Understanding the Problem
Brief explanation: The KSRS25RSWH00 uses a modular ice maker and a water inlet valve to make ice. When ice stops forming, it’s usually one of three systems: water supply (valve/filter/lines), freezer temperature or ice maker electronics/motor. This guide walks you through step-by-step diagnostics and practical fixes so you can isolate the faulty part and repair it. Step-by-step diagnostic & repair instructions: 1) Confirm the symptom and basic settings - Symptom check: no ice production, slow/partial fill, small/odd-shaped cubes, or ice jam/overflow. - Check freezer temperature: ideal is about 0°F to 5°F (-18°C to -15°C). If warmer than ~10°F, the ice maker won't harvest properly. Adjust temp, wait 24 hours and retest. 2) Inspect for obvious mechanical jams - Open the ice bin and remove it. Look for ice blockages, frozen lumps or a stuck ejector arm. Clear any ice chunks with warm (not boiling) water and a plastic tool. Do not use metal tools. - Manually move the ejector/auger to ensure it turns freely. If it’s seized, that could be a bad motor or jam. 3) Verify water supply and filter - Check the house shutoff to the refrigerator and the shutoff valve behind the fridge are fully open. - Replace the water filter if it’s old or clogged (a clogged filter reduces or stops fill). After replacing the filter, purge the line per the filter instructions. - Confirm water dispenser operation: if the dispenser has poor flow, the inlet valve or supply is suspect. 4) Test the water inlet valve (practical test) - Locate the water valve at the rear lower left of the refrigerator. Turn off water supply and unplug the fridge before disconnecting hoses. - With power on and calling for ice fill (see next step to start ice maker), listen for a click at the valve. If you have a multimeter, check for 120VAC (or appliance-rated voltage) to the valve solenoid during a fill cycle. If voltage is present but no water flows, replace the valve. 5) Run an ice maker diagnostic/harvest cycle - Many KitchenAid ice makers have a test/diagnostic button on the module or you can use the dispenser controls to start diagnostics (refer to the owner manual for exact sequence). Another manual method: raise the feeler arm and then push the test button / rotate motor to cycle. - Observe: does the motor run (auger/ejector turns) and does the valve open (you should hear a click and water flow into the fill cup)? - If motor runs but no water — suspect inlet valve, filter, or frozen line. If valve clicks and water flows but mold doesn’t freeze — check freezer temperature, mold heater, or thermostat/thermistor. 6) Check the ice maker module / motor / thermostat - If the ice maker won’t cycle (no motor noise, no harvest), check the ice maker harness for power and continuity. Unplug the fridge or switch off power before unplugging the ice maker connector. - With a multimeter, test for continuity in the ice maker motor/thermostat according to the ice maker schematic. If the module has no continuity where expected or the motor is dead, replace the ice maker assembly. 7) Replace suspected faulty parts - Common replacements: water inlet valve (if it fails to open or is leaking), ice maker assembly/module (motor/gears/electronics), water filter (if clogged), or temperature sensors/thermostat (if freezer not cold enough). - Replacement steps (ice maker assembly example): a) Unplug refrigerator and shut off water supply. b) Remove ice bin and unscrew the ice maker from the freezer interior (usually 2–4 screws) and disconnect the wiring harness. c) Transfer mounting bracket if needed and install new assembly. Reconnect harness, secure with screws, replace ice bin. d) Turn on water, plug in fridge, and run an ice maker test cycle. Check for proper fill and any leaks. 8) Run verification and break-in - After repair, allow several cycles: initial fill, freeze (6–24 hours depending on temperature) and harvest. Expect the first few cycles to be slow; discard the first 1–2 batches of ice after replacing water components. Safety note: Always unplug the refrigerator and shut off the water supply before disconnecting wiring or water lines. Use insulated tools, wear gloves for cold and pinch protection, and do not use metal tools to pry or chip ice inside the mold.
Common Symptoms
No ice, slow or partial fills, small/weak cubes, ice bin full of a frozen block, or ice maker not cycling.
Common Causes
- Clogged/old water filter or restricted water supply
- Faulty water inlet valve or frozen water line
- Failed ice maker module/motor/gears or thermostat (thermistor)
- Freezer temperature set too warm or airflow obstruction
- Ice jam or mechanical obstruction in the ice mold or ejector

Helpful Repair Tip
Run a harvest/test cycle and listen: if you hear a click (valve) but no water, the inlet valve or water line is the likely fault. If you hear motor noise but the ejector doesn't move, the ice maker module or gears are bad.
Frequently Asked Questions
How do I reset the ice maker on my KSRS25RSWH00?
Most KitchenAid ice makers reset by running a test/harvest cycle: locate the test button on the ice maker module and press/hold per the manual (usually ~10 seconds), or use the refrigerator diagnostics via control panel if available. If the ice maker has a feeler arm, lower it to the run position. If reset doesn't correct the issue, run diagnostics to see if motor/valve are operating.
Can I replace the ice maker or inlet valve myself, or should I call a technician?
You can replace both yourself if you’re comfortable with basic tools: unplug the fridge, shut off water, remove panels, disconnect harness and water line, swap parts and reseal connections. However, if you’re not comfortable working with electrical connectors, water lines, or verifying voltage, call a pro to avoid leaks or electrical damage.
