Overview

This OEM hot surface igniter (part #1171306) is the direct-fit ignition source for the ICP / Heil / Tempstar RGS121LDCB0AAA gas furnace. When the thermostat calls for heat, the control board energizes the igniter, which glows to roughly 2,000°F and ignites the gas at the burner. This listing also includes the matching igniter wiring kit (#1188370) so the harness and connector are replaced together for a clean, reliable splice. A failed igniter is one of the most common no-heat causes — the silicon-carbide element is brittle and degrades with every heat cycle until it cracks or stops glowing. Symptoms include the furnace clicking and trying to light but never firing, short cycling on ignition lockout, or no glow visible through the sight port.

Compatibility

Engineered for the ICP/Heil/Tempstar RGS121LDCB0AAA furnace and shares the same igniter platform used across many Comfortmaker and Heil RGS-series models. Always confirm against your unit's OEM part number before installing.

Installation Guide

  1. Safety First — Disconnect power at the furnace switch and breaker; shut off the gas. Verify zero voltage with a multimeter.
  2. Access — Remove the furnace burner/service panel.
  3. Document — Photograph the igniter bracket and wire routing before disconnecting.
  4. Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter out by the ceramic base — never touch the carbide element.
  5. Install — Seat the new igniter, secure the screw, and connect using the included wiring kit per your photo.
  6. Test — Restore gas and power, then watch a full ignition cycle to confirm a steady glow and clean light-off.

Signs You Need a Replacement

  • Furnace tries to ignite but never lights, then locks out
  • No visible glow at the igniter during a heat call

How do I replace the igniter on my ICP RGS121LDCB0AAA — Direct-Fit OEM Ignitor with Wiring Kit | Ships Today?
Difficulty: Medium (20–30 min)

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.
