What to do if 'EE' is observed in left display area during Diagnostic Mode of Sub-Zero Ice Maker?

If you see “EE” in the left display area during Diagnostic Mode on your Sub-Zero Ice Maker, it means the thermistor is either open or shorted, or there's a break in the thermistor's wiring. You should replace the faulty thermistor or repair the wiring connections.
