My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Is this igniter compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM vs. Generic

Our genuine Goodman OEM ignitor is precision-matched to the exact resistance and mounting geometry of your furnace, ensuring correct surface temperature and long service life. Universal generic ignitors may require adapter brackets, splice kits, and can fail prematurely due to voltage mismatch. For a plug-and-play repair that lasts, OEM is the safe choice.

Installation Difficulty

Easy (2/5). A basic repair for a handy homeowner — power off the furnace, unplug the old ignitor connector, remove one or two mounting screws, and reverse. Handle the fragile element by the ceramic base only. Allow 15–20 minutes.
