This professional-grade 24V SPDT (Single Pole Double Throw) relay is a critical electrical component designed for high-performance switching in HVAC systems and various household appliances. Featuring a 24-volt coil and a robust 15-amp contact rating, this relay acts as an electromechanical bridge, allowing low-voltage control signals from a thermostat or control board to safely manage high-voltage components like blower motors, fans, and compressors. It is a versatile replacement part commonly used in furnaces, air handlers, and heat pump units to ensure reliable power distribution and system timing. Replacing a faulty or sticking relay is essential for restoring efficient heating and cooling cycles and preventing intermittent system failures or electrical chattering.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
