ICP Hot Surface Igniter for WFMR070A036A1 — Furnace Ignition | Ships Today

Overview

This OEM hot surface igniter (part number 1176919, IGNITER) is the factory ignition element for the ICP/Heil/Tempstar WFMR070A036A1 gas furnace, and pairs with valve/snap-disc kit 1176929 in the same ignition assembly. The hot surface igniter glows orange-hot when energized by the control board, lighting the burners at the start of each heating cycle. Because the igniter is repeatedly heated and cooled, the element becomes brittle and eventually cracks — the single most common no-heat failure on modern furnaces. A failed igniter produces no glow, an ignition lockout after several trial attempts, or a furnace that clicks and runs the inducer but never lights the burners.

Specifications

Compatibility

Fits the ICP/Heil/Tempstar/Comfortmaker WFMR070A036A1 furnace and related WFMR-series furnaces using this igniter and the 1176929 snap-disc/valve assembly. Confirm the igniter mounting and connector style against your existing part before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and shut off the gas; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; handle the old element by its ceramic base only.
5. Install — Mount the new igniter — never touch the element with bare fingers — and reconnect the lead per your photo.
6. Test — Restore power and gas, then confirm the igniter glows and the burners light cleanly.
