- The ICM2811 is a form, fit, and functional Goodman OEM replacement board. The ICM2811 is an automated gas ignition control board which monitors the ignition sequence including the combustion air blower, pressure switch, hot surface igniter, gas valve, flame sense, and circulating blower while maintaining full safety circuit monitoring including the high limit switch, roll out switch and auxiliary limit switch circuits. Onboard diagnostics will illuminate a flash code to help technicians properly diagnose issues quickly.

Maintenance & Troubleshooting:
- This capacitor is typically replaced when diagnostics indicate a run capacitor is out of specification or when motor operation issues are traced to the dual run capacitor (diagnostic procedures are not provided in the supplied sources).
- If issues persist after replacement, confirm the installed capacitor matches the required MFD and voltage ratings and that all connections are correct per the equipment documentation.
Certifications & Compliance:
- Manufacturer listing states UL & cUL for these capacitors.
User Reviews & Q&A Summary:
- Review themes commonly describe it as a correct replacement capacitor that restores cooling operation when a failed capacitor is replaced.
- Many comments focus on getting the right part quickly and returning equipment to service, with frequent notes about straightforward replacement once the correct rating is confirmed.
