter relay. 2. Samsung Main Logic Motherboards Compatible Components: Primary refrigerator motherboards (such as the DA92-00462 series or DA41-00815A blocks). Application: Connected via a low-voltage communication wire harness. The mainboard tells this inverter PCB what the internal cabin temperature sensors are reading, and this board calculates the target RPM the compressor needs to run. 3. Cross-Compatible Samsung Part Families In professional appliance repair, this exact board configuration frequently substitutes or matches parts within the same framework: Interchangeable Part Codes: DA92-00459A, DA92-00459E, DA92-00459P, DA92-00459T, and the structural PCB base DA41-00814C. 4. Target Refrigerator Models This specific inverter drive module is widely utilized across Samsung’s global lineup of No-Frost Double-Door and Top-Mount Freezer refrigerators, including: RT Series: RT25FARADSA, RT29FARADSA, RT30K3322S8, RT32K5552SL, RT35FDACDSL, and RT38K5062GL.
