The Goodman B1401018S Hot Surface Ignitor is a genuine OEM igniter for the GMPN100-4 gas furnace and other compatible Goodman and Amana units. The hot surface ignitor (HSI) heats to a glowing temperature when energized, lighting the burners at the start of each heating cycle. It is one of the most common furnace failure points — a no-heat call is very often a cracked or burned-out ignitor. Replacing it with the correct OEM part restores fast, dependable startups all winter long.

Specifications

OEM Part Number: B1401018S
Voltage: 120V
Type: Hot surface ignitor (HSI)
Compatible Model: GMPN100-4 (and select Goodman/Amana furnaces)
Equipment: Gas furnace
Brand: Goodman (OEM)

OEM vs. Generic

Universal ignitor kits require adapting brackets and connectors and often use a different element material with a shorter lifespan. The genuine OEM B1401018S arrives with the exact mounting bracket, gasket, and plug so it drops straight in and matches your furnace control board's timing profile. Because the ignitor element is fragile, buying the correct factory part avoids repeat failures and callbacks.

Installation Difficulty

Moderate (2/5). Swapping the ignitor is a quick job — disconnect power, unplug the harness, remove one or two screws, and install the new unit. Never touch the ceramic element with bare fingers, as skin oils shorten its life. Shut off gas and 120V power before servicing. DIY-capable owners can handle this, but a technician is recommended if you are unsure.

Order the genuine Goodman B1401018S hot surface ignitor for a perfect fit and reliable ignition.
