IG418 – HOT SURFACE IGNITOR (GOODMAN, TRANE, RHEEM)

If your furnace won’t light or only clicks without igniting, the hot surface ignitor is usually the fix. This silicon carbide ignitor fits Goodman, Trane, and Rheem furnaces — one of the most common ignitor cross-references in residential HVAC.

Replaces: 767A-372, B1401015, B1401015S, B1401018, B1401018S, 62-22868-93, IGN0054, IGN0054USA, IG418

Fits: Goodman, Amana, Trane, American Standard, and Rheem furnaces using ignitor B1401015 or 767A-372.

Fits these models

• HSI hot-surface-ignition gas furnaces (most 80%+ AFUE units from 1990s onward)
• Verify voltage rating matches your existing HSI — installing the wrong voltage will burn the new one out instantly
• Bracket and connector geometry vary by OEM — bring the old part in to match

How do I test a hot surface ignitor?

Pull it out, check resistance with a multimeter across the leads. Healthy HSIs read roughly 40-90 ohms (80V) or 40-200 ohms (120V). Open circuit = dead. Bring it to the counter — we test these free.

Why does my new HSI keep failing?

HSIs fail from cycle stress and contamination. Common causes: dirty filter (overheats furnace, short-cycles), dirty flame sensor (forces re-light attempts), oversized furnace, or skin oils on the ceramic element. Fix the root cause when you replace.

How long should an HSI last?

3-7 years typical. Short-cycling burns through HSIs fast — address what's causing the short-cycling, not just the burned ignitor.
