The Goodman B1401012 Hot Surface Ignitor is a genuine OEM ignition component for the Goodman GDT070-3A gas furnace and compatible models. On each call for heat the furnace control energizes this igniter, which glows red-hot to light the burner gas. A cracked, worn, or open igniter is the single most common cause of intermittent or complete no-heat furnace failures. Installing the correct OEM ignitor restores fast, reliable ignition and eliminates repeated ignition-lockout faults.

Specifications

Part number: B1401012
Type: Hot surface ignitor (HSI)
Brand: Goodman (OEM)
Application: GDT070-3A and compatible Goodman gas furnaces
Function: Direct-replacement burner ignition
Includes: Ignitor with mounting bracket and lead connector

OEM vs. Generic

The OEM Goodman B1401012 uses Goodman's factory element material, bracket, and plug so it drops in without adapters and matches the control board's timing and resistance expectations. Universal silicon-nitride igniters can work and are more shock-resistant, but they require verifying connector type and mounting fit. For a guaranteed match we recommend the OEM ignitor; handle any igniter only by the ceramic base — skin oils shorten element life.

Installation Difficulty

Easy (2 of 5). Cut power at the disconnect, unplug the igniter lead, remove the one or two mounting screws, and set the new ignitor without touching the element. Reconnect and test for a clean glow and light-off. About 15 minutes.
