ICM Controls ICM2920 Ignition Control

The 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.

Designed for professional-grade HVAC furnace control board replacement, the ICM2920 features a selectable heat blower off-delay and integrated anti-short cycle protection for the cooling compressor. For contractors troubleshooting in the field, the onboard LED provides diagnostic flash codes that simplify fault identification. This board is versatile enough for 2-stage cooling systems by simply removing the breakaway tab, and it operates across a wide line voltage range of 24 to 230 VAC (RMS).

• Direct Replacement: Precisely swaps with Goodman PCBAG123 and PCBAG123S controls.
• Enhanced Diagnostics: Onboard LED status lights provide clear furnace troubleshooting codes for faster service calls.
• System Protection: Integrated anti-short cycle timer prevents compressor damage from rapid cycling.
• Flexible Applications: Supports both single and 2-stage cooling configurations with selectable blower delays.
• Rugged Reliability: Designed to withstand harsh mechanical and electrical environments common in residential HVAC.

Common Questions:

Will this work with my existing spark ignitor?
Yes, the ICM2920 is designed to control the direct spark ignition sequence using your existing ignition components, provided they are in good working order.

Does this board support cooling systems?
This control manages the circulating blower and the compressor contactor, providing short-cycle protection and selectable off-delays to optimize cooling performance.

How do I clear a lockout condition?
A lockout caused by ignition failure or flame loss can be reset by removing 24 VAC power for at least 3 seconds or by cycling the thermostat's call for heat.
