My furnace will not ignite. What part is bad?

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 a genuine OEM igniter electrode, ICP part number 1179966, for the ICP / Tempstar / Heil RGS303SDFA0AAAA gas furnace. The electrode delivers the high-voltage spark that ignites the gas at the burner during the ignition sequence; on many ICP designs the same electrode assembly also senses flame to confirm a successful light. A cracked ceramic insulator, eroded tip, or carbon-fouled electrode prevents reliable ignition — the furnace will lock out after several failed trials, short-cycle, or fail to produce heat at all. Replacing a worn electrode restores fast, consistent light-off.

Is this igniter compatible with Bryant or Payne too?

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.
