Overview
This is a genuine OEM furnace control board (circuit board part number 1178358) paired with its ignition control module (part number 1177661) for the ICP Tempstar Heil WPG3364060RKC1 packaged gas unit. The control board is the brain of the furnace – it manages the entire ignition sequence, sequences the inducer and blower motors, monitors the limit and pressure safety switches, controls the gas valve, and provides diagnostic fault codes through an onboard LED. The ignition control module handles the hot-surface ignition timing and flame verification. When the board fails, the furnace can exhibit a wide range of faults: no response on a heat call, the inducer or blower running continuously, erratic ignition, or a flashing diagnostic code with no normal operation. Heat, voltage surges, and aged relays are the most common causes of board failure.

Compatibility
Direct-fit OEM replacement for the ICP Tempstar Heil WPG3364060RKC1 packaged gas unit. This circuit board and ignition control module are used across the ICP Tempstar, Heil, Comfortmaker, and Arcoaire WPG family. Match your existing board number (1178358) and module number (1177661) before installing, as ICP uses several board revisions.
Installation Guide
- Safety First – Disconnect power at the unit disconnect and verify zero voltage with a multimeter before opening any panel.
- Access – Remove the control/blower service panel to expose the board and ignition module.
- Document – Photograph every wire harness and terminal position on the board before disconnecting.
- Remove – Unplug the connectors and spade terminals, then unscrew the board and module from the mounting standoffs.
- Install – Mount the new 1178358 board and 1177661 module, then reconnect each harness exactly per your photo.
- Test – Restore power, start a heat call, and confirm a clean ignition sequence and a steady (no fault) diagnostic LED.
