Furnace Ignitor Replacement Cost in 2026: What Homeowners Should Expect
Published 2026-04-03 · Reviewed 2026-08-02
See what furnace ignitor replacement costs in 2026, what drives the quote, and when a no-heat call is just an ignitor issue versus a bigger furnace problem.
A furnace that starts its sequence but does not light may have an ignitor problem, but pressure, venting, controls, gas supply, wiring, flame proving, limit or rollout safeties, and the control board can produce similar symptoms.
Key Takeaways
- Do not open the combustion compartment or handle an ignitor or flame sensor unless qualified.
- Ask what electrical or visual test confirms the ignitor fault and what other sequence checks were completed.
- OEM or model-specific part availability, access, after-hours timing, and the included combustion or safety checks affect cost.
- A one-visit repair is possible only when diagnosis is confirmed and the correct part is available; it is not guaranteed.
What a Complete Repair Scope Includes
- Startup-sequence diagnosis and confirmation of the failed ignitor or related component.
- Compatible part, careful installation, wiring inspection, and verification through a complete heating cycle.
- Combustion, venting, flame-proving, and safety checks appropriate to the furnace and diagnosed fault.
What Changes the Quote
Equipment model, OEM or approved ignitor, access, service fee, after-hours timing, related sensor or wiring work, warranty, and return visit can all change the total.
