Overview
The water inlet switch in an ice maker controls the flow of water into the ice mold. If the switch is faulty, it needs to be replaced to ensure the proper functioning of the ice maker.
Caution
Please read our safety information before attempting any testing or repairs.
Before replacing the water inlet switch, unplug the refrigerator to avoid an electrical shock hazard.
Identifying Your Ice Maker Type
- Modular Units: Have holes in the module’s face plate for test probes. If you see several holes, each marked with a letter, it is a modular unit. Refer to the section: control module for replacement instructions.
- Component Units: Usually have exposed gears and don’t have holes for testing.
Replacing the Water Inlet Switch (Component Units)
- Unplug the Refrigerator:
- Ensure the refrigerator is unplugged to avoid electrical shock.
- Access the Ice Maker:
- Remove the outer face plate of the ice maker. If there is a knob, pull it off first, then pry off the face plate with a small screwdriver.
- Remove the Ice Maker:
- It is easier to work on this type of unit by first removing the entire ice maker from the freezer compartment.
- The unit is usually mounted to the freezer case by two or more screws. Remove the bottom screws first.
- While supporting the ice maker, remove the remaining top screws.
- Unplug the ice maker from the freezer cabinet if you have not already done so.
- Locate the Inlet Switch:
- Along the edge nearest the shutoff arm, a pin protrudes through the cover plate (labeled “A” below). The arm pin has a spring under the cover plate.
- Reduce the tension on the spring by moving the shutoff arm into the “on” position, down, against the ice maker.
- Remove the Inlet Switch:
- Locate the inlet switch within the ice maker. It is typically a small switch connected by two wires.
- Label the wire placement on the switch before disconnecting the wires.
- The wires are connected to the switch with slip-on connectors. Firmly pull the connectors off of the switch terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors.
- Replace the Inlet Switch:
- Remove the faulty switch. The switch may be held in place with screws or clips. Use a screwdriver or appropriate tool to remove it.
- Install the new switch by aligning it with the mounting holes or clips and securing it in place.
- Reconnect the wires to the new switch terminals, ensuring they are securely connected.
- Reinstall the Ice Maker:
- Reattach the ice maker to the freezer case by first securing the top screws while supporting the unit.
- Then, secure the bottom screws.
- Plug the ice maker back into the freezer cabinet.
- Reassemble the Face Plate:
- Replace the cover plate and knob (if any).
- Restore Power:
- Plug the refrigerator back in and restore power.
- Move the shutoff arm into the “on” position, down, against the ice maker.
- Test the ice maker to ensure it operates correctly with the new water inlet switch.
By following these steps, you can effectively replace the water inlet switch in your ice maker and restore its proper function.
