Bunn ultra-2 compressor start relay 34255-0002 t-2155
This is a brand new Compressor Start Relay for the Bunn Ultra-2 machine.
A relay is a switch - this type of relay uses a low voltage signal to activate a magnetic coil that pulls a second set of higher-voltage electrical contacts together. Essentially this allows the main control board (computer) of the Ultra-2 machine to send a low voltage start signal to the compressor and the relay send higher voltage to the starting capacitor and compressor motor.
