Nordyne Intertherm 624619 24V Hot Surface Ignition Step Opening Gas Valve 1/2 Inch Inlet Straight Outlet with 3/8 Inch Right-side Outlet

Product Description

The Nordyne Intertherm 624619 is a 24-volt hot surface ignition gas valve designed for use in Nordyne, Intertherm, and Miller brand furnaces and heating systems. This valve features a step opening design, which means it opens in stages rather than all at once. Step opening reduces the risk of combustion bursts and helps the burner light more smoothly and safely. HVAC technicians trust this design in residential and light commercial heating equipment where controlled gas delivery is critical.

The 624619 has a 1/2 inch inlet and a 1/2 inch straight outlet, making it compatible with standard gas supply lines used in most residential furnace installations. It also includes a 3/8 inch right-side outlet, giving installers added flexibility when routing gas lines in tight equipment cabinets. This dual-outlet configuration makes the valve well suited for multi-stage burner assemblies or systems that require a secondary gas feed point.

This valve operates on 24 volts, the standard control voltage used in most residential HVAC systems. It is designed to work with hot surface ignition systems, which use a ceramic igniter to light the gas rather than a standing pilot flame. Hot surface ignition is more reliable and energy efficient than older pilot light systems, and it is now the dominant ignition method in modern gas furnaces.

HVAC service technicians use the 624619 as a direct replacement part during furnace repairs. When a gas valve fails, the furnace will not fire, leaving the home without heat. Installing the correct OEM-spec replacement valve restores proper gas flow, pressure regulation, and ignition sequencing. This part is built to meet the specifications of the original equipment, helping ensure a reliable repair that meets safety standards.
