Robertshaw Z-94406-6 Coil Assembly

The Robertshaw Z-94406-6 Coil Assembly is a mission-critical 120V AC solenoid coil engineered for high-performance fluid and gas management. Specifically designed to integrate with Robertshaw FJ and FJT controls, this electromagnetic component provides the necessary field strength to actuate valves and contactors in demanding industrial and commercial HVAC systems. This replacement coil assembly ensures precise modulation of gas flow and refrigeration cycles by reacting instantly to control logic signals from thermostats or ignition modules. Built with high-grade copper windings and professional-grade encapsulation, the Z-94406-6 handles thermal stress efficiently, making it a reliable choice for veterans in the field looking to restore system integrity. Whether you are servicing a gas solenoid valve with a 3/8" FPT connection or maintaining complex 120 volt HVAC controls, this coil offers the exact electrical characteristics—typically measuring between 1.5 and 1.7 ohms of resistance—required to meet original equipment manufacturer specifications without compromising performance.

• Direct OEM Compatibility: Specifically designed for Robertshaw FJ and FJT Series gas valves, ensuring a drop-in fit.
• Optimized Electrical Efficiency: The 120V coil assembly is tuned to provide consistent electromagnetic force while minimizing energy consumption.
• Contractor-Grade Durability: Robust construction protects internal windings from humidity and vibration common in furnace and refrigeration environments.
• Precision Actuation: Provides reliable switching for compressors, pumps, and gas solenoid valves to maintain tight system tolerances.

How do I verify if the Z-94406-6 coil is defective?
Using a multimeter set to ohms, test the resistance across the outer terminals; a healthy operator head coil typically reads between 1.5 and 1.7 ohms. An "OL" or infinite reading indicates an open winding that requires immediate replacement.

Can this 120V coil be used on 24V gas valves?
No. Using a 120V AC coil on a low-voltage circuit will fail to actuate the valve, while applying 120V to a 24V valve will lead to immediate component failure and potential fire hazards. Always verify the voltage rating on the control chassis.

Does this assembly include the valve body?
No, this is the replacement solenoid coil only. It is designed to slide over the existing plunger tube of your compatible Robertshaw gas valve or control assembly.
