Williams P626763 Motor

The Williams P626763 is a heavy-duty 115V 1Ph 1/15HP 1100RPM 4 Speed Motor engineered for precise performance in residential and commercial HVAC units. As the direct replacement for P623674, this specialized blower motor ensures seamless mechanical integration without requiring bracket modifications in most standard Williams furnace configurations. Operating at 1/15 HP with a maximum speed of 1100 RPM, this unit supports 4-speed adjustability, allowing technicians to fine-tune system airflow to meet specific static pressure requirements or occupant comfort levels. The single-phase design is optimized for 60Hz electrical systems and comes with a pre-wired capacitor to streamline field installation. This OEM-spec Williams motor also serves as a critical upgrade for obsolete P623666 units, though technicians replacing that older model should verify if the M100582 mount is required for the specific cabinet layout to maintain proper alignment and vibration dampening.

• Universal Compatibility: Serves as the factory-authorized direct replacement for P623674 and obsolete P623666 models.
• Multi-Speed Versatility: Features a 4-speed motor design, providing flexibility for varied heating and cooling load demands.
• Standard Electrical Specs: Runs on common 115V single-phase power, making it a drop-in solution for most standard Williams fan coil units and furnaces.
• Optimized Performance: Delivers high-torque 1100 RPM operation to ensure consistent CFM output across the ductwork.

Is this motor compatible with older Williams furnace models?
Yes, the P626763 is the current replacement for P623674. If you are replacing the older P623666 motor, check your current mounting bracket as the M100582 mount may be necessary for a secure fit.

What is the benefit of the 4-speed configuration over a single-speed motor?
The 4-speed adjustability allows you to optimize the blower's speed based on the specific resistance of your system's ducting, reducing noise and improving overall energy efficiency during cycle operation.

Does this motor include the necessary capacitor for installation?
This 115V HVAC motor typically ships with the required capacitor to ensure the starting torque meets OEM specifications for 1/15 HP workloads.
