FAQs
What is a furnace replacement relay and how does it work?
A furnace replacement relay is an electrical component that plays a crucial role in the operation of a furnace. It acts as a switch that controls the flow of electrical current to the furnace’s heating elements, such as the burners or heat exchanger. The relay receives a low-voltage signal from the furnace’s control board and uses it to activate or deactivate the heating elements. This process allows the furnace to turn on and off as needed to maintain a consistent temperature.
The relay works by using an electromagnetic coil to open or close a set of contacts. When the coil is energized, it pulls the contacts together, allowing the electrical current to flow to the heating elements. When the coil is de-energized, the contacts open, and the current is interrupted. This process happens quickly and repeatedly as the furnace cycles on and off. A faulty relay can cause the furnace to malfunction or fail to operate altogether, which is why replacing it with a new one is essential to restore the furnace’s functionality.
