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.
