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.

Normal operation – Stage 5
As the compressor comes up to normal running speed, its start winding generates a voltage potential across the
relay’s coil. 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.
