Williams P626766 Motor

The Williams P626766 Motor is a direct-drive 1/6 HP fan motor engineered for specific Williams console and wall furnace applications. Operating on 115V single-phase power, this PSC motor features a 1625 RPM high-speed rating with 4-speed versatility, allowing for precise airflow adjustment based on system load. The double shaft configuration is critical for dual-blower assemblies, ensuring balanced static pressure and consistent heat exchanger cooling. At an amp draw of approximately 2.1A, this motor provides efficient operation without overloading existing furnace circuits. This genuine OEM replacement motor eliminates the alignment and vibration issues commonly associated with universal alternatives. When upgrading or replacing, ensure your run capacitor is tested, as the P626766 relies on a 5 MFD/370V capacitor for optimal torque and thermal protection. For contractors, this motor serves as a drop-in solution for Williams Forbidden Heat and Grand Canyon series units requiring specific shaft lengths and diameters for wheel clearance.

Common Contractor Questions

What is the shaft diameter and length for the P626766?
This motor typically features a 1/2-inch diameter double shaft, designed to fit standard Williams centrifugal blower wheels with minimal adjustment.

Can I use this to replace a 3-speed motor?
Yes, the 4-speed lead configuration allows for greater flexibility. You will simply cap off the unused speed tap using a wire nut or terminal heat shrink.

Does this motor include the run capacitor?
The P626766 is usually sold as the motor only. It is best practice to install a new 5 MFD capacitor during replacement to ensure the motor operates within the correct LRA and FLA specs.
