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.
