Fridge PCB Invertor H361635

Description

Product Description: Samsung DA92-00459G (H361635) Inverter Control Board The Samsung DA92-00459G (identifiable by the factory board printing H361635) is an original manufacturer frequency conversion power module. It acts as the direct power management controller for the refrigerator’s compressor. Rather than running an all-or-nothing cycle, this board receives low-voltage communication signals from the fridge’s main control assembly and translates them into smooth, variable-frequency three-phase power. This lets the cooling system dynamically speed up or slow down based on internal thermal load, lowering power consumption and eliminating harsh motor start-up noises. Key Technical Features Model Identification: Part code DA92-00459G paired with design identifier H361635. Circuit Architecture: Features a heavy-duty onboard capacitor block to smooth incoming AC line voltage, coupled to an aluminum heat sink designed to dissipate thermal buildup from the high-speed switching transistors. Operational Mode: Continuous closed-loop frequency regulation based on pulse-width modulation (PWM) inputs. Compatible Mechanisms & Refrigerator Components The DA92-00459G is a drop-in internal hardware component. To function without throwing error codes or causing mechanical damage, it must interface with the following exact components: 1. Specific Samsung Digital Inverter Compressors Compatible Mechanisms: Highly specific Samsung BLDC / Variable-Speed Three-Phase AC hermetic compressors (such as the NC44 or MSV series variants calibrated for the ‘G’ firmware profile). Application: The board connects directly to the compressor’s three-pin terminal cluster (U,V,W phases). It is not compatible with standard single-phase 220V compressors that rely on external start relays/PTC starters. 2. Main Logic Control Motherboards Compatible Components: Central processing mainboards from Samsung’s frost-free double-door lineup (e.g., matching DA92-00462 or DA41 series modules). Application: Connected via a dedicated low-voltage wiring harness to receive real-time cooling commands from the refrigerator’s cabinet temperature sensors. 3. Cross-Compatible Part Numbers In many repair scenarios, this board serves as a direct drop-in replacement or alternative for: Alternative Part Codes: DA92-00459A, DA92-00459E, DA92-00459P, and certain configurations of the DA41-00814B structural board. 4. Target Refrigerator Models This module is predominantly used in Samsung’s medium-to-large capacity top-mount freezer and double-door inverter models across global markets, including: RT Series: RT25FARADSA, RT30K3322S8, RT32K5552SL, and RT38K5062GL.
