- Ignition Control: Manages the ignition sequence for the main burner.
- Blower Motor Control: Activates and deactivates the indoor blower motor based on heating or cooling demands.
- Safety Monitoring: Monitors various safety limits and sensors to ensure safe operation and shut down the furnace if a fault is detected.
- Diagnostic LED: Provides diagnostic codes via a flashing LED to assist in troubleshooting (refer to the Troubleshooting section).
The specific operational sequence is determined by the furnace manufacturer's design and the thermostat's commands.
Maintenance
The ICM280 control board itself requires no routine maintenance. However, regular maintenance of the overall furnace system is crucial for its longevity and efficient operation. This includes:
- Kutsiva Sefa: Replace or clean the furnace air filter regularly (monthly or as recommended by the furnace manufacturer).
