A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

This is the OEM ignitor electrode (part number 1179966) for the ICP / Tempstar / Heil RGS303HTEA0AAAA gas furnace. The ignitor electrode produces the high-voltage spark that lights the main burner on each heating call. When this component degrades, the furnace will fail to ignite, short-cycle on ignition lockout, or produce repeated clicking without flame. The electrode tip and ceramic insulator are precision-formed to maintain the correct spark gap and dielectric isolation, ensuring reliable, repeatable ignition through thousands of heating cycles.

My furnace won’t ignite. What part is bad?

Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.

Is this igniter compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP igniter?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
