Understanding the Problem
Brief explanation: Many problems that look like an icemaker failure are caused by the water supply or the fill system rather than the icemaker motor/module itself. On a GD5RHAXNT01 (check your unit's tech sheet for exact model details) the icemaker assembly, water inlet valve, fill tube and temperature control are the major suspects. Below are practical diagnostic and repair steps you can follow to pinpoint and fix the issue. Diagnostic & repair steps: 1) Confirm symptom and baseline checks - Observe what’s happening: no ice produced, slow production, tiny/hollow cubes, continuous water leak, or icemaker clicking but not ejecting. - Check freezer temperature: ideal is ~0°F to 5°F (-18°C to -15°C). Temps warmer than 10°F will reduce or stop ice production. - Replace or check the water filter (if equipped) and make sure the water supply valve to the fridge is fully open. 2) Check for obvious problems - Inspect the fill tube (metal or plastic tube that delivers water to the ice mold) for ice blockages. If frozen, thaw with a hair dryer on low or a warm cloth (don’t use boiling water). - Look for water in the icemaker tray (indicates valve or overfill problem). 3) Run the icemaker through a manual cycle - Remove the icemaker cover (if equipped) and locate the two test/jumper terminals or the harvest mode jumper. With the refrigerator powered, momentarily jump the test terminals to start a cycle (consult your service manual for exact terminals). The icemaker should go through a harvest and fill sequence. - Observe behavior: if the motor runs and ejects but no water fills, suspect the water inlet valve or kinked/clogged water line. If it doesn’t move or motor hums but won’t turn, suspect a bad module/motor or seized gears. 4) Test the water inlet valve - With the icemaker calling for water (during the test cycle), check for 120VAC (or manufacturer specified voltage) at the inlet valve solenoids with a multimeter. No voltage suggests a control/module problem; voltage present but no water means a bad valve or blocked line. - Check supply pressure and hoses under the sink/behind fridge for kinks. 5) Electrical/continuity checks on the icemaker - Unplug the refrigerator. Remove the icemaker and test motor and heater/mold thermostat continuity with a multimeter per the wiring diagram. No continuity on the motor or module usually means replacing the icemaker assembly. - Inspect wiring harness and connector pins for corrosion or loose connections. 6) Replace suspect part(s) - If the inlet valve won’t open when energized, replace the water inlet valve. - If the icemaker motor/module doesn’t run or the unit will not harvest/eject despite power, replace the icemaker assembly. 7) Reassembly and test - After replacement, restore power and water, run a manual test cycle, and verify proper fill, harvest, and eject sequences. Expect the first batch to take longer (new parts need normal cycle time). 8) Final checks - Verify freezer temperature, check for leaks, ensure cubes form properly over the next 24–48 hours. Safety note: Always unplug the refrigerator and shut off the water supply before disconnecting electrical connectors or water lines. Use insulated tools, and if you’re unsure about live-voltage checks, hire a qualified technician.
Common Symptoms
No ice production, slow or reduced ice output, small/hollow cubes, clicking or humming without ejecting, water in ice tray, or constant dripping into tray.
Common Causes
- Clogged/old water filter or shut water supply
- Faulty/blocked water inlet valve
- Frozen fill tube (ice bridge)
- Failed icemaker module, motor or thermostat
- Freezer temperature too warm
- Damaged wiring or harness/connectors

Helpful Repair Tip
To confirm if the icemaker itself is bad, place the icemaker into a manual test/harvest cycle using the test/jumper terminals: if the motor runs and it ejects but no water comes in, the inlet valve or water supply is bad; if it doesn’t cycle at all the icemaker module/motor is likely failed.
Frequently Asked Questions
How long should it take for a replaced icemaker to make ice?
After installing a new icemaker or water valve, it can take 8–24 hours for the first tray to freeze solid and up to 48 hours to reach normal production. Ensure freezer is at 0°F to 5°F and water supply is stable.
Can I test the water inlet valve without removing it?
Yes. Put the icemaker into a fill cycle and check for voltage at the valve solenoid. If voltage is present and no water flows, the valve is defective or the line is blocked. If no voltage, the problem is upstream (icemaker module, wiring, or control board). Always disconnect power before removing or replacing the valve.
