# Whirlpool Wrs588fihz00 Ice Maker Not Working

If your Whirlpool Wrs588fihz00 ice maker not working has become your morning complaint, you're not alone. It's one of the most common service calls for this model as of 2026, yet most fixes take under an hour. We've combed through user reports, service manuals, and manufacturer specs to give you the real troubleshooting path.

 

Manufacturer specifications indicate that the ice maker should begin producing cubes within 24 hours of installation. Freezer temperature should sit between 0°F and 5°F, and household water pressure needs to be in the 40 to 60 psi range. Anything outside those numbers causes most WRS588FIHZ00 ice issues.

 

So before you call a technician, let's walk through a quick decision tree that pinpoints the actual culprit.

## Start Here: What Exactly Is Your Ice Maker Doing?

 

The first step is always observation. Don't guess or start swapping parts. Open your freezer and watch what happens over ten minutes.

 

Is it silent as a tomb? Does it hum and click but never drop cubes? Are the cubes small and hollow?

 

Or does the water dispenser work fine while the ice maker sits still?

 

Each symptom points to a different failure. This table gives you the road map:

 

| Symptom | Likely culprit | Where to look |
| --- | --- | --- |
| Totally silent | Power, door switch, module | Branch 1 |
| Small or hollow cubes | Water filter, pressure, fill tube | Branch 2 |
| Runs but cubes won't drop | Thermostat, heater, bin sensor | Branch 3 |
| Water dispenser works, no ice | Ice maker module or shutoff arm | Branch 4 |

 

Before diving in, check two things. First, make sure the freezer is fully closed, since an open drawer cuts power to the ice maker. Second, if you recently changed the filter or installed the fridge, give it a full 24 hours.

 

Real faults usually show up long after that break-in period.

 

## Branch 1: The Ice Maker Is Totally Silent (No Motor, No Fill)

 

A completely silent ice maker means the control module isn't getting power, or the module itself is dead. Start with the obvious.

 

Check the shutoff arm. On this Whirlpool model, the arm sits inside the freezer and acts as an on/off switch. If it's stuck in the up position, the ice maker won't run.

 

Gently push it down. Wait for a click. The motor should start within a few seconds.

 

Next, test the door switch. The switch is mounted at the top of the freezer opening, where the drawer seals shut. If it's misaligned, the system thinks the door is open.

 

Press the switch manually and listen for a click.

Now run the test mode. Disconnect the ice maker from the freezer drawer connection, or use the test button typically located on the module's front or bottom. Hold it for a few seconds.

 

The motor should rotate and trigger a water fill.

 

If nothing happens, the module is likely fried. A power surge is the usual suspect. Unplug the fridge for five minutes, plug it back in, and retry.

 

If it still stays silent, you'll need a new ice maker assembly. Check the model number on the module and order an OEM replacement directly from [Whirlpool](https://www.whirlpool.com).

 

## Branch 2: Ice Maker Runs but Cubes Are Small or Hollow

 

Small, thin, or hollow cubes mean the ice maker isn't getting enough water. That's almost always a water delivery issue, not an ice maker issue.

 

Start with the water filter. It's located in the upper right corner of the fridge compartment. Whirlpool recommends replacing it every six months.

 

After about six months, a clogged filter restricts flow, and your cubes shrink.

 

If your filter is older, swap it out. Then press the dispenser for a minute to purge trapped air.

Check the household water pressure. A lazy stream from the dispenser means pressure is low, especially below 40 psi. Many homes dip down in summer when irrigation increases.

 

Test a faucet in the kitchen. If it's weak, the problem is house-wide. If the dispenser stream is strong, move to the fill tube.

 

The fill tube runs from the back of the refrigerator up into the ice maker mold. Over time, frost can block the tube. Remove the ice bin and inspect the tube opening for ice buildup.

 

A hairdryer on low heat works well to clear it. Never use boiling water. It can crack the plastic fill shield.

 

After clearing, reassemble and run a test fill cycle. Full cubes usually return within a few cycles.

 

## Branch 3: Ice Maker Runs but Cubes Won't Drop

 

You hear clicking, maybe a buzzing sound. The motor tries to eject, but cubes stay stuck. This is different from a silent failure, so focus on the mold and ejector assembly.

 

First, check for ice bridging. If the bin overflows or cubes clump together, they jam under the ejector blades. Remove the bin, dump the clumps, and spin the ejector blades by hand to see if they move freely.

 

Next, check the mold temperature. The ice maker heater warms the mold slightly to release cubes. If the heater fails, cubes freeze onto the metal.

 

A common test is to run the test mode and watch the ejection cycle. If you see condensation or frost only on the mold sides, the heater may be dead. You can test the mold thermostat with a multimeter.

 

It should show continuity at around 14°F.

 

If it fails at room temperature, replace the thermostat or the entire module.

 

Another culprit is the bin fill switch inside the mold. Some models have a small arm or wire that senses ice level. If it's bent, it may think the bin is full even when it's empty.

 

Push it inward gently. The ice maker should start a harvest cycle within 15 minutes. If the issue persists, the module's control board is likely the culprit.

 

Replacement is straightforward and takes about a half hour.

 

## Branch 4: Water Dispenser Works but No Ice

 

This is the good news branch. If cold water comes out of the dispenser, your water line, inlet valve, and pressure are all fine. That means the fault sits between the module and the ice maker itself.

 

Start with the shutoff arm again, but this time listen. A bent or stuck arm can keep the microswitch open, halting ice production.

 

Push the ice maker's test button to bypass the switch. If the motor runs in test mode, the switch is the problem. Adjust the arm gently back into place.

 

Next, inspect the wiring harness. The small connector between the ice maker and the refrigerator can vibrate loose. Unplug it, check for bent pins or corrosion, and reconnect.

 

A flaky connection often cuts power intermittently, showing up as a dead ice maker while the water works perfectly.

 

Run a few test cycles. If the mold fills but never freezes, confirm the freezer temperature again. It should ride around 0°F to 5°F.

 

Warmer freezers delay ice making but shouldn't stop it entirely.

 

If everything else checks out, the control board on the ice maker itself is the last link. Replacing the complete ice maker assembly, usually $60 to $90, solves the problem in most of these cases.

 

## Frequently Asked Questions

 

### How do I reset my Whirlpool WRS588FIHZ00 ice maker?

 

Disconnect power to the refrigerator for five minutes. Plug it back in and wait for the freezer to reach temperature. Push the ice maker test button.

 

This clears glitches in the control module that can stop the ice maker cold.

 

### Why is my Whirlpool ice maker not getting water?

 

A clogged water filter is the top cause. Replace it every six months. Low household pressure below 40 psi also stops flow.

 

Frost in the fill tube can block the water too. Check each in order.

 

### Can a frozen water line cause no ice?

 

Yes, if the water line running to the refrigerator freezes, no water reaches the ice maker. This happens in unheated garages or during extreme cold. Let the fridge sit at room temperature for 24 hours to thaw the line.

 

### How long does it take for a Whirlpool ice maker to start making ice?

 

After installation or a filter change, the first batch takes up to 24 hours. The freezer must reach 0°F to 5°F first. After that, most models produce about ten cubes per hour.

 

### Why does my ice maker make ice but the dispenser won't drop it?

 

Ice clumping in the bin or a stuck auger motor usually causes this. Remove the bin and break up clumps. If the auger still won't turn, the dispenser motor or control board may need replacement.

 

### What is the test mode on a Whirlpool ice maker?

 

The test mode forces a complete harvest and fill cycle in about two minutes. Locate the small button on the ice maker module or the wire harness connector. Hold it for three to five seconds.

 

The mold heats, rotates, and fills with water.

 

## Your Final Decision: DIY Repair vs. Professional Service

 

Most WRS588FIHZ00 ice maker problems fall into a few clear categories. Each has a clear next step.

 

| Scenario | Best action | Time required |
| --- | --- | --- |
| Clogged filter or frozen fill tube | DIY | 15 to 30 minutes |
| Dead ice maker module or thermostat | DIY (part swap) | 30 to 60 minutes |
| Failed water inlet valve | Professional or skilled DIY | 1 to 2 hours |
| Low house water pressure | Plumber | Varies |

 

If you are comfortable with a multimeter and basic hand tools, the ice maker module replacement is straightforward. Unplug the fridge. Remove the ice maker shroud.

 

Disconnect the harness.

 

Unscrew the two mounting screws. Install the new assembly. Reconnect and test.

 

Call a professional if you see water leaking behind the refrigerator, hear buzzing from the inlet valve, or feel uncomfortable working with electrical components. A service call usually runs between $150 and $250. It saves the risk of damaging the refrigerator's control board or water line.

 

For the vast majority of cases, following the branches in this guide gets ice flowing again. Start with the cheapest fix. The filter, the test button, and the shutoff arm cost nothing.

 

Replace parts only after confirming the fault.

 

Your Whirlpool WRS588FIHZ00 ice maker is a solid unit. Throw the right fix at it, and you will be back to full cubes before you know it.
