Rheem47-ICM284 – Furnace Control Board

The ICM284 control is microprocessor based using software to determine the sequence of operation, timing, trial for ignition, flame sensing and lockout. The control monitors the status of the room thermostat, limit and rollout switches, air pressure switch and flame sensor before energizing the vent motor, blower control, hot surface ignitor, and gas valve. The control provides diagnostic codes (flashing LEDs) to aid in testing and troubleshooting.
