UcarSoon Refrigerator Power Circuit Board Replacement 628661 — N-Series 2006–2019, Nano Waterproof Coating

UcarSoon 628661 is a direct-fit replacement power circuit board kit designed to restore control and protection to compatible RV and residential refrigerators from select 2006–2019 model families.

This replacement board kit replaces the factory 628661 module and includes a nano waterproof coating to help shield the exposed external control panel from moisture. It’s intended for models across multiple series (N41x, N51x, N6x, N8x, NX/NXA, N1095 and select 1200/1210/1211 models) produced from 2006 through 2019. The part restores electrical control of key cooling components and is shaped to match single-row connector layouts used on later production refrigerators.

Will this board fit my refrigerator model?

Compatibility depends on the model family and manufacturing year. This board matches single-row connector designs introduced after 2006 across the listed series; pre-2006 refrigerators that use two-row 8-pin plug connectors are not compatible.

• Fits: N410, N412, N510, N512 and other N41X/N51X variants
• Also fits: N6X, N8X, NX/NXA, N1095, and select 1200/1210/1211 models (2006–2019)
• Does not fit: pre-2006 units with two-row 8-pin plugs

How does the nano waterproof coating help in outdoor installations?

The coating forms a clear, thin molecular film on the board that resists moisture and light precipitation. It’s especially useful because the control panel is often located on the exterior of RVs where rain, snow, and humidity can reach circuitry.

• Creates a transparent water-repellent layer over components
• Helps prevent shorting caused by mist, rain, and condensation
• Reduces corrosion risk on exposed solder joints and traces

What functions will this replacement restore?

Once installed, the board re-establishes the refrigerator’s electronic control for cooling sequences and protection features. It ensures the system can manage power delivery and maintain the intended operational logic for compressors, igniters, and other cooling components.

• Restores control signals to cooling components and safety circuits
• Helps ensure normal operation of refrigeration cycles
• Interfaces with existing wiring harnesses on compatible models

Are there installation or compatibility cautions I should know?

Check the connector style and year before ordering: this replacement uses a single-row pin layout common on later models. If your refrigerator predates 2006 and uses two-row 8-pin connectors, this kit won’t mate correctly and will not work without modification.

• Verify year and model number against the supported series list
• Confirm the board connector is single-row, not two-row 8-pin
• Professional installation is recommended if you’re not experienced with appliance electronics

Who is this for: this power circuit board kit is intended for RV owners, repair technicians, and DIYers who need an OEM-equivalent 628661 replacement for compatible 2006–2019 models. It’s a practical choice when the original control board shows moisture-related failures, intermittent operation, or complete loss of electronic control. If you have an older unit with a different connector arrangement, check your refrigerator’s connector configuration and model year first to avoid ordering the wrong part.
