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, the ice maker may not operate properly.
Caution
Please read our safety information before attempting any testing or repairs.
Before testing 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. Follow the instructions specific to modular units.
- Component Units: Usually have exposed gears and don’t have holes for test probes.
Testing the Holding Switch (Component Units)
- Unplug the Refrigerator:
- Ensure the refrigerator is unplugged to avoid electrical shock.
- Access the Ice Maker:
- Remove the 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’s wiring harness from the freezer cabinet if not already done.
- Locate the Holding Switch:
- The holding switch is typically found near the control mechanism inside the ice maker.
- Remove the Outer Face Plate:
- If there is a knob, pull it off first.
- Use a small screwdriver to pry off the face plate.
- Test the Holding Switch:
- Set a multitester to the ohms setting (X1).
- Touch one probe to each terminal of the holding switch.
- The multitester should display a reading of zero or near zero ohms (indicating continuity) when the switch is closed (activated).
- If the multitester shows infinity (no continuity) when the switch is supposed to be closed, the holding switch is faulty and needs to be replaced.
Reassembly
- Reassemble the Ice Maker:
- After testing, reassemble the ice maker by reversing the disassembly steps.
- Reattach the wiring harness, secure the ice maker in place with screws, and ensure all connections are tight and secure.
- Plug In the Refrigerator:
- Once reassembled, plug the refrigerator back in and restore power.
By following these steps, you can effectively test the holding switch in your ice maker and determine if it needs to be replaced to restore proper function.
