Nordyne 903596 Gas Valve

The Nordyne 903596 Gas Valve is a technical-grade furnace gas valve replacement designed specifically for hot surface ignition systems in mobile home and residential HVAC units. Operating on a standard 24v gas valve circuit, this component features a 1/2" inlet and a 3/8" outlet, providing precise manifold pressure regulation at 3.5" W.C. for Natural Gas and 10" W.C. for Liquid Propane. As a veteran-verified solution, the Nordyne 903596 serves as the direct OEM replacement gas valve for obsolete models, including 624490, 624610, 624619, and 624619R. This unit is compatible with various Intertherm and Miller M1 series furnaces, ensuring the reliable gas flow and safe combustion timing required by professional contractors. The valve is field-convertible, allowing technicians to toggle between fuel types by adjusting the regulator screw to meet specific site requirements.

• Universal Compatibility: Engineered as a drop-in replacement for Honeywell VR8205R2091 and Robertshaw 7200DERC valves.
• Dual-Fuel Versatility: Fully rated for both Natural Gas and LP applications with adjustable pressure settings.
• Precise Ignition Control: Optimized for 24VAC hot surface ignition (HSI) sequences to prevent delayed ignition or lockouts.
• Installation Ready: Often includes the necessary mounting bracket and flange to secure the valve against the burner plate.
• Compact Footprint: Standard 1/2" x 3/8" configuration fits tight furnace vestibules without requiring extensive manifold modification.

Is the Nordyne 903596 compatible with standing pilot furnaces?
No, this valve is designed strictly for intermittent ignition or hot surface ignition systems. It does not have the pilot output required for older standing pilot units.

How do I convert this valve from Natural Gas to LP?
Technicians can convert the unit by flipping the regulator screw or using the included conversion kit components to shift the discharge pressure to 10" W.C. for propane.

What are the symptoms of a failing Nordyne gas valve?
Common indicators include the HSI glowing without ignition, 24V signal present at the terminals without the internal solenoid clicking, or inconsistent manifold pressure leading to flame rollout.
