Double Throw Ice Maker Thermostat Numbers
4548, AR-19-12, 2636, 2690, 2691, 2717
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. This prepares the control for the next cycle.
