ICP Furnace Control Board for WFAR120D060A1 — OEM Part 1184783 | Ships Today

Overview

This genuine OEM integrated furnace control board (part number 1184783) is the electronic brain of the ICP / Tempstar / Heil WFAR120D060A1. It manages the entire heating sequence — energizing the inducer motor, sequencing the hot surface igniter, opening the gas valve, monitoring the flame sensor, and timing the blower on and off delays. It also runs the furnace's safety logic, locking out ignition if a pressure switch or limit trips. When the board fails, symptoms range from a completely dead furnace to erratic short-cycling, blower-only operation, or flashing diagnostic fault codes.

Specifications

Compatibility

Designed for the ICP WFAR120D060A1 and compatible Tempstar/Heil/Comfortmaker furnaces using control board 1184783. Match the board's part number and connector layout to your existing unit before installing — control boards are model-specific and not interchangeable across furnace families.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the furnace control compartment service panel.
3. Document — Photograph every wire harness and connector position before disconnecting; label any loose leads.
4. Remove — Unplug all connectors, remove the mounting screws, and lift out the old board.
5. Install — Mount the new board, transfer connectors one at a time, and reconnect each harness exactly per your photo.
6. Test — Restore power, call for heat, and verify the full ignition and blower sequence; check the LED for any fault codes.

Signs You Need a Replacement
