The situation where a furnace blower runs but does not produce enough heat can stem from multiple issues, which encompasses all the listed possibilities.

A malfunctioning thermostat can lead to improper temperature readings or controls, resulting in the furnace not operating at the desired setting. If the thermostat fails to signal the furnace properly, the system may operate continuously without reaching the necessary heat output.

A dirty air filter can significantly impede airflow. If the filter is clogged, it restricts the air entering the furnace, leading to insufficient heat being circulated throughout the space. This can cause the blower to run continuously, but with inadequate heat generation due to poor airflow.

An insufficient gas supply can prevent the burners from lighting or producing adequate heat. If the gas supply is low or interrupted, even if the blower is functioning and the system is on, the furnace will not heat effectively.

Given that each of these issues can independently cause insufficient heating while the blower is operational, it's correct to conclude that any of these conditions might be at play. Therefore, recognizing that each potential problem contributes to the overall issue leads to the understanding that a resident could report all of the factors as the root cause of inadequate heat production from the furnace.
