ICP Furnace Control Board for WFML045A024A1 — OEM CEPL130438-01 | Ships Today

Overview

This OEM integrated furnace control board (OEM 1176943, board number CEPL130438-01) is the electronic brain of the ICP Tempstar/Heil WFML045A024A1 gas furnace. It sequences the entire heat cycle — energizing the inducer, proving pressure switches, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on and off. It also reads safety limits and flashes diagnostic fault codes via its LED. A failed board produces erratic, intermittent, or no-heat operation and is a common cause of hard-to-diagnose furnace faults.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the control/blower-compartment service panel.
3. Document — Photograph every connector and wire position on the board before disconnecting — terminal layout is critical.
4. Remove — Unplug each harness, remove the mounting screws/standoffs, and lift out the old board.
5. Install — Mount the new CEPL130438-01 board and reconnect every harness exactly per your photos.
6. Test — Restore power, run a full heat cycle, and confirm the diagnostic LED shows normal operation with proper ignition and blower timing.
