Honeywell 40003916-036 Replacement Motor

The Honeywell 40003916-036 Replacement Motor is a high-torque synchronous motor designed for direct integration into V4044 series diverting zone valves. Operating at 120Vac, this motor provides the necessary mechanical force to actuate the valve paddle, ensuring precise flow redirection in hydronic heating and cooling systems. This specific model features 18-inch leadwires for flexible wiring within the junction box and includes a manual lever for system testing and emergency positioning. Technicians often refer to this as the V4044 replacement powerhead motor because it restores functionality to Honeywell zone valves without requiring the removal of the valve body from the piping. It is the direct replacement for the 40003916-036/U, maintaining identical electrical specifications and physical dimensions. Proper installation of this 120V synchron motor ensures reliable zone control and prevents bypass issues in multi-zone residential or light commercial hydronic applications.

Key Benefits:

• Direct Compatibility: Engineered specifically for the Honeywell V4044 Series, ensuring seamless mechanical alignment with existing valve bodies.
• Integrated Manual Lever: Allows for manual opening of the valve during system fill-ups or in the event of a power failure.
• Standardized Electrical Specs: Operates on 120V 60Hz power, making it a drop-in replacement for standard line-voltage control circuits.
• Extended Leads: The 18-inch leadwires simplify connections in crowded electrical enclosures compared to shorter 6-inch variants.
• Synchronous Operation: Provides consistent timing and torque to maximize the service life of the internal valve components.

Common Questions:

How do I troubleshoot a V4044 valve with a 40003916-036 motor?
If the thermostat calls for heat but the valve stays closed, check for 120V at the leadwires. If voltage is present and the manual lever doesn't move easily when power is applied, the replacement motor likely needs to be swapped.

Can this motor be used on V8043 valves?
No, this is a 120Vac motor. Most V8043 valves utilize 24Vac motors. Always verify the voltage requirements on the powerhead plate before installation to avoid electrical failure.

Is the 40003916-036/U a different model?
The "/U" suffix stands for "Universal" or retail packaging. The 40003916-036 and 40003916-036/U are functionally and technically identical.
