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 (ignitor electrode, part #1179966) is the direct ignition component for your ICP Tempstar Heil RGS243LTAA0AAAA gas furnace. On a call for heat, the furnace control energizes this igniter, heating its element until it glows hot enough to light the burner gas. Because the element is brittle and stressed on every heating cycle, it is one of the most common furnace failure points. Typical failure symptoms include no ignition, a furnace that clicks but never lights, a cracked or broken igniter, and a system that locks out after several failed ignition attempts.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter.
Access — Remove the furnace burner-compartment service panel.
Document — Photograph the igniter wiring and mounting orientation before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s); handle only by the ceramic base, never the fragile element.

Test — Restore gas and power, then run a heat cycle to confirm the igniter glows and the burners light.

Is this igniter compatible with Bryant or Payne too?

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.
