Overview
The holding switch in an ice maker ensures that the cycle proceeds correctly by maintaining the electrical connection needed for various functions. If the holding switch is faulty, it needs to be replaced to restore proper ice maker operation.
Caution
Please read our safety information before attempting any testing or repairs.
Before replacing the holding 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 control module section for replacement instructions.
- Component Units: Usually have exposed gears and don’t have holes for test probes.
Replacing the Holding Switch (Component Units)
- Unplug the Refrigerator:
- Ensure the refrigerator is unplugged to avoid electrical shock.
- Remove the Ice Maker:
- Remove 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 not already done.
- Access the Holding 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 cover plate by unscrewing or unclipping it as necessary to expose the internal components, including the holding switch.
- Remove the Holding Switch:
- The switch will be connected by two wires (four wires if it also controls additional features). 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.
- Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.
- Install the New Holding Switch:
- Connect the wires to the new switch using the slip-on connectors. Ensure they are securely attached and match the labeled positions.
- Position the new holding switch in place and secure it with any screws or clips that held the old switch.
- Reassemble the Ice Maker:
- Replace the cover plate and ensure all components are properly secured.
- Move the shutoff arm back to its normal position.
- Reinstall the Ice Maker:
- Reattach the ice maker to the freezer case with the mounting screws. Start with the top screws to support the unit, then secure the bottom screws.
- Plug the ice maker’s wiring harness back into the freezer cabinet.
- Restore Power:
- Plug the refrigerator back in and restore power.
- Test the ice maker to ensure it operates correctly with the new holding switch.
By following these steps, you can effectively replace the holding switch in your ice maker and restore its proper function.
