ICP Hot Surface Igniter Kit for WFMR070A024B3 — HSI with Bracket | Ships Today

Overview

This is a genuine OEM hot surface igniter assembly for the ICP / Tempstar / Heil model WFMR070A024B3 gas furnace. The kit centers on igniter part 1176919, with mounting bracket 1183455 and the associated HSI snap hardware (1176929). The hot surface igniter glows orange when the control board energizes it, lighting the burners at the start of each heating cycle. Because it operates at extreme temperatures and cycles thousands of times per season, the igniter is one of the most common furnace wear parts. A cracked or worn igniter is the leading cause of no-heat calls: the inducer runs, the gas valve attempts to open, but the burners never light and the furnace locks out.

Specifications

Compatibility

Designed as the factory replacement for ICP, Tempstar, Heil, Comfortmaker, and Arcoaire furnaces in the WFMR series, this igniter assembly is a direct fit for model WFMR070A024B3 and matches the original 120V hot surface ignition system.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, bracket orientation, and wire routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; handle only by the ceramic base, never the silicon nitride element.
5. Install — Mount the new igniter and bracket, align it to the burner port, and reconnect per your photo.
6. Test — Restore power and watch a full ignition cycle to confirm the burners light.
