Whirlpool WRF535SWHZ07 Ice Maker Not Making Ice? Causes & Fixes

A Whirlpool WRF535SWHZ07 refrigerator ice maker not making ice is most often caused by the freezer running too warm, the ice maker being switched off, or a clogged water filter restricting supply, all of which can be checked in a few minutes without tools. If those check out fine, the cause is usually a frozen fill tube or a failed ice maker module, both fixable at home with basic tools. If you determine that a component needs replacement, you can browse compatible Whirlpool refrigerator parts and verify the correct fit using your refrigerator model number.

Why Is My Whirlpool WRF535SWHZ07 Refrigerator Ice Maker Not Making Ice?

1. Freezer Running Too Warm

The ice maker won't cycle unless the freezer is at or below about 10 to 15 degrees Fahrenheit. If the freezer is running warmer than that, whether from a door left open, overloading, or a cooling issue elsewhere, the ice maker simply won't produce ice until the temperature drops.

2. Ice Maker Switched Off

This model has an on/off control on the ice maker itself. It's easy to accidentally switch it off while loading or rearranging items in the freezer, making this one of the fastest causes to rule out.

3. Clogged Water Filter or Low Water Supply

A water filter that's overdue for replacement can restrict flow to the point where the ice maker can't fill properly. This usually shows up alongside a slow water dispenser, since both draw from the same water supply. Before moving on to more complex repairs, check whether your refrigerator needs a replacement filter from our selection of refrigerator water filters. If slow water flow continues after replacing the filter, other Whirlpool water dispenser parts may also need inspection.

4. Frozen or Blocked Fill Tube

The small tube that fills the ice maker mold can freeze shut, especially if the freezer has experienced a temperature swing. You'll often hear the ice maker cycle and click without any water entering the mold or any new ice being produced.

5. Failed Ice Maker Module

If the freezer is cold enough, the ice maker is switched on, the water supply is fine, and the fill tube isn't frozen, the ice maker's internal module or motor has likely failed. This is the least common cause, and the one most likely to require a replacement component. Once the other causes have been ruled out, browse available ice maker replacement parts and assemblies and confirm compatibility with the WRF535SWHZ07 before ordering.

How to Fix a Whirlpool WRF535SWHZ07 Refrigerator Ice Maker That's Not Making Ice

Tools You'll Need

• Flashlight

• Hair dryer or warm water, for thawing a frozen fill tube

• Replacement water filter, if overdue

• Replacement ice maker assembly, if needed

Safety Notes

Unplug the refrigerator or shut off the breaker before removing the ice maker housing or accessing internal components. Never use a sharp tool to chip away ice near the fill tube or ice maker, as it can puncture tubing or damage the wiring harness.

Symptom Lookup

Fix 1: Check the Freezer Temperature

Use an appliance thermometer to confirm the freezer is at or below 10 to 15 degrees Fahrenheit. If it's running warmer, address the cooling issue first. The ice maker may not resume production until the freezer temperature returns to the proper range.

Fix 2: Check the Ice Maker Switch

Confirm that the ice maker's on/off control is in the correct operating position. If it was accidentally switched off, turn it back on and allow the refrigerator time to resume the normal ice-making cycle.

Fix 3: Replace the Water Filter

If the filter hasn't been changed in the last six months or the water dispenser is running unusually slowly, replace the filter. Run several cycles of water through the dispenser afterward to clear any trapped air from the line before checking ice production again.

Fix 4: Thaw the Fill Tube

Locate the fill tube leading into the ice maker mold. Gently warm it with a hair dryer on low heat or use a warm, damp cloth until any ice inside melts. Avoid direct high heat, which can warp the plastic tubing or damage surrounding components.

Fix 5: Replace the Ice Maker Assembly

If everything above checks out and the ice maker still won't produce ice, the ice maker assembly itself may have failed. Disconnect power, remove the mounting screws holding the old assembly in place, carefully disconnect the wiring harness, and install a compatible replacement.

1. Disconnect power from the refrigerator.

2. Remove the ice bin and access the ice maker assembly.

3. Remove the mounting screws securing the old assembly.

4. Disconnect the wiring harness carefully.

5. Install the compatible replacement assembly and reconnect the wiring harness.

6. Restore power and allow the refrigerator sufficient time to resume normal ice production.
