Overview
This OEM hot surface igniter (part 1177663) and matching igniter control board (part 1186861) handle ignition for the gas-heat section of your ICP/Heil/Tempstar WPG4604115RKA1 package unit. On a call for heat, the control board energizes the igniter, which glows white-hot and lights the burners as the gas valve opens. The igniter is a brittle silicon-carbide or silicon-nitride element that degrades with every heating cycle and eventually cracks or fails to reach ignition temperature — the single most common reason a furnace section ignites intermittently or not at all. The control board sequences the igniter, inducer, and gas valve and provides flame-sense feedback; if it fails, the igniter may never receive power. Replacing a weak igniter before it strands you during a cold snap is cheap insurance.

Installation Guide
- Safety First — Disconnect power and shut off the gas supply, then verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter bracket and all board connectors before disconnecting.
- Remove — Unplug the igniter leads and unscrew the igniter bracket; never touch the element with bare fingers. Swap the control board if included.
- Install — Mount the new igniter so it sits correctly in the burner flame path and reconnect per your photo.
- Test — Restore power and gas, then watch a full ignition cycle to confirm the igniter glows and the burners light and stay lit.
