Which of the following could indicate a draft inducer problem in a furnace?

Low airflow through the ducts could indicate a draft inducer problem in a furnace because the draft inducer is responsible for pulling air into the combustion chamber and ensuring proper airflow for the system. If the draft inducer is malfunctioning or not operating efficiently, it can lead to insufficient airflow, resulting in less effective heating and potential issues with combustion, such as incomplete burning of fuel.

When the draft inducer isn’t functioning correctly, it can create air pressure imbalances, leading to reductions in airflow throughout the entire duct system. This could manifest as rooms that are not heating properly or a noticeable decrease in the overall comfort level within the space. Proper functioning of the draft inducer is crucial for effective furnace performance and safety, making low airflow an important indicator of potential issues with this component.

Other choices may relate to various problems in the system, but they do not specifically point to issues with the draft inducer as clearly as low airflow does. For instance, unexplained power surges typically relate to electrical issues rather than air movement. Inconsistent thermostat readings can stem from multiple factors, including location, calibration issues, or sensor malfunctions, which do not directly correlate with the draft inducer's operation. Unlit burners indicate a lack of combustion, which could
