Microswitch

Microswitch is an ice maker replacement part identified by part number 1871018500. 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 switch like this is used to control operation at the panel or service area, helping the technician or operator manage the machine. If the switch contacts are inconsistent, the machine may cut out unexpectedly or fail to respond when toggled. If moving the switch changes the symptom, replacement is often the simplest fix once wiring is confirmed. Replacing the part can bring the system back to predictable operation and help prevent repeat call-backs. Ensure the switch is mounted securely so vibration doesn’t lead to intermittent contact. A careful inspection of adjacent parts can help catch secondary issues that may have contributed to the failure. Before closing panels, double-check that fasteners are snug and that nearby lines or wires won’t rub during operation.

When possible, run the ice maker long enough to observe at least one complete cycle after the repair. If the symptom is intermittent, pay close attention to connectors, mounting points, and any signs of vibration-related wear.
