ICM Controls ICM286 Furnace Control Board - Goodman PCBBF112S, B1809926S

Description

ICM Controls ICM286 Furnace Control Board - Replacement for Goodman
The ICM286 Furnace Control Board is a form, fit and functional replacement for Goodman's popular PCBBF112(S) or B1809926(S) control board. It features micro-processor based precision with a status LED for testing and easy troubleshooting.
Microprocessor-based precision
Controls inducer and blower fan motors, hot surface ignitor, and gas valve
Monitors timing, trial for ignition, flame sensing, pressure and limit switches, and lockout
Designed for 100% gas shutoff in case of ignition failure
Reverse polarity connection
Twinning compatible with another ICM286 board
Compatible with LP or natural gas
Diagnostic LED to aid in testing/troubleshooting

Main Operation
On the application of power, the control will continuously monitor the rollout switch, limit switch, pressure switch, gas valve output and flame sense. During a Call for Heat, the control makes sure the limit switch is closed and the pressure switch contact is open before turning on the Inducer blower, which will be energized for 15-seconds in a pre-purge mode. Following the pre-purge period, the pressure switch contact is closed and power is applied to the hot surface ignitor (there is a 7-second warm-up period). The gas valve is energized if a flame is sensed during this 7-second trial-for-ignition period, the blower motor will turn on following a 30-second delay. When the call for heat ends, the control will turn off the gas valve, the inducer blower will turn off after a 15-second post-purge period, and the heat blower will turn off after the jumper-selectable period of time (if jumper is missing, default Heat Blower Off delay is 120 seconds). During a Call for Cool, the control will energize the cool blower after a 5-second delay. When the call for cool ends, the control will turn the cool blower off after a 45-second delay.
Twinning
The ICM286 is Twinning compatible with another ICM286 control board only. By connecting the designated “TWIN” screw terminals and the 24 VAC common together, the controls are designed to turn on/off the blower simultaneously and at the same speed. (NOTE: An external AC relay, whose coil is connected between R & W of the primary furnace and whose normally open contacts connect R & W of the secondary furnace, must be provided to cause both furnaces to heat). A common ground between the two furnaces is also required.
