This high-performance Fan Relay is a critical electrical switching component designed for residential and light commercial HVAC systems. Featuring a 24V 50/60Hz coil, this relay acts as the primary controller for blower motors and condenser fans in air conditioning units and heat pumps. It works by receiving a low-voltage signal from your thermostat to safely engage the high-voltage circuit required to power the fan. If your HVAC fan fails to start, runs continuously, or makes a clicking sound without engaging, replacing the fan relay is a common solution to restore proper airflow and system efficiency. Built for durability and reliable electrical contact, this part ensures your cooling and heating systems cycle correctly to maintain a comfortable indoor environment.
