Overview
The Honeywell Q4100C is a silicon carbide hot surface igniter designed as a direct OEM replacement for a wide range of residential furnaces. It produces consistent resistance readings across temperature ranges and reaches ignition temperature reliably. This is the type of igniter most HVAC techs keep in their truck because it covers so many common furnace models.
Pros
- ✓ Direct OEM replacement for Lennox, Goodman, Carrier, and multiple other brands
- ✓ Consistent resistance readings across operating temperature ranges
- ✓ Silicon carbide construction handles thermal cycling well
- ✓ Packaged with ceramic gasket and mounting hardware
Cons
- ✗ Fragile during installation — handle by the ceramic body, not the element
- ✗ Higher price than generic alternatives (but more reliable)
- ✗ Not compatible with Rheem/Ruud furnaces that use a different igniter style
Who It's For
Homeowners replacing a failed igniter on a Lennox, Goodman, Carrier, or compatible furnace. Also a solid choice for HVAC techs who want one igniter that covers multiple service calls.
Who Should Skip This
Rheem and Ruud furnace owners — confirm connector style before purchasing. This igniter uses a 2-pin flat connector that differs from some older Rheem models. If you have a 30+ year old furnace, verify compatibility first.
Compatibility
Lennox (most models), Goodman (most models), Carrier/Bryant/Payne (most models), York (select models), Trane (select models), American Standard (select models)
