Lennox 74W71 Manifold 322838-753 Reduced Maintenance: Arcing is minimized

Reduced Maintenance: Arcing is minimized by high-purity contacts

specifically when dealing with 120VAC power supplies and probe-based sensing protocols

this thermal expansion valve includes the integrated sensing bulb and capillary tube for accurate pressure-temperature feedback

It serves as a drop-in replacement for legacy models including BG1100MAAK-1G

This heavy-duty control is built to withstand high-vibration environments

Lennox 74W71 Manifold 322838-753 Reduced Maintenance: Arcing is minimizedThe Lennox 74W71 Gas Manifold (OEM part 103087 02) is a precision engineered component designed for high efficiency fuel distribution in Lennox gas furnaces and select commercial rooftop units. As a direct fit HVAC replacement part, it ensures balanced gas flow to the burner assembly, mitigating pressure fluctuations that cause combustion instability and resonance noise. Constructed from aluminized steel, this manifold resists the high heat corrosion
