Ice makers may have an embedded heater in the ice tray that operates when the temperature sensor senses ice is ready. The motorized scoop only needs enough power to gently move frozen ice crescents out to fall into the tray. This presumes the heater warmed up the tray for ice removal. You’ll need to study the wiring diagram to verify if a heater is used. If a heater is used, you can check for continuity or resistance as an open heater circuit isn’t repairable and the whole assembly will need to be replaced.
