The Goodman B1401014 is a genuine OEM hot surface igniter for the DMP150-52AA gas furnace. On each call for heat, the control board energizes the igniter until it glows red-hot, lighting the burners. Because the ceramic element is brittle and wears with every cycle, the igniter is one of the most common furnace failure points — a furnace that clicks and calls for heat but never lights usually needs this part.
The genuine B1401014 provides the correct resistance, glow temperature, and mounting geometry for reliable, repeatable ignition. Generic igniters often have mismatched resistance that shortens element life or causes ignition-lockout faults. OEM delivers the longest, most dependable service life.
Moderate (2/5). Remove one or two mounting screws, unplug the connector, and install the new igniter — handling only by the base, never the ceramic tip (skin oils shorten its life). Kill power at the breaker before servicing.
