Normal operation – Stage 3 – Refrigeration start
Seconds later the C LEDs come on and the coils of both of the relays are energized, closing their normally
open contacts. This completes the circuit to the coil of the liquid line solenoid valve. The valve opens increasing
the pressure in the suction line. The low-pressure control then starts the condensing unit. As the gearmotors
reach normal speed the current relays re-open, dropping out their start windings. The icemaker is now in normal
icemaking mode.
