What might indicate a problem with an oil burner based on its operation?

An increased noise level during the operation of an oil burner can signal various potential issues that may need immediate attention. Noises such as popping, banging, or hissing can indicate a problem with combustion or fuel delivery. For instance, a popping noise may suggest improper fuel atomization or a delayed ignition, which can lead to inefficient operation or safety hazards. Similarly, abnormal sounds might be caused by issues with components such as the fan or pump, indicating wear or malfunction.

In contrast, steady heat generation and consistent oil flow typically suggest that the burner is functioning correctly. Low air pressure is a concern in certain contexts, but it doesn't necessarily correlate with a problem as directly as an increased noise level does. Monitoring these operational indicators is vital for ensuring that the oil burner runs efficiently and safely.
