After successful installation and power restoration, the ICM280 control board will initiate the furnace's normal operating sequence. The board manages various furnace functions, including:
- Njikwa mgbanye: Manages the ignition sequence for the main burner.
- Blower Motor Control: Activates and deactivates the indoor blower motor based on heating or cooling demands.
- Nleba anya nchekwa: Monitors various safety limits and sensors to ensure safe operation and shut down the furnace if a fault is detected.
- LED achọpụtara: 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.
Nlekọta
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:
- Ndochi nzacha: Replace or clean the furnace air filter regularly (monthly or as recommended by the furnace manufacturer).
- Nyocha kwa afọ: Have a qualified HVAC technician perform an annual inspection and tune-up of your furnace.
- Ịdị ọcha: Keep the area around the furnace clean and free of obstructions.
Before performing any maintenance on the furnace, always disconnect electrical power at the main service panel.

The ICM280 features a diagnostic LED (labeled "STATUS" on the board) that provides flash codes to indicate operational status or fault conditions. Consult your furnace's specific manual for a complete list of diagnostic codes, as these can vary by furnace model. Common indications include:
- ONYE siri ike: Normal operation, no call for heat/cool.
- Flash ngwa ngwa: Normal operation, call for heat/cool.
- Ngwa ngwa ngwa: Indicates a fault condition. The number of flashes typically corresponds to a specific error code.
Usoro nchọpụta nsogbu izugbe:
- Enweghị ike: Check circuit breakers and furnace disconnect switch. Ensure the furnace door panel is properly closed, as many furnaces have a safety interlock switch.
- Furnace Not Starting:
- Verify thermostat settings are correct.
- Check for diagnostic codes on the STATUS LED.
- Inspect wiring connections on the control board for looseness or corrosion.
- Blower Not Operating:
- Ensure the thermostat is calling for fan operation.
- Check for diagnostic codes.
- Verify blower motor connections.
- Ọrụ na-adịte aka: This can often be caused by loose connections, faulty sensors, or intermittent power supply issues. Check all wiring and consult a qualified technician.
If you are unable to resolve an issue after following these steps, contact a qualified HVAC service technician.
