IG401 – HOT SURFACE IGNITOR (AMANA)
Hot surface ignitors are fragile — never touch the silicon carbide element with your bare fingers. Skin oils cause hot-spot failures later. Hold the new one by the bracket only. And if you've been turning the furnace on and off trying to diagnose, you've shortened the new one's life every cycle.

If your furnace won’t light or only clicks without igniting, the hot surface ignitor is usually the fix. This silicon carbide ignitor is a direct replacement for Amana furnaces using part 767A-369 or D9918202A.
Replaces: 767A-369, D9918202A, 201A, 41-401, IG401
Fits: Amana gas furnaces using ignitor 767A-369 or D9918202A.

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.
