Step-by-Step Replacement Guide
⚠️ SAFETY FIRST
Always unplug your refrigerator from the power outlet and shut off the water supply before beginning any repair work. This prevents potential electrical shock and water damage.
Step 1: Safety Preparation
- Unplug your refrigerator from the electrical outlet.
- Locate and turn off the water supply valve that feeds the refrigerator.
- Place towels or a bucket underneath the water line connection to catch any water spillage.
Step 2: Access the Ice Maker Assembly
- Open the left French door of your refrigerator (the side with the ice dispenser).
- Locate and unlatch the ice compartment door inside the refrigerator.
- Remove the ice bin by lifting it upward and then pulling it outward and away from the compartment.
- Set the ice bin aside in a safe place where it won’t get damaged.
Step 3: Disassemble the Panel
- Locate and remove the three Phillips screws at the base of the ice compartment.
- Find and loosen (but don’t completely remove) the top screw of the panel.
- Gently pull the panel downward to expose the wiring harness behind it.
- Disconnect the wiring harness by pressing the locking tab with a flathead screwdriver and carefully unplugging it.
- Pro Tip: Take a photo of the wire connections before disconnecting to ensure proper reassembly later.
Step 4: Remove the Old Assembly
- Detach the auger coupling by unscrewing the Phillips screw that secures it and carefully slide the coupling off.
- Remove the two Phillips screws that secure the motor assembly to the refrigerator.
- Carefully flip the assembly and disconnect the ground wire.
- Free the wiring harness by gently peeling back any adhesive tape and unplugging the motor connector.
- Set aside the old assembly to make room for the new one.
⚠️ CAUTION
Handle the auger coupling with care. Forcing or misaligning it can damage the gears and potentially require additional repairs.
Step 5: Install the New Assembly
- Connect the wiring harness to the new motor assembly.
- Secure the ground wire with the Phillips screw.
- Position the new motor assembly by aligning the screw holes with the mounting points.
- Tighten the screws to secure the assembly in place, being careful not to overtighten.
- Reattach the auger coupling and secure it with the Phillips screw.
- Route the wiring harness through the designated channel and reapply adhesive tape to secure it properly.
Step 6: Reassemble and Test
- Reinstall the panel and secure it with the previously removed screws.
- Replace the ice bin in its original position.
- Latch the ice compartment door securely.
- Plug the refrigerator back in and turn the water supply back on.
- Wait 2-4 hours for the first batch of ice to be produced before testing the dispenser.
Troubleshooting After Installation
Still No Ice Production?
- Check that the water supply line isn’t kinked or frozen.
- Verify the water filter is properly installed and not clogged.
- Ensure the freezer temperature is set between 0°F and 5°F (-18°C to -15°C).
Water Leaking?
- Ensure the water inlet tube is seated properly and securely.
- Check all connections for proper alignment and tightness.
- Look for any cracks in the water line or components.
Motor Not Running?
- Verify all electrical connections are secure.
- Test the continuity of the motor with a multimeter if available.
- Check for any error codes on the refrigerator display.
