768A-842 – HOT SURFACE IGNITOR (80V, AMANA, 11111701S)

If your furnace won’t light or only clicks without igniting, the hot surface ignitor is usually the fix. This 80V silicon nitride ignitor is a direct replacement for Amana furnaces using part 11111701S. Make sure your furnace uses an 80V ignitor — not 120V — before purchasing.

Replaces: 11111701S, 768A-842, 768A-2

Fits: Amana gas furnaces using 80V ignitor 11111701S.

Fits these models

• Amana 80% AFUE gas furnaces, GUD / GMS / GME series (~1990s-2010s)
• Goodman GMS80, GMS8 80% AFUE series (same Amana/Goodman family)
• Most Amana / Goodman 80% AFUE single-stage gas furnaces from that era
• Verify your existing ignitor is 80V — some Amana use 120V HSI instead (different part)

How do I test a hot surface ignitor?

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

80V vs 120V — what do I have?

The voltage is printed on the data plate inside the furnace and often on the control board. Or look at the existing ignitor — 80V Amana use a specific 2-pin Amana plug; 120V universals usually have a different connector.

How many cycles will an HSI last?

3-7 years typical. Short-cycling — caused by a dirty filter, an oversized furnace, or a dirty flame sensor — burns through HSIs fast. Address the underlying cause when you replace.
