IFB Refrigerator COMP INV BOARD 6CC DA92-01596C NI34A SS

The IFB Refrigerator Compressor Inverter Driver Board (Part Number: RX321ECINB002 / Specification: 6CC DA92-01596C NI34A SS) is an authentic original equipment manufacturer (OEM) replacement frequency-inverter control PCB designed for select IFB frost-free and multi-door inverter refrigerators. Located in the rear compressor machinery compartment, this dedicated power board converts single-phase AC mains voltage into high-precision, variable-frequency 3-phase DC power to modulate three-phase BLDC inverter compressors. Engineered with high-efficiency Intelligent Power Modules (IPMs), high-voltage smoothing capacitors, and an extruded aluminum heat sink, it protects the compressor while optimizing energy efficiency and cycle cooling demand.

Key Features

• 6CC / NI34A Compressor Calibration: Programmed specifically to drive 6cc displacement / NI34A series variable-speed inverter compressors with optimal motor timing and torque curves.

• Integrated Intelligent Power Module (IPM): Delivers clean 3-phase sinusoidal drive output, reducing motor vibration, acoustic resonance, and overall electrical consumption.

• Heavy-Duty Aluminum Heat Sink: Rapidly dissipates thermal energy generated by high-power switching transistors during continuous cooling cycles.

• Onboard Surge & Transient Suppression: Built-in high-voltage electrolytic filter capacitors, metal oxide varistors (MOVs), and inductive chokes protect circuitry against power spikes and brownouts.

• Standardized Keyed Wire Terminals: Features keyed OEM terminal blocks for AC line input, digital PWM communication signaling from the main PCB, and 3-pin compressor motor leads (U, V, W).

Benefits

• Solves common inverter refrigerator failures such as compressor not running, continuous clicking without motor start, rapid LED diagnostic error flashes, or loss of cooling.

• Replaces burned, short-circuited, or surge-damaged inverter boards to restore original cooling operation.

• Direct OEM replacement ensures 100% frequency curve match, safe motor commutation, and factory chassis bracket mounting.

Applications

Designed specifically for select IFB frost-free inverter refrigerator models equipped with 6CC / NI34A series compressor platforms requiring inverter control board part number RX321ECINB002 (DA92-01596C).

What's Included

• 1 x Genuine IFB Refrigerator Compressor Inverter Driver Board (RX321ECINB002)

Usage Instructions

1. Disconnect the refrigerator completely from the AC mains electrical socket before starting any service work.

2. Pull the appliance away from the wall to access the lower rear machinery compartment.

3. Unscrew and remove the rear protective metal/plastic service grille.

4. Locate the separate plastic control housing mounted adjacent to the compressor that holds the inverter board.

5. Unclip the housing cover and take clear reference photographs of all wiring harnesses, grounding clips, and terminal connections.

6. Wait 5–10 minutes to allow onboard high-voltage smoothing capacitors to discharge completely before touching board terminals.

7. Unplug the AC mains input plug, the low-voltage communication harness from the main board, and the 3-wire harness running to the compressor terminals.

8. Release the board retaining clips or remove mounting screws and lift out the faulty inverter PCB.

9. Seat the new IFB RX321ECINB002 board into the casing, reconnect all wiring harnesses securely according to your reference photos, and fasten the enclosure cover.

10. Reinstall the rear machinery cover grille, reconnect electrical power, and observe compressor startup and normal cooling operation.

Safety Instructions

• High-voltage capacitors on inverter boards retain hazardous electrical charges even after mains power is disconnected. Allow adequate discharge time before handling circuitry.

• Always isolate the appliance completely from AC power before removing panels or handling internal electronics.

• Follow electrostatic discharge (ESD) safety precautions by touching a grounded metal surface before handling the bare PCB.

Care Instructions

• Keep the rear compressor area and cooling vents clear of lint, pet hair, and dust to ensure proper airflow across the inverter heat sink.
