The Goodman B2526002 4-Cell Gas Manifold is a genuine OEM replacement engineered specifically for the Goodman GMP100-3 gas furnace. The manifold is the backbone of your furnace's combustion system — it carries pressurized gas from the valve and distributes it evenly across all four burner ports, ensuring a stable, efficient flame and clean ignition every cycle. A cracked, corroded, or mis-drilled manifold leads to uneven burn, delayed ignition, and safety lockouts, so replacing it with an exact-match OEM part restores factory performance.

Specifications

Configuration: 4-cell (4-port) manifold
Fuel: Natural gas (orifice-matched)
Fits: Goodman GMP100-3 furnace
Material: Steel with factory-set orifice spacing
OEM Part Number: B2526002

OEM vs. Generic

This is a genuine Goodman OEM manifold — port spacing, thread pitch, and orifice bore are guaranteed to match your GMP100-3. Generic manifolds often require re-drilling or shimming and can throw off gas pressure calibration. For a combustion component, exact OEM fit is the safe choice.

Install Difficulty

Moderate — requires shutting off gas, disconnecting the gas valve, and re-checking manifold pressure with a manometer after install. Recommended for HVAC technicians or experienced DIYers. Always leak-test connections before restoring service.
