Understanding the Problem
This guide covers common ice-maker problems on GFSS6KKYESS-style refrigerators (no ice, slow or small ice, leaks, or ice dispenser failures) and how to diagnose and repair them. Follow these ordered steps to identify the faulty component and fix the issue. 1) Confirm the symptom and environment - Note exactly what’s happening: no ice produced, small/soft ice, ice clumped together, water leaking, or dispenser not delivering ice. Check freezer temperature (should be about 0°F / -18°C). Ensure the freezer door is sealing. 2) Quick checks (do these first) - Check water supply: Ensure the shutoff valve to the fridge is fully open and the water line is not kinked. If the line was recently reconnected, purge air by cycling the dispenser to run water a minute. - Replace the water filter if it’s old or clogged (filter can restrict fill volume and slow ice production). - Verify freezer temperature and allow 24 hours if the fridge was recently re-stocked or power-cycled. 3) Basic functional tests - Manually advance the ice-maker (if accessible) or run the fridge diagnostic/ice-maker test cycle (consult your service manual for exact steps for GFSS6KKYESS). Listen for the ice-maker motor and the fill valve energizing. - Observe a fill cycle: the fill valve should open for a short time and water should flow into the ice mold. If no water flows, suspect the inlet valve, clogged fill tube, or water supply. 4) Inspect common failure points (in priority order) - Water inlet valve: Often fails electrically or becomes calcified. If the valve does not open (no click or no continuity on the solenoid), the ice maker will not fill. - Ice maker module (ejector motor / control): If the motor doesn’t run or the unit won’t harvest ice, the module is likely defective. - Frozen/blocked fill tube: Ice can form in the fill tube if the heater or defrost around it fails; a thawed tube will restore fill. - Water filter: A clogged filter restricts flow and reduces ice production. - Ice sensor / level switch / bin detection: If the sensor thinks bin is full, it won’t run. 5) Diagnostic steps with tools - Tools: multimeter, nut driver or Phillips, flashlight, small mirror, hairdryer (for thawing), towels, bucket. - With power off, remove the ice bin and inspect the ice maker for broken gears, jammed ejector blades, or physical ice jams. - With the fridge powered and in test mode (or while running a harvest/fill cycle), use the multimeter to check for 120VAC (or the model’s expected voltage) at the ice maker fill valve when the unit calls for water. If voltage is present and no water flows, replace the valve. - Check continuity of the ice-maker motor/thermostat/thermistor according to service manual specs. No continuity or out-of-spec readings indicate replacement. 6) Repair / replacement procedures (general steps) - Replace the water inlet valve: a) Shut off the water supply and unplug the refrigerator. b) Pull the fridge away from the wall and remove the rear lower access panel. c) Disconnect the water tubing at the valve (have towels/bucket ready). Disconnect the electrical connectors. Remove mounting screws and swap in the new valve. Reconnect wiring and water line, turn water on, check for leaks. - Replace ice maker assembly: a) Unplug the refrigerator and remove the ice bin. b) Remove securing screws holding the ice maker module to the freezer wall. c) Disconnect the electrical connector and (if present) the water fill line quick-connect. d) Remove the old assembly and install the new unit in reverse order. Reconnect water line, plug in fridge, run test fill/harvest cycle. - Thaw frozen fill tube: a) Turn off the ice maker or unplug the refrigerator. b) Carefully apply warm air (hairdryer on low) to the fill tube openings in the freezer door area until water flows freely. c) Restore power and run a fill cycle. 7) Test and verify - After replacing parts, run a manual fill/harvest cycle or place the fridge in diagnostic mode. Observe a fill and a harvest. Allow 24 hours for a full ice batch. Safety note: Always unplug the refrigerator (or switch off its circuit breaker) before working on electrical components. Shut off the water supply before disconnecting water lines to avoid flooding. Use gloves and eye protection when working with tools and frozen components.
Common Symptoms
No ice production, reduced/slow ice production, small or soft ice cubes, ice maker not cycling or ejecting ice, water leaking under fridge or into freezer, dispenser not dispensing ice.
Common Causes
- No/low water supply or closed/kinked water line
- Failed water inlet valve or clogged water filter
- Defective ice maker motor/module, thermostat, or ice-level sensor

Helpful Repair Tip
Remove the ice bin and manually advance the ice-maker clutch or run the refrigerator’s diagnostic “harvest” cycle; if you hear the motor run but no water flows, the inlet valve is the most likely fault.
Frequently Asked Questions
My ice maker suddenly stopped making ice overnight — what should I check first?
First, confirm the water supply is on and the line is not kinked. Check and, if necessary, replace the water filter. Verify freezer temperature is around 0°F (-18°C). Remove the ice bin and look for jams. If the ice maker makes noise but no water fills, suspect the inlet valve; if it is silent and does not cycle, suspect the ice maker module or its power supply.
How long after a repair or replacement will I see ice again?
After replacing an ice maker or inlet valve, expect the first successful fill immediately when the unit calls for water; however, it takes about 2–24 hours for the molds to freeze into full-size cubes and up to 24 hours for a full new batch depending on load and temperature. Run a manual test fill/harvest if your model supports it to verify operation right away.
