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 OEM igniter electrode, ICP part number 1179966, is the ignition source for your RGS300HDFA0AAAA gas furnace. On a call for heat, the control board energizes the igniter so it glows or sparks to light the burner gas, then the flame sensor confirms ignition. Igniters are fragile and degrade with every heating cycle — the element grows brittle, develops hairline cracks, and eventually fails to reach ignition temperature or breaks entirely. A failed igniter is the single most common reason a gas furnace stops producing heat: the inducer and gas sequence may begin, but with no ignition the furnace locks out after a few attempts. Because igniters are inexpensive and wear-prone, many technicians replace them proactively during seasonal service to prevent a no-heat call on the coldest night.

Installation Guide

Safety First — Disconnect power at the switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
Access — Remove the burner compartment door to reach the igniter at the burner assembly.
Document — Photograph the igniter's mounting position and wire routing before disconnecting.
Remove — Unplug the igniter harness, remove the mounting screw(s), and carefully lift out the old igniter. Handle only by the ceramic base — never touch the element.
Install — Position the new igniter without touching the element, secure the screws, and reconnect the harness per your photo.
Test — Restore gas and power, call for heat, and watch the igniter glow and the burners light cleanly through a full cycle.
