Always verify your specific circuit’s amperage draw against the technical ratings

While rated for high-pressure industrial use (up to 200 PSI @ 400°F)

the switch closes on pressure rise to start the condenser fan and opens when the pressure drops below the setpoint minus the differential

Using a multimeter set to DC millivolts

Key Benefits for HVACR Contractors Precise Signal Selection: Automatically transmits the lower of two pneumatic signals for accurate sequence control and safety interlocking

ICM Controls ICM2920 Ignition Control 30067439-890 Always verify your specific circuit’sThe ICM Controls ICM2920 Ignition Control is a form, fit, and functional direct replacement for PCBAG123S and PCBAG123, engineered specifically for Goodman spark ignition furnace systems. This microprocessor based automated gas ignition control board monitors the critical heating sequence, including the inducer, pressure switch, spark ignition, and gas valve, while maintaining high level safety monitoring for limit and rollout switches.
