What Is the Nidec GW10C12MS2BA-52 Refrigerator Cooling Fan?

The Nidec GW10C12MS2BA-52 is a compact DC brushless cooling fan purpose-built for Haier refrigerator evaporator and condenser compartments. Manufactured by Nidec Corporation (Japan), a global leader in precision motors, this fan operates on 12V DC drawing just 0.11A (1.32W), making it an energy-efficient component in the refrigerator's thermal management system. Its small form factor is engineered to fit within the tight confines of a refrigerator's internal ductwork, circulating cold air from the evaporator coil throughout the fresh-food and freezer compartments. The fan's brushless DC motor design ensures low electrical noise (critical to avoid interference with the refrigerator's control board), long bearing life in cold and condensing-humidity environments, and quiet operation at the low RPM typically used in domestic appliances.

In short: A genuine-spec 12V DC Nidec built-in cooling fan for Haier refrigerators -- the correct replacement when your fridge compartment is not cooling evenly or the evaporator fan has become noisy. Supplied new by koeed.com.

Technical Specifications

Before replacing a refrigerator fan, unplug the appliance and discharge any capacitors on the control board. Refrigerator fan connectors are often keyed and polarized -- do not force the plug. If the old fan shows signs of ice buildup, check the defrost system before installing the replacement, or the new fan may suffer the same fate.

Typical Symptoms of a Failed Evaporator Fan

• Uneven cooling: Freezer section stays cold but fresh-food compartment warms up, indicating the evaporator fan is not circulating cold air between compartments
• Loud humming or rattling: Worn fan bearings produce noise that changes pitch as the fan speed varies with the cooling cycle
• Fan not spinning: The fan blade is stationary even when the compressor is running; may be accompanied by a faint buzzing from the stalled motor
• Intermittent operation: Fan starts and stops unpredictably due to a failing Hall sensor or worn brushless driver electronics inside the fan motor
• Ice accumulation: Excess frost on the evaporator cover near the fan opening suggests poor airflow due to a slow or stopped fan

Frequently Asked Questions

How do I confirm this fan matches my Haier refrigerator model?

Check the label on your existing fan -- the model number GW10C12MS2BA-52 is typically printed on a sticker on the fan hub or frame. You can also cross-reference your refrigerator's full model number (found on the rating plate inside the fridge compartment) with Haier's parts catalog. If the existing fan has a different Nidec part number, contact KOEED with both numbers and we can verify interchangeability.

Can I use a generic 12V fan instead of the Nidec original?

Not recommended. Refrigerator evaporator fans operate in a condensing humidity environment with temperature swings from below freezing (defrost cycle) to ambient. Generic fans may lack the sealed bearing design, moisture-resistant PCB coating, and specific RPM/airflow curve that the Nidec unit was engineered to deliver. An incorrect fan can produce inadequate airflow (leading to warm spots), excessive noise, or premature failure due to moisture ingress. The Nidec GW10C12MS2BA-52 is the specified replacement for Haier refrigerators.

Does this fan include the mounting bracket and connector?

The fan is supplied as the motor-and-blade assembly with its integral wiring pigtail and connector. The mounting bracket or shroud is typically part of the refrigerator's internal ductwork and is reused from the old fan. Keep all screws, rubber isolation grommets, and the mounting bracket when removing the old fan -- you will need them for the new installation.

The old fan was noisy. Will this new one be quiet?

Yes -- a new Nidec fan should be nearly silent in operation, producing only a soft air-movement sound. The brushless DC motor is inherently quieter than shaded-pole AC fan motors used in older appliances. If the new fan is also noisy, check that the mounting screws are not overtightened (which can distort the frame and cause blade rub), that no ice is contacting the blade, and that the fan blade is not striking any wiring or foam insulation inside the duct.

Is this fan compatible with other refrigerator brands besides Haier?

The GW10C12MS2BA-52 was designed for specific Haier refrigerator models. While it may physically fit other brands that use 12V DC brushless fans with the same mounting pattern and connector, the RPM and airflow characteristics were tuned for Haier's evaporator design. Using it in a different brand's refrigerator may result in suboptimal cooling performance. Always cross-reference your appliance's service manual for the correct replacement part number.
