Maytag Refrigerator Ice Maker Not Working: Causes and DIY Fix Guide
The most common reason a Maytag ice maker stops producing ice is a frozen water fill tube. Check the freezer temperature first—if it’s below 0°F (-18°C), the water line can freeze, blocking new ice. This guide walks you through the earliest checks, safe DIY fixes, and when to call a technician.
Frozen Fill Tube: The Most Common Culprit
Open the freezer door and listen after the refrigerator’s main door closes. You should hear a faint water-fill click followed by a short hissing sound as water flows into the ice mold. If you hear nothing, the fill tube is likely frozen or the water supply valve is not opening.
Quick visual test: Remove the ice bin and look into the small fill hole at the top rear of the ice maker. If you see a thin sheet of ice or frost bridging the hole, the line is blocked. That is the failure mode many Maytag owners hit first—and it can be detected early by checking for frost accumulation around the fill hole before the ice maker stops completely. Catching it early means you can thaw the tube without replacing parts.
Likely Causes Ruled Out in 10 Minutes
Use this symptom-matched approach to narrow down the problem:
| Symptom | Most Likely Cause | DIY Difficulty |
|---|---|---|
| No ice at all, no water fill sound | Frozen fill tube or water inlet valve stuck closed | Easy to check, moderate to replace valve |
| Ice maker makes ice but very slowly | Clogged water filter or too-cold freezer | Easy |
| Ice is small, hollow, or misshapen | Low water pressure or partially frozen tube | Moderate |
| Ice maker runs but no water fills | Defective ice maker module (thermostat or motor) | Moderate to replace |
Frozen fill tube – If the freezer runs too cold (below -10°F), moisture can freeze inside the fill tube. Thaw it by unplugging the refrigerator for 4–6 hours with doors open, then restart.
Clogged water filter – A filter that hasn’t been changed in 6+ months reduces flow enough to slow or stop ice production. Replace it with a genuine Maytag filter (model varies by serial number).
Faulty ice maker module – If the freezer is at the correct temperature (0°F to 5°F) and water flows into the mold but the ice never ejects, the module’s thermostat or motor may have failed. This requires an OEM replacement part and basic electrical testing.
Check and Fix the Fill Tube, Filter, and Valve
Follow these ordered steps. After each fix, confirm the result before moving on.
Reset the Ice Maker
Most Maytag ice makers have a manual reset button or a test switch. Press and hold the button for 5 seconds until you hear a clicking sound, then release. Confirm the fix worked: Listen for a water fill click within 10 minutes. If you hear it, the ice maker should cycle and produce ice within the next 2–4 hours. If not, proceed to the next step.
A common mistake: pressing the button too quickly or not holding long enough. Confirm the button clicks fully. For additional reset guidance, see our article on how resetting helps repairing ice maker.
Thaw a Frozen Fill Tube
- Unplug the refrigerator or turn off the water valve.
- Remove the ice bin and place a towel below the fill tube.
- Point a hairdryer on low heat into the fill hole for 30–60 seconds. Do not use high heat—it can warp the plastic housing.
- Wait 10 minutes, then turn the water supply back on and listen for the fill click.
Confirm the fix worked: After 4 hours, open the freezer and look for new ice in the bin. If ice appears, the thaw was successful. If not, check the water inlet valve.

Replace the Water Filter
Locate the filter (usually in the upper-right corner of the fresh food compartment or behind the base grille). Turn it counterclockwise to remove, install the new filter, and run 2 gallons of water through the dispenser to purge air. Confirm the fix worked: Ice production should resume within 24 hours. If not, proceed to the valve test.
Test the Water Inlet Valve
With the refrigerator plugged in and the ice maker calling for water (you can hear a relay click in the back), use a multimeter on the valve coil terminals. Resistance should be between 200 and 500 ohms. If open (infinite) or shorted (0), replace the valve.
Stop signal: If you have tested all above and the ice maker still refuses to cycle, the problem is likely in the main control board or ice maker module itself. Further DIY repair is not recommended without manufacturer schematics.
When the Ice Maker Itself Needs Replacement
Escalate to a technician if:
– The ice maker module runs but the mold never heats to release ice.
– The gear motor is visibly stuck (no movement during harvest cycle).
– The freezer temperature is stable in the 0–5°F range, water pressure is good, and you have replaced the filter and valve.
Replacing the ice maker module is straightforward on many Maytag models—unplug the harness, remove two screws, and install the new module (part number available from your model’s service manual). However, if the control board is suspect, professional diagnosis saves time and avoids buying unnecessary parts. For Frigidaire models, module replacement steps differ; see troubleshooting frigidaire ice maker reset or repair for model-specific guidance.
Quick Decision Checklist for Ice Maker Not Working
| Check Item | Pass / Fail | Action if Fail |
|---|---|---|
| Freezer temp between 0°F and 5°F | □ Pass □ Fail | Adjust thermostat; wait 2 hours. |
| Water filter changed within 6 months | □ Pass □ Fail | Replace with OEM filter. |
| Fill tube clear of frost/ice | □ Pass □ Fail | Thaw with low heat (step 2 above). |
| Ice maker arm or sensor not stuck | □ Pass □ Fail | Gently free the arm; ensure no ice jam. |
| Ice maker cycles when test button pressed | □ Pass □ Fail | Replace ice maker module. |
Run through these five checks in order. If you reach the fifth item and it fails, you have isolated the module as the root cause.
Additional Diagnosis: Testing Temperature and Sensors
Maytag ice makers rely on a simple bimetal thermostat and a motor-driven gear. The thermostat closes when the ice mold reaches around 15°F, starting the harvest cycle. If the thermostat is stuck open, the ice maker will never heat the mold.
Using a multimeter, test the thermostat for continuity at room temperature (should be closed) and after placing it in a freezer (should open near 15°F). If it does not open or close at the expected range, it has drifted out of calibration.
Always unplug the refrigerator and wait at least two minutes before testing any electrical component. Capacitors can hold a charge, and touching the wrong terminal can cause injury or blow a fuse. – Maytag Usage and Care Guide (typical safety instruction)
If your ice maker still hasn’t produced ice after running these checks, a defective main control board is the last likely suspect. At that point, booking a technician with access to Maytag service bulletins is the most efficient next step.
