The WZDK20-38G motor by IXGPUTS is a compact, brushless DC fan motor designed for central and inverter air conditioning systems. It operates at DC280V and 20W with a current of 0.10A, delivering reliable airflow. Its size is approximately 92x111mm, and it runs at 1300 RPM in a CCW rotation. This model is suitable for Midea inverter indoor units, making it a practical replacement for compatible WZDK38G variants.
Key features include a robust build for OEM compatibility and a two-year warranty, offering assurance for installations that demand consistent performance. The CCW rotation aligns with many OEM configurations, reducing installation adjustments. Consider this option if you’re replacing a 20W motor in a Midea-based inverter system that requires DC280V operation with similar dimensions.
New Air Conditioning Motor WZDK30-38G (RD-310-30-8T) DC Brushless Fan Motor
The WZDK30-38G motor from IXGPUTS targets 30W inverter air conditioner systems. With a DC310V rating and 0.14A current draw, this motor runs at 1300 RPM in a CCW direction and fits Midea inverter indoor units. The motor’s size is 92x129mm, matching many OEM footprints. It includes a two-year warranty, which helps offset replacement uncertainty in critical cooling components.
This model is well-suited for higher-load applications within Midea inverter setups, especially where a 30W motor is recommended. Prospective buyers should verify mechanical fit, including shaft diameter (8mm) and the CCW rotation, to ensure compatibility with existing housings and fan blades.
D1092 RV Air Conditioner Fan Motor With Capacitor
The D1092 motor from SEAHEE is a direct replacement option for RV air conditioning systems. It features a 1/3 HP rating, 115V operation, and a high-speed 1675 RPM, which supports efficient air movement in mobile units. Two-speed operation adds versatility for varying cooling demands. A new 7.5 MFD capacitor is provided to support proper starting torque and consistent startup behavior.
Compatibility includes certain Coleman, Carrier, and Bryant/Payne models; however, users should confirm exact cross-reference numbers and mounting configurations before purchase. The included capacitor is a convenient upgrade for older systems that require a modern, reliable power supply. This motor is a practical choice for replacing aging RV fan assemblies with attention to electrical compatibility and wiring configurations.
Air Conditioner Motor FN20V-ZL (ZWK428A000013)
FN20V-ZL is a DC310V brushless motor designed for GREE central air conditioning indoor units. It delivers 20W of power and 1400 RPM in CCW rotation, with an 8mm shaft diameter. The motor sizing, 92x121mm, makes it suitable for a range of GREE-branded inverter systems. A three-year warranty is included, which reflects confidence in durability and long-term performance.
Users should confirm the exact model fit with their GREE unit, as OEM variants can differ in mounting patterns and electrical connectors. The motor’s 310V DC rating is compatible with inverter-type configurations, offering efficient operation and reduced energy consumption when paired with the right drive electronics.
Air Conditioning DC Brushless Fan Motor ZKFP-20-8-6-7
Brand new DC brushless fan motor with a 20W rating, DC280V input, and 1300 RPM CCW rotation. The motor targets WZDK20-38G and RD-280-20-8 family configurations, with a shaft diameter of 1/4 inch and a compact footprint suitable for Midea inverter indoor units. It is designed for quick replacement and ease of installation, helping restore airflow and cooling performance for affected systems.
Air Conditioner Indoor Motor WZDK20-38G (ZKFP-20-8-6) 20W
Generic brand option; this indoor motor supports the same WZDK20-38G family and 20W power class. It emphasizes compatibility with Midea inverter air conditioners, delivering dependable CCW rotation and a 92x111mm form factor. While it provides a cost-effective replacement, verify the shaft diameter and mounting pattern to ensure a proper fit within the existing fan housing and electrical connector layout.
Buying Guide: Key Purchase Considerations
- Motor type and compatibility: Brushless DC motors (BLDC) are common in modern inverter units, offering higher efficiency and longer life than brushed motors. Check the exact model compatibility (WZDK20-38G, FN20V-ZL, etc.) and ensure the rotation direction (CCW) matches your system’s original configuration.
- Voltage and power rating: Match motor voltage (DC280V, DC310V, DC310V, etc.) and power (20W, 30W) to your unit’s control circuit and airflow requirements. Incorrect voltage can cause motor failure or suboptimal cooling.
- Physical dimensions and shaft details: Note motor size (in mm), shaft diameter (8mm, 1/4″, etc.), and mounting pattern. A precise fit reduces installation time and eliminates vibration or misalignment.
- Warranty and cross-compatibility: A longer warranty (2–3 years) suggests better reliability. If replacing multiple OEM parts, confirm cross-reference compatibility to avoid mismatches that require additional adapters.
- Capacitor and accessories: Some motors ship with a capacitor or require one for proper startup. Ensure the included capacitor matches your system’s requirements or plan for a compatible capacitor upgrade.
- Application type: Determine whether the motor is intended for central air, inverter indoor units, or RV/portable applications. RV motors may differ in mounting and electrical interfaces from residential central-air motors.
- Manufacturer and regional availability: Popular brands like IXGPUTS and ACROTOR offer broader support, but confirm regional shipping and warranty coverage for your locale.
- Energy efficiency and noise: Modern BLDC motors typically deliver better efficiency and quieter operation. If noise is a concern, verify decibel ratings or user reviews for the specific model.
When selecting a replacement, compile system specifics (unit model, voltage, RPM, shaft size) and compare against the candidates above. Prioritize compatibility and warranty to ensure reliable cooling performance and a smooth installation experience.
