What device can be installed to prevent an electric furnace's indoor blower from turning off immediately?

A temperature-sensitive off-delay switch is designed to ensure that an electric furnace's indoor blower continues to operate for a certain period after the heating element has turned off. This feature helps to maximize heat distribution throughout the space and prevents the abrupt cessation of airflow, which can lead to uncomfortable temperature fluctuations.

By maintaining airflow after the heating cycle ends, the off-delay switch allows residual heat in the furnace to be transferred into the living space, ensuring that the area remains warm for a longer duration. This gradual cooling off helps to conserve energy and provides a more comfortable environment. The technology behind the temperature-sensitive mechanism ensures that the blower functions according to the temperature level within the furnace, enhancing efficiency and user comfort.
