A silent ice maker when you need cubes most is more than an inconvenience—it disrupts your routine. If your Whirlpool Wrs588Fihz00 ice maker has stopped producing ice, this guide walks you through every practical fix, from the simplest resets to decisions about professional service. No guesswork, no wasted time.
Why Your Ice Maker Stopped Working
Before diving into repairs, understand the three main failure categories. Most problems fall into temperature issues, water supply problems, or component failures. Knowing which you're dealing with halves your troubleshooting time.
Temperature Problems That Stop Ice Production
The Wrs588Fihz00 requires a freezer temperature between 0°F and 5°F (-18°C to -15°C) to make ice. Anything warmer slows or halts ice formation entirely.
- Set your freezer thermostat to 0°F using an appliance thermometer for accuracy—built-in dials can drift.
- Keep the freezer door closed as much as possible; a door left open for 30 seconds can raise internal temperature by several degrees.
- Check that food isn't blocking the freezer vents. Blocked airflow creates warm spots near the ice maker.
A common mistake is setting the thermostat colder thinking it helps. Below -10°F, the ice maker's water valve can freeze, actually stopping production. Stick to the recommended range.
Water Supply Blockages
Your ice maker needs a steady, clean water supply. Blockages typically occur in two places:
- The water inlet valve: This small solenoid valve opens to let water into the ice mold. Hard water mineral deposits or debris can prevent it from opening fully.
- The water supply line: Kinks, ice jams, or sediment buildup restrict flow. Inspect the line behind and under the refrigerator for visible damage or freezing.
If your refrigerator dispenses water but makes no ice, the problem is almost certainly in the ice maker's water path, not the main water supply.
Mechanical Failures
Mechanical parts wear out over time. Common failures include:
- Ice maker motor: Should hum during the cycle. Silent? The motor may be burned out.
- Ejector arm: Should rotate freely. If stuck or grinding, gears are likely stripped.
- Temperature sensor: Tells the control board when ice is frozen. A faulty sensor prevents the cycle from advancing.
Listen for unusual noises—clicking, grinding, or complete silence—when the ice maker should be cycling. These sounds tell you which component is failing.
Quick Power Reset: The First Thing to Try
A power reset clears minor electronic glitches that stop the ice maker's control board from working correctly. This fix requires no tools and takes two minutes.
Step 1: Unplug the Refrigerator
Pull the refrigerator plug from the wall outlet. Do not simply flip the circuit breaker—a full power disconnect ensures the control board fully discharges.
Step 2: Wait at Least One Minute
Sixty seconds allows capacitors in the control board to drain completely. Waiting only 10–15 seconds may not be enough for a full reset.
Step 3: Plug Back In and Wait
Reconnect power. The ice maker should automatically begin a new cycle within 5–10 minutes. You'll hear water fill the tray and the ejector arm move.
If nothing happens after 15 minutes, press the test button (described below) to manually trigger a cycle.
Using the Reset Button for a Quick Fix
Many Wrs588Fihz00 owners don't know their ice maker has a hidden reset button. This button forces the ice maker to run a complete test cycle, clearing logic errors.
Finding the Button
Open the freezer door and remove the ice bin. Look on the front or side of the ice maker module for a small button labeled "Test" or "Reset." On some models, it's recessed and requires a pen tip to press.
The Correct Press-and-Hold Technique
Press and hold the button for 10 seconds. You should hear a single click or beep. Release immediately—holding too long on some models can lock the system in test mode.
Confirming the Fix Worked
After releasing, watch for these signs within 2–3 minutes:
- The ejector arm rotates
- Water trickles into the ice tray
- The motor hums or clicks
If you see or hear none of these, the ice maker may have a hardware issue rather than a logic error.
Inspecting the Control Arm
The control arm (also called the feeler arm or shutoff arm) tells the ice maker when the bin is full. A stuck arm is one of the most overlooked causes of ice maker downtime.
Checking Arm Position
Locate the metal or plastic arm that extends into the ice bin. It should hang freely in the down position. If it's stuck in the up position, the ice maker thinks the bin is full and refuses to produce ice.
Freeing a Stuck Arm
Ice buildup often traps the arm. Clear any frost or debris around the pivot point using a soft cloth. Avoid scraping with metal tools that could damage the arm or sensor.
After cleaning, move the arm up and down several times to confirm smooth motion. If it still sticks, the pivot mechanism may be damaged and need replacement.
Checking the Water Line and Filter
A clean, unrestricted water supply is non-negotiable for ice production. Two components deserve your attention.
Identifying Clogs in the Water Line
Turn off the water supply valve behind the refrigerator before inspecting the line. Look for:
- Kinks or sharp bends that restrict flow
- Ice jams (feel along the line for hard, cold sections)
- Mineral buildup at connection points
For suspected ice jams, a hairdryer on low heat aimed at the frozen section can thaw the line. Never use a knife or sharp object that could puncture the tube.
Replacing the Water Filter
A clogged filter is the #1 reason ice makers stop producing ice while water dispensers still work. Locate your filter—typically inside the refrigerator compartment or in the base grille.
Turn off the water supply, twist the old filter counterclockwise to remove it, insert the new filter, twist clockwise until it locks, and run 2–3 gallons through the water dispenser to clear air and prime the system.
Replace filters every six months. Mark your calendar—hard water areas may need replacement every four months.
Performing a Test or Jumper Cycle
This diagnostic step forces the ice maker through a full cycle manually, helping you pinpoint exactly where it fails.
Initiating Test Mode
Locate and press the test button (same as the reset button on most models). Hold for 5 seconds until the ice maker begins moving. If your model lacks a test button, consult the manual for jumper wire positions—a temporary electrical bridge that simulates a start command.
What to Watch For
During the test cycle, observe:
- Ejector arm rotation: Should complete a full turn without stopping or grinding
- Motor sound: Smooth hum, no rattling or clicking
- Water fill: Should hear water entering the tray within 30 seconds
- Ice ejection: Frozen cubes should release cleanly
If the motor runs but no water enters, the inlet valve is likely defective. If the arm doesn't rotate, the motor or gear assembly is the problem.
Model-Specific Tips
While the Wrs588Fihz00 has its own design, it shares features with other brands. Knowing these variations saves time.
Whirlpool Variants
Whirlpool ice makers often incorporate the reset button inside the ice tray area. For models with a metal feeler arm, ensure the arm is not bent—a bent arm can contact the housing and prevent movement.
Samsung Ice Makers
Samsung units frequently need a full power reset rather than a button press. Unplug for one minute, then plug back in. Some Samsung models also have a "Force Defrost" cycle that can resolve frozen water lines faster than manual thawing.
Other Brand Considerations
- LG: Often requires holding the reset button for 18 seconds, not 10
- GE: The test button may be hidden behind a plastic cover
- Frigidaire: Water filter location varies; check the upper-right corner of the refrigerator compartment
Always consult your owner's manual for brand-specific procedures. Manuals are available online if you've misplaced yours.
Common Mistakes That Worsen Ice Maker Problems
Avoid these errors that DIY troubleshooters frequently make:
- Forcing the ejector arm when it's frozen: This snaps plastic gears. Thaw first.
- Using hot water to thaw the ice maker: Thermal shock can crack plastic components. Use room-temperature water instead.
- Replacing parts without diagnosing: A new motor won't help if the water valve is clogged. Test first, replace second.
- Ignoring the water filter: Many "broken" ice makers revive with a simple filter change.
When to Call a Professional
Some problems require a technician's tools and expertise. Know when to stop DIY and call for help.
Signs You Need Professional Service
- The ice maker produces misshapen or hollow cubes (indicates low water pressure or a failing valve)

Frequently Asked Questions
Why is my Whirlpool side-by-side refrigerator ice maker not making ice but the water dispenser works?
This almost always points to a clogged water filter or a frozen water line feeding the ice maker alone. Replace the filter first, then check the water line for ice blockages.
How do I reset the ice maker on my Whirlpool side-by-side?
Unplug the refrigerator for 1 minute, plug it back in, then press and hold the test/reset button on the ice maker for 10 seconds until you hear a click. Ensure the feeler arm is in the down position.
How do I run a test cycle on the Wrs588Fihz00?
Press and hold the test button for 5 seconds. The ice maker should begin a complete cycle. Watch for the ejector arm to rotate and water to fill the tray. If nothing happens, the unit may need replacement.
Why does my refrigerator dispense water but not ice?
A clogged water filter or frozen water line are the most common causes. Replace the filter, check the water line for kinks or ice, and verify freezer temperature is between 0°F and 5°F.
How often should I replace the water filter?
Every six months. If you have hard water, every four months. A fresh filter ensures consistent water flow to both the dispenser and ice maker.
Conclusion
A non-working Wrs588Fihz00 ice maker is usually fixable with a methodical approach. Start with the simplest solution—a power reset—then work through the control arm, water filter, and test cycle. Most problems stem from a clogged filter, stuck feeler arm, or temporary electronic glitch.
If you've worked through every step here and still have no ice, call a qualified technician. But in most cases, you'll be scooping fresh cubes within 30 minutes of starting your diagnosis. Your next cold drink is closer than you think.
