Refer to normal operation before troubleshooting - The T5
thermistor reading must indicate 36 F or less in the freeze
cycle and throughout the harvest cycle to shutoff on full
bin at the end of the harvest cycle.
View the T5 thermistor temperature on the touch screen
(menu/service/diagnostics/temperatures).

400 F:
A shorted bin level probe wire/thermistor will indicate a
temperature higher than 400 F. This issues will result in
the ice machine only stopping on full bin when the bin
switch (curtain) is open at the end of a harvest cycle. The
ice machine will restart when the curtain closes.
