Evaporator sensor

Evaporator Sensor is an ice maker replacement part identified by part number 1851700900. It’s intended for service and repair when the original component is worn, damaged, or missing. Use the part number on your machine or old component to confirm you’re ordering the correct item. A temperature sensor like this is used by the control logic to decide when to continue freezing, initiate harvest, or protect the unit from abnormal temperatures. A faulty sensor can lead to intermittent operation—freezing too long, harvesting too early, or stopping with an error condition depending on how the unit monitors temperatures. If the ice maker responds unpredictably to temperature changes, replacing the sensor is often considered after ruling out wiring and control issues. Replacing the part can bring the system back to predictable operation and help prevent repeat call-backs. During replacement, disconnect power, handle the sensor lead carefully, and ensure the connector seats fully to prevent intermittent signals. A careful inspection of adjacent parts can help catch secondary issues that may have contributed to the failure. If the symptom is intermittent, pay close attention to connectors, mounting points, and any signs of vibration-related wear. Before closing panels, double-check that fasteners are snug and that nearby lines or wires won’t rub during operation.
