Nordyne 104381000R Relay

The Nordyne 104381000R Relay is an electrical switching component used to control and coordinate circuit operation. It works by receiving a low-power control signal and transferring it to a higher-load circuit, enabling controlled activation of connected system parts. The relay is designed as part of control assemblies where signal switching is required between thermostats, motors, and other electrical components. In HVAC systems, it is commonly installed in furnaces and air handling units, supporting structured electrical communication between control boards and operational circuits.
