Overview
This genuine ICP furnace control board (OEM circuit board 1178358 with ignition control module 1177661) is the brain of your ICP / Tempstar / Heil WPG3304060LKC1 package gas-electric unit. It sequences the entire heating cycle — energizing the inducer, proving the pressure switch, firing the hot-surface igniter, opening the gas valve, monitoring the flame sensor, and timing the blower on and off. It also manages safety lockouts and flashes diagnostic fault codes through its onboard LED. When the board fails you may see no ignition at all, an inducer that runs but never lights the burners, intermittent no-heat calls, a blower that won't shut off, or a board with no LED activity. Burned relay contacts, scorched traces near the gas-valve terminals, and cracked solder joints are all clear signs the board has reached end of life.

- Access — Remove the blower/control service panel to expose the control board and its harness.
- Document — Photograph every plug, wire color, and terminal position before disconnecting anything.
- Remove — Unplug the wiring harnesses, release the mounting standoffs or screws, and lift out the failed board.
- Install — Seat the new board on its standoffs and reconnect each harness exactly per your photo.
- Test — Restore power, start a heat call, and confirm a full ignition sequence with no fault codes and correct blower timing.
