ICP Furnace Control Board for WFEL070B036A1 — OEM Board 1187101 | Ships Today

Overview

This OEM integrated furnace control board (part 1187101) is the electronic brain of the ICP Tempstar/Heil WFEL070B036A1 gas furnace. It manages the entire heating sequence — inducer start, pressure-switch proving, hot surface igniter warm-up, gas valve timing, flame sensing, and blower on/off delays — while monitoring safety circuits and storing diagnostic fault codes on its LED. When the board fails, the furnace may short-cycle, fail to ignite, run the blower continuously, or go completely dead. It supplies 120V switching to the inducer and igniter and 24V to the gas valve and thermostat circuit.

Specifications

Compatibility

Built for the ICP Tempstar/Heil WFEL070B036A1 gas furnace and shared ICP-family platforms using the 1187101 control. Verify the printed part number on your existing board before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the blower-compartment service panel.
3. Document — Photograph every wire and connector on the old board before removing anything.
4. Remove — Unplug the harness connectors, release the board mounting tabs/screws, and lift out the failed board.
5. Install — Mount the new 1187101 board, transfer each connector to the matching terminal exactly per your photos, and confirm the thermostat and limit wiring.
6. Test — Restore power, run a heat call, and verify the full ignition sequence and blower operation. Check the LED for steady-on (normal) versus a flashing fault code.

Signs You Need a Replacement

• Furnace is completely dead with no LED light on the board.
• Short-cycling or random shutdowns mid-heat-call.
• Blower runs nonstop or never engages.
