Resideo 40003916-046 Replacement Motor

The Resideo 40003916-046 Replacement Motor is the direct OEM synchronous motor designed for Honeywell V8044A Series Diverting Zone Valves. Operating on a 24Vac power supply, this high-torque motor ensures reliable actuation in hydronic heating and cooling systems. The unit features 18-inch leadwires for flexible wiring within tight mechanical enclosures and includes a manual lever for emergency positioning during power failures or system testing. This specific model is identical to 40003916-046/U, maintaining the exact footprint and electrical ratings required for a seamless swap-out. Contractors typically specify this motor when repairing 3-way diverting valves that exhibit sticking or failure to return to the bypass position. By replacing only the motor head rather than the entire valve body, technicians reduce labor time and avoid the need to drain the system, ensuring the V8044 zone valve repair is efficient and maintains hydraulic integrity.

Key Benefits for Contractors

• Direct OEM Compatibility: Verified for use with all V8044A series diverting valves, ensuring proper seating and torque.
• Simplifies Service: The motor can be replaced without breaking the plumbing line, significantly reducing billable hours and system downtime.
• Extended Leadwires: 18-inch factory-stripped leads provide ample length for routing to terminal blocks or transform connections.
• Manual Override: Integrated lever allows for manual operation, making it easier to troubleshoot flow issues or provide temporary heat.
• Robust Electrical Design: Purpose-built 24V synchronous motor rated for continuous duty in high-temperature hydronic environments.

Common Questions

Is the 40003916-046 compatible with V8043 series valves?
No, this motor is specifically engineered for V8044A diverting valves. V8043 series valves typically utilize the 802360JA motor; always verify the valve body model number before installation.

What causes a zone valve motor to burn out prematurely?
Premature failure is often caused by excessive ambient heat near the boiler, improper voltage supply, or mechanical binding within the valve body itself. Ensure the valve stem moves freely before installing the new motor.

Can I use this to replace a 40003916-046/U?
Yes, the 40003916-046 and the 40003916-046/U are functionally and physically identical. The "/U" suffix simply denotes a "Universal" or trade-packaged version of the same technical component.
