Diagnosis Guide
Tools Needed:
- Multimeter
- Nut driver set
- Screwdrivers (flat and Phillips)
- Pliers
- Putty knife
- Ice maker test harness
Step-by-Step Diagnosis
- Initial Inspection: Check for visible damage to ice maker components, wiring harness, and water supply line.
- Water Supply Check: Verify water is reaching the ice maker. Check water inlet valve and supply line for restrictions.
- Electrical Testing: Test for proper voltage at ice maker connector. Check for 120V AC at the inlet valve.
- Thermostat Test: Test ice maker thermostat for continuity at room temperature (should be closed).
- Motor Test: Test ice maker motor for proper operation using test harness or direct voltage application.
- Harness Inspection: Check wiring harness for damage, corrosion, or loose connections.
- Control Board Test: If all components test good, check refrigerator control board for proper ice maker signals.

Replacement Procedure
- Disconnect Power: Unplug refrigerator or disconnect at circuit breaker.
- Remove Ice Bin: Slide ice storage bin out of freezer compartment.
- Remove Cover: Remove ice maker cover (if applicable) by releasing tabs or removing screws.
- Disconnect Wiring: Disconnect wiring harness from ice maker assembly.
- Disconnect Water Line: Disconnect water supply line from inlet valve (have towel ready for residual water).
- Remove Mounting Screws: Remove screws securing ice maker to freezer wall.
- Install New Unit: Position new ice maker, secure with mounting screws, reconnect water line and wiring.
- Test Operation: Restore power, initiate test cycle, check for leaks and proper ice production.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No ice production | Water supply issue, faulty inlet valve, ice maker not receiving power | Check water supply, test inlet valve, verify 120V at ice maker connector |
| Small or misshapen ice | Low water pressure, restricted water line, faulty water inlet valve | Check water pressure (min 20 psi), inspect water line, replace inlet valve if defective |
| Ice maker runs continuously | Faulty thermostat, stuck harvest cycle, control board issue | Test thermostat continuity, check harvest mechanism, test control board signals |
| Ice cubes stuck in mold | Heater element failure, thermostat stuck open, low voltage | Test heater element for continuity, test thermostat, check voltage supply |
| Water leaking from ice maker | Cracked water tube, loose connection, overfilling | Inspect water distribution tube, check all connections, verify fill time |
| Ice tastes bad | Old ice, water filter needs replacement, contaminated water supply | Discard old ice, replace water filter, check water source quality |
Error Codes & Diagnostics
- No Power Light: Check power supply, wiring harness, control board
- Continuous Run: Test thermostat, check for stuck harvest mechanism
- No Water Fill: Verify water supply, test inlet valve, check water line
- Ice Not Ejecting: Test heater element, check for ice blockages
- Motor Humming: Check for jammed gears, test motor windings
- Slow Ice Production: Check freezer temperature (should be 0°F), verify water pressure
