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 hot surface igniter (P/N 1171306) with matching igniter wiring kit (P/N 1188370) is the ignition source for the ICP / Tempstar / Heil RGS120LRAA0AGAA gas furnace. On every heat call the control board sends voltage to the igniter, which glows red-hot to light the burners. Hot surface igniters are brittle and fail predictably — the silicon carbide or nitride element cracks from thermal cycling, contamination from skin oils during handling, or vibration. A failed igniter is one of the most common no-heat causes. Including the wiring kit ensures a clean, corrosion-free connection so the new igniter receives full voltage and lights reliably.

Compatibility

Installation Guide

Safety First — Disconnect electrical power and verify zero voltage with a multimeter; allow the furnace to cool.
Access — Remove the burner compartment service panel.
Document — Photograph the igniter position and harness routing before removing anything.
Remove — Unplug the old igniter at the connector, remove its mounting screw, and lift it out — handle the new element only by the ceramic base, never the glow tip.
Install — Mount the new igniter, attach the new wiring kit, and route the harness clear of the burner flame path.
Test — Restore power, start a heat cycle, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement
