Refrigerator Not Cooling? The Full Diagnostic, Cause by Cause
A fridge not cooling comes down to one question: is your freezer still cold? If yes, cold air is being made but not reaching the fresh-food section. If both se…
Your Whirlpool fridge ice maker is not making ice, and in July that matters. The good news: knowing whether your water dispenser still works cuts the diagnostic list in half before you touch a single component. Start with the 60-second check below.
| Symptom | Most Likely Cause | Your Next Step |
|---|---|---|
| Ice maker was working, now nothing | Feeler arm nudged up or switch off | Push arm down; confirm switch is on |
| No ice but water dispenser works | Feeler arm, freezer temp, module, or optical sensor | Check arm, verify 0 to 5 degrees F, try reset |
| No ice and no water from dispenser | Inlet valve, clogged filter, or supply line | Check supply shutoff behind fridge, then replace filter |
| Water from dispenser is slow or weak | Clogged or expired Everydrop water filter | Replace filter and reseat it firmly |
| Ice maker clicks but mold never fills | Frozen fill tube or inlet valve failure | Inspect fill tube for ice plug; call a pro if clear |
| Ice maker runs full cycle, no ice | Freezer temperature above 10 degrees F | Thermometer overnight; target 0 to 5 degrees F |
The 60-Second Check Before You Diagnose Anything Else
Check the Feeler Arm
On most Whirlpool side-by-side and French door models, a wire arm sweeps down during each harvest cycle. When it contacts ice in the bin, it lifts and cuts power to the unit. Removing the ice bin is the most common way to knock the arm up; it stays raised and stops production with no error code.
Pull out the ice bin and look at the right side of the module. If the arm is raised, push it down until it clicks into the lower position. Slide the bin back in firmly, then give the unit 24 hours before checking for new ice.
On Whirlpool models with an infrared sensor (the WRS571CIHZ is the most common example), a slightly misaligned bin breaks the beam and signals a full bin. Reseat it firmly and production resumes. Our technicians find the arm or sensor bin-seating issue behind roughly one in three Whirlpool ice maker stopped working calls.
Check the Ice Maker Switch
Confirm the switch is in the ON position; it is easy to nudge off during cleaning or bin removal. On side-by-side models the switch sits on the front face of the module; on French door models it may be on the side wall of the freezer compartment.
Both checks together take under a minute and cost nothing. If the arm is down and the switch is on but the Whirlpool ice maker not working problem persists, move to the water dispenser test in the next section.
When the Water Dispenser Works but the Ice Maker Does Not
When the water dispenser works and your Whirlpool fridge is not making ice, the inlet valve is not the cause. Water is reaching the refrigerator. The fault is on the ice maker side: feeler arm, temperature, fill tube, module, or optical sensor.
“When the water dispenser is still flowing and the ice maker is dead, I stop checking the valve immediately. Nine times out of ten the feeler arm is stuck or the ice bin is misaligned. Start there before replacing any parts.”
Alex Feldman, W&M Refrigeration Technician
When water stops at both the dispenser and the ice maker, the supply side is implicated: a turned-off saddle valve, a kinked line, a clogged Everydrop filter, or pressure below 20 PSI. That is a different diagnostic branch from the Whirlpool ice maker not working but water works scenario.

Six Causes a Whirlpool Ice Maker Stops Making Ice
The Ice Maker Switch and Feeler Arm
A wire arm on the right side of the module sweeps down during harvest. When it contacts ice, it raises and cuts power. Removing the ice bin is the most common way to knock it up. On optical sensor models, the bin must sit squarely in its track.
When the bin is slightly off, the board (part W10757851 on many Whirlpool models) locks into a “bin full” signal. Clear any debris from the tracks and reinsert until it clicks. A Whirlpool ice maker arm not working mechanically, whether a bent wire or a broken socket, causes identical symptoms and requires module replacement.
Freezer Temperature
Above 10 degrees F, the mold thermostat never reaches its closing temperature and the harvest cycle stops. Whirlpool specifications call for 0 to 5 degrees F. Place a thermometer in the freezer overnight to get a true reading.
A door seal that has lost its compression can raise the temperature 8 to 10 degrees without the freezer feeling obviously warm. A frozen food bag blocking the evaporator fan has the same effect. If the freezer is running warm, diagnose why before replacing the ice maker. A new module in a warm freezer fails for the same reason as the original.
See our Whirlpool refrigerator not cooling guide and the refrigerator not cooling hub for the defrost system path.
Water Filter
A clogged Everydrop filter restricts flow to the ice maker mold. The unit may still produce thin, undersized ice crescents or stop filling entirely. Whirlpool recommends replacing the filter every six months.
Denver’s water supply runs at approximately 150 mg/L total dissolved solids, moderately hard water that can shorten that interval. A new filter installed without full seating creates an air lock that starves the mold. To fix it: remove the filter, run the dispenser briefly to clear the air, then reinsert with a firm quarter-turn until it stops.
Frozen Fill Tube
An ice plug in the ice maker fill tube stops water from reaching the mold. The tube runs along the upper rear wall on in-freezer models, and through the door hinge on in-door models where a loose seal causes freeze-over.
Inspect behind the ice maker housing. A solid white plug where there should be an open channel confirms the diagnosis. Unplug the refrigerator, then use a hair dryer on its lowest setting, keeping it moving to avoid melting the plastic. A fill tube that refreezes within weeks points to a door seal problem.
See our guide on refrigerator leaking water and freezer not freezing for adjacent cold-side causes.
Water Inlet Valve
A failed inlet solenoid cuts water to both the dispenser and the ice maker at the same time. This electrically-controlled valve opens to supply water on demand. On dual-solenoid models, only the ice maker solenoid may fail while the dispenser keeps working.
Testing requires a multimeter with the refrigerator unplugged; a healthy coil reads approximately 240 to 280 ohms. Confirm household water pressure meets the minimum 20 PSI before ordering a replacement; low pressure is a separate problem a new valve cannot fix.
Ice Maker Module or Optical Sensor
When the reset cycle runs and the ejector blades move but no water fills the mold, check the inlet valve first. When the valve tests healthy too, the ice maker module has failed. All control electronics live in the sealed module: motor, timer cam, heater, and mold thermostat. The entire unit replaces as one.
On sensor-equipped models, the receiver board can lock into a “bin full” state. Remove the bin and look for a green LED on the receiver board. A dead LED means board failure.
The board replaces independently of the full module, making it a less costly repair. Our technicians provide Whirlpool ice maker repair including optics board diagnosis across Denver Metro.
How to Reset a Whirlpool Ice Maker
Run the Whirlpool ice maker reset after completing the arm and switch checks.
- Locate the reset button on the bottom of the module (in-door models: underside of the unit). No button? Flip the power switch OFF, wait five minutes, then flip it ON.
- Press and hold for 3 to 10 seconds until you hear a beep or feel the motor begin to cycle.
- Watch the cycle. The motor runs, ejector blades rotate, water fills the mold near the end. No water fill? Inlet valve or fill tube is next. Motor stalls? The module has likely failed.
- Wait 24 hours. The first batch freezes at 0 to 5 degrees F; give the unit a full day before concluding it did not work.
After a power outage, unplug the refrigerator for five minutes, then plug back in and wait 24 hours before judging results.
Whirlpool Model-Specific Ice Maker Notes
Every Whirlpool refrigerator ice maker runs in one of two configurations: in-freezer or in-door. The WRX735SDBM runs both simultaneously as a dual ice system; on that model, identify which unit stopped before diagnosing.
The table below covers the six most-searched Whirlpool models for Whirlpool appliance repair across Denver Metro. If your model is not in the table, the same diagnostic sequence applies.
| Model | Configuration | Level Sensor | Key Diagnostic Note |
|---|---|---|---|
| WRS588FIHZ | Side-by-side, in-freezer | Feeler arm | Arm knocked up when removing bin; wire harness can stretch at door hinge |
| WRQA59CNKZ | Counter-depth side-by-side, in-freezer | Feeler arm | Stuck arm; freezer temperature drift toward 10 degrees F |
| WRX735SDBM DUAL ICE MAKER | 4-door French door, in-freezer and in-door | Feeler arm (freezer) and optical sensor (door) | Identify which unit stopped; in-door unit more prone to optics board failure and door hinge water line freeze |
| WRF555SDFZ | French door, in-freezer | Feeler arm | Fill tube freeze is common; module failure is also a top cause on this model |
| WRS325SDHZ | Side-by-side (Whirlpool Gold series), in-freezer | Feeler arm | Classic stuck arm; Denver hard water accelerates filter clogging |
| WRS571CIHZ | Side-by-side, in-freezer | Optical sensor (infrared) | Optics board W10757851 failure; bin misalignment blocking the IR beam |
When to Call an Appliance Technician
Signs You Need a Pro
The arm check, filter replacement, and fill tube thaw are DIY-accessible. The water inlet valve, ice maker module, and optics board require a multimeter and electrical safety discipline. Guessing wrong costs a second labor visit and more days without ice.
Book a technician when the reset cycle completes but no water fills the mold. A stalled cycle with the motor running and no blade movement also points to module failure. Call when freezer temperature is correct, the filter is fresh, and the Whirlpool ice maker not working problem still does not resolve after 24 hours.
Our fridge repair service covers both Whirlpool configurations across Denver Metro. If the ice maker stopped when July heat started, a technician can diagnose the cause on-site and schedule the repair so you have ice again before the weekend.
Frequently Asked Questions
Why Is My Whirlpool Ice Maker Not Working?
Six causes account for nearly all Whirlpool ice maker failures. The list: feeler arm stuck up, freezer above 10 degrees F, clogged Everydrop filter, frozen fill tube, failed inlet valve solenoid, or failed ice maker module or optics board.
Whether you call it Whirlpool refrigerator ice maker not working or ice maker not working Whirlpool, the diagnostic path is the same. Does the water dispenser still work? That one question splits the list in half.
How to Reset a Whirlpool Ice Maker
Press and hold the small rectangular button on the bottom of the module for 3 to 10 seconds until you hear a beep or feel the motor start. That is how to reset Whirlpool ice maker on most models. Wait 24 hours for the first batch.
No button on your model? Flip the ice maker switch OFF for five minutes, then ON. Whirlpool freezer not making ice after a power outage? Unplug for five minutes first.
Whirlpool Ice Maker Not Working but Water Works
When the water dispenser works normally, the water inlet valve is almost certainly not the cause. Water is reaching the refrigerator. Check the arm first (30 seconds), then verify freezer temperature is between 0 and 5 degrees F.
If both check out, work through the fill tube, ice maker module, and the sensor on sensor-equipped models.
Ice Maker Not Working on Whirlpool Refrigerator
A Whirlpool side by side refrigerator ice maker not working most often traces to the wire arm or switch. Whirlpool side by side ice maker not working? Same diagnosis. A Whirlpool in door ice maker not working more often points to an optics board or door hinge freeze.
A Whirlpool French door refrigerator ice maker not working, Whirlpool bottom freezer ice maker not working, and Whirlpool 4 door refrigerator ice maker not working all follow the same checks. Whirlpool Gold ice maker not working uses the same procedure; Whirlpool Gold series is a marketing tier, not a different platform.
Why Is My Ice Maker Not Making Ice?
Start with freezer temperature. An ice maker stops cycling above 10 degrees F because the mold thermostat never closes. Whirlpool specifies 0 to 5 degrees F.
Whirlpool refrigerator not making ice, Whirlpool fridge not making ice, Whirlpool fridge ice maker not working, Whirlpool ice maker not making ice: all four describe the same failure. The fix sequence is the same: check the arm first, then the Everydrop filter, fill tube, and water inlet valve.
How Do I Know If My Whirlpool Ice Maker Is Broken or Just Off?
Press and hold the reset button for 3 to 10 seconds. If the motor runs, the ejector blades cycle, and water fills the mold at the end of the test cycle, the module is mechanically intact.
If nothing happens after confirming the switch is on and the arm is down, the module is likely failed and needs Whirlpool ice maker replacement.
