Normal operation – Stage 4 One second (1 s) after the fan comes on, the COMPRESSOR output comes on. The compressor circuit uses both run and start capacitors along with a potential start relay. The start capacitor in energized through the normally closed contacts of the start relay.

This energizes the coil to open the contact and drop out the start capacitor. The ice machine is now in a normal ice making mode. The ice machine will produce ice until the bin level control in the ice dispenser is satisfied. T.O.L.
