Furnace Relays and Contactors

A Furnace Relay is responsible for relaying electrical power to the furnace’s heating elements and the blower motor. It is a very crucial part in the operation of the furnace- the Thermostat switches off the relay to send power to heating elements to heat the warm air, and the blower motor sends the warm air throughout your home. Consequently, when the thermostat reaches the target temperature, it switches the relay on to cut the power.

A faulty relay will cause heating elements and fans to fail to turn or refuse to shut off. A faulty thermostat, tripped circuit breakers, or unlit pilot lights are some problems that can cause the relay to break.

If the fan is only running, there’s rattling noises and poor heat regulation, your furnace relay may be malfunctioning. If it is left unchecked, it can result in a blown fuse and even bigger damage.

If you conclude that your relay switch is broken, you have come to the right place. We have a variety of affordable and dependable relays for your unit. Can’t find what you’re looking for? Contact us for any questions or assistance you may need.
