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.
