In the case of a high-efficiency furnace where the main burner shuts off after initial ignition, the issue is likely related to one of the following components:

1. **Flame Sensor**: This component detects whether the burner is lit. If it is dirty or malfunctioning, it might not detect the flame, causing the system to shut off the burner as a safety precaution.

2. **Ignition System**: If the ignition system is faulty, it might not sustain the flame after initial ignition.

3. **Gas Valve**: A malfunctioning gas valve might not supply a consistent flow of gas to keep the burner lit.

4. **Pressure Switch**: This ensures that the exhaust venting is working properly. If it fails, it might shut off the burner.

5. **Thermostat**: Ensure that the thermostat is functioning correctly and is set to the desired temperature.

Testing these components can help identify the root cause of the problem. It is advisable to consult a professional technician to perform these tests safely and accurately.
