IGN00152 – HOT SURFACE IGNITOR (TRANE, AFTERMARKET, DIRECT, SSN087KS)

If your furnace won’t light or only clicks without igniting, the hot surface ignitor is usually the fix. This 120V silicon nitride ignitor is a direct replacement for Trane and American Standard furnaces using IGN00152 or IGN00146.

Replaces: IGN00152, IGN00146, IGN0152, IGN0146, IGN152, IGN146, IGN-110-101, D156805, SSN087KS

Fits: Trane: TUD2C100B9V5VB, TUD2C100B9V5VBB; and other Trane/American Standard furnaces.

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.
