Ice Production/Quality Check QUALITY CHECK Ice quality varies with ambient and water temperatures, and is measured by the amount of water in the ice. Generally speaking, higher incoming water temperature results in lower ice quality. Lower water temperature results in higher ice quality. ICE PRODUCTION CHECK NOTE: Ice production checks that are within 10% of the charted capacity are considered normal due to...
Thermostat Settings Bin Thermostat: The bin thermostat sensing bulb is located in the ice chute on modular models and in the bin thermostat holder on the right side of the bin on self storage models. The bin thermostat turns the ice machine on and off as the level of ice in the bin changes.
