A.O. Smith 9005964005 Gas Valve

When you're out on a service call and finding that the burner won't ignite or the status light is staying dark, the A.O. Smith 9005964005 Gas Valve is your reliable replacement for residential natural gas water heaters. This White Rodgers Intellivent gas control operates on 120V and is factory-set to 4" WC manifold pressure, ensuring precise regulation for N Series and GPVT models. As a veteran-grade water heater gas valve assembly, it features a 2.25-inch shank and 1/2-inch NPT connections, making it a direct-fit solution for many A.O. Smith, State, and American water heater units manufactured after 1993. The integrated electronic thermostat provides advanced diagnostics via an LED indicator, helping you quickly identify if the issue is a tripped thermal switch or a thermopile 350mV threshold failure. Built for mechanical durability, it includes a 100% safety shutoff feature in the event of pilot failure, protecting the system and the property.

Key Benefits for Technicians:

Common Questions:

What does it mean if the status light isn't flashing?
This typically indicates an electrical issue; check the 120V power supply or press the manual reset on the thermal switch before testing the thermopile voltage.

Can this valve be used for Propane (LP) conversion?
No, this specific model is calibrated strictly for 4" WC Natural Gas and should not be used for LP applications.

Why does the pilot light go out as soon as I release the knob?
Generally, this points to the thermopile failing to generate the required 350mV to hold the electromagnetic valve open, or a disruption in the safety circuit.
