Ice maker cycles water but ice does not release from the evaporator plate, forming a solid block.

Safety: Unplug the unit before accessing refrigerant valves or heaters. Sealed system work must be done by a qualified technician.

• Descale evaporator: Heavy scale can prevent ice from releasing. Use an approved descaling solution to clean the evaporator plate thoroughly.
• Check harvest thermostat: Test the thermostat or sensor that signals harvest temperature. Replace if it does not close/open at the specified temperature.
• Inspect wiring: Ensure wiring to the hot gas valve or harvest heater is intact and connectors are secure.
• Professional service: If the hot gas valve coil is open or the sealed system requires modification, contact a certified refrigeration technician.
