Overview
This is the genuine OEM integrated furnace control board kit (part number 1183618) for the ICP/Tempstar/Heil RGS150LFAA0AAAA gas furnace. The control board is the brain of the furnace: it manages the ignition sequence, monitors the pressure switch and limit safeties, sequences the inducer and blower motors, and times the heat and cool cycles. Because it sits in a hot, vibration-prone environment, the board's relays and solder joints can fail over time, producing intermittent or total loss of heating and cooling. This kit ships with the mounting hardware and instructions needed for a direct factory replacement.

Installation Guide
- Safety First - Disconnect electric power and gas, then verify zero voltage at the board with a multimeter.
- Access - Remove the furnace control-compartment service panel.
- Document - Photograph every wire harness and terminal on the old board before disconnecting.
- Remove - Unplug each connector, remove the mounting screws, and lift out the failed board.
- Install - Mount the new board, transfer each connector to the matching terminal exactly per your photo, and set any jumpers or DIP switches to match.
- Test - Restore power and gas, run a full heat and cool cycle, and confirm correct ignition, blower, and fault-code operation.
Signs You Need a Replacement
- No response from the furnace - no inducer, igniter, or blower on a call for heat.
- Intermittent operation or random shutdowns mid-cycle.
- Diagnostic LED flashes a hard fault or no light at all with power applied.
- Visible burn marks, scorched relays, or corroded traces on the old board.
