Overview
This OEM hot surface igniter (OEM part numbers 1186861 and 1177663) is the ignition component for the ICP / Tempstar / Heil WPG4244060RKA1 packaged gas/electric unit. When the thermostat calls for heat, the integrated control board energizes the igniter, which glows red-hot to light the gas at the burners. A failed igniter is the single most common cause of "no heat" on these units. Igniters are consumable wear parts — repeated heating and cooling cycles eventually crack the silicon-nitride or silicon-carbide element, breaking the circuit. Symptoms include the inducer running but no flame, a furnace that clicks and tries but never lights, or a unit that locks out after three failed ignition attempts.

Installation Guide
- Safety First — Disconnect power at the unit disconnect and shut off the gas supply. Verify zero voltage with a multimeter.
- Access — Remove the unit's control/burner access panel.
- Document — Photograph the igniter bracket position and wiring before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter out. Handle only by the ceramic base — never touch the fragile element.
- Install — Mount the new igniter in the exact bracket position, reconnect the plug, and confirm the element sits in the burner flame path.
- Test — Restore gas and power, initiate a heat call, and verify the igniter glows and lights all burners cleanly.
Signs You Need a Replacement
- Inducer runs but burners never ignite (no glow).
- Furnace locks out after multiple ignition attempts.
- Visible cracks, hot spots, or white/gray flaking on the element.
- Intermittent heat that returns after a reset but fails again.
