These temperature controls are double throw, single pole 
controls. The sensing tube is inserted into the ice maker mold 
and senses mold temperature. After ice is sensed in the mold, 
the 2-3 contacts open (stopping the compressor) and the 2-1 
contacts are closed (starting the ice maker motor). The 2-3 
contacts close (2-1 contacts open) before the end of the ice 
harvest cycle.The hold switch prevents power going back to 
the compressor. This prepares the control for the next cycle
.
