UC2024 and UC2724 Service Manual

Timed Cycles

Normally the control system operates with the
evaporator thermistor controlling cube size and the
flap / curtain switch controlling harvest time.
If the evaporator thermistor would fail to register a
temperature in the expected range (its resistance
reading open or shorted), the controller will still go
thru a freeze cycle, except it will be timed. This is
indicated by flashing of all cube size and harvest time
lights.
Cube size will likely not be as before, and could be
much larger or somewhat smaller than desired.
There is a maximum harvest time, and
if the flap / curtain switch has not been
triggered by that time, the controller
will return to a freeze cycle and the
green Bin Full light will blink. If, after
three consecutive harvest cycles the
flap / curtain switch has not been
triggered, the controller will shut down
ice making for one hour. If after twelve
cycles the flap / curtain switch has not
been triggered, the controller stops ice
making. The Bin Full light will remain
blinking.
Timed freeze: 1000 seconds.
Maximum harvest: 2 minutes.
