Thermistor
The thermistor is the primary feedback component that monitors the evaporator's suction line temperature. In Hoshizaki logic, the control board will not start the critical 90-second harvest timer until this sensor reaches a specific temperature threshold (usually 48°F); if the sensor is open or has drifted in resistance, the unit will fail to harvest and eventually trigger a safety shutdown.

Water Inlet Valve
Hoshizaki machines utilize a 'water-assist' harvest where fresh water flows over the back of the evaporator to provide thermal energy. If the solenoid valve is restricted by sediment or has a failing coil, the lack of warm water prevents the ice from breaking its surface tension bond with the stainless steel plates, causing the ice to hang.

Scale Remover / Descaler
The physical interface between the ice and the evaporator must be perfectly smooth. Mineral scale (calcium/magnesium) creates a micro-porous surface that acts like an adhesive, physically 'hooking' the ice cubes to the evaporator assembly and preventing them from sliding off during the defrost cycle.
