Common Whirlpool WRX735SDBM00 Ice Maker Problems and Fixes

1. Ice Maker Is Turned Off

If the ice bin is empty and no water enters the mold, the ice maker may simply be turned off.

Symptoms: No ice, empty ice bin, inactive ice maker, no water entering the ice mold.

Possible causes: Accidentally turned off during cleaning, filter replacement, vacation mode, or ice bin removal.

• Ice maker assembly

• Ice maker switch

• Wire harness

• Control board

2. Ice Maker Not Getting Water

If the ice maker is on but the mold stays dry, inspect the water supply path from the shutoff valve to the inlet valve.

• Check that the household water supply valve is fully open.

• Inspect the water line for kinks or bends.

• Test water dispenser flow.

• Remove and reinstall or replace the water filter.

• Inspect the water inlet valve.

3. Producing Small or Hollow Ice Cubes

Small or hollow cubes usually mean the ice maker is not receiving enough water during the fill cycle.

• Replace or reinstall a clogged water filter.

• Check household water pressure.

• Straighten kinked water lines.

• Ensure the shutoff valve is fully open.

• Inspect the inlet valve if the issue persists.

4. Ice Maker Not Dumping Ice

If the mold fills but the cubes never drop into the bin, the harvest cycle may be blocked or the ice maker assembly may be failing.

• Remove ice jams from the ejector arm.

• Reset refrigerator power.

• Check ice maker temperature and harvest cycle.

• Inspect the ice maker assembly if needed.

5. Ice Maker Frozen or Has Ice Buildup

If the ice maker area freezes up, water may be leaking slowly or warm air may be entering the compartment.

• Remove the ice bin and inspect for clumped ice.

• Clear the ice chute carefully.

• Thaw a frozen fill tube.

• Inspect the door gasket and inlet valve.

6. Ice Dispenser Not Working

If the refrigerator makes ice but will not dispense it, the issue is usually with the bin, auger, switch, or dispenser controls.

• Confirm the ice bin is seated correctly.

• Remove clumped ice.

• Clean the ice chute and dry the area.

• Test the dispenser paddle and auger motor.

• Check the dispenser switch and control board if needed.

7. Ice Maker Making Ice Slowly

Slow ice production usually points to warm temperatures, poor airflow, or restricted water flow.

• Check that the freezer temperature is cold enough.

• Keep refrigerator doors closed as much as possible.

• Ensure vents are clear for airflow.

• Replace a restricted water filter if necessary.

• Inspect the ice maker assembly if water flow and temperature are correct.

FAQs About Whirlpool WRX735SDBM00 Ice Maker

1. Why is my Whirlpool WRX735SDBM00 ice maker not making ice?

The ice maker may be turned off, the water supply valve may be closed, the water line may be kinked, or the water filter may be clogged or installed incorrectly. If those checks pass, the ice maker assembly itself may need replacement.

2. Why is my Whirlpool WRX735SDBM00 ice maker making small ice cubes?

Small or hollow cubes usually mean the ice maker is not getting enough water. Inspect the filter, water line, shutoff valve, and inlet valve to confirm good flow and pressure.

3. Why does my Whirlpool refrigerator make ice but not dispense it?

If ice is produced but not dispensed, the problem is usually the ice bin, auger motor, dispenser switch, ice chute, or dispenser door. Check the bin position and clear any clumped ice first.

4. How do I reset the Whirlpool WRX735SDBM00 ice maker?

Unplug the refrigerator for 1 minute, then plug it back in. Give the ice maker time to cycle and resume production.

5. Why is my ice maker frozen?

A frozen ice maker may be caused by a frozen fill tube, a leaking inlet valve, warm air entering through a bad door gasket, or ice buildup around the chute or bin.

6. Should I replace the water filter if the ice maker stops working?

Yes. A clogged, incompatible, or incorrectly installed filter can reduce water flow enough to stop ice production or cause small, hollow cubes.

7. Can I repair the Whirlpool WRX735SDBM00 ice maker myself?

Basic fixes like checking the switch, replacing the filter, clearing ice jams, and cleaning the ice bin are DIY-friendly. Repairs involving wiring, control boards, valves, or full assembly replacement require more care and may be better handled by a technician.

8. How do I find the right ice maker part for WRX735SDBM00?

Always search by the full model number WRX735SDBM00 to ensure compatibility for the ice maker assembly, water inlet valve, filter, bin, and dispenser components.

Final Takeaway

Start with the simple checks before replacing parts: confirm the ice maker is on, the water supply is open, the filter is installed correctly, the water line is not kinked, and the freezer is cold enough. If those checks do not solve the problem, inspect the fill tube, water inlet valve, ice bin, dispenser parts, and the ice maker assembly itself. Always use the complete model number WRX735SDBM00 when searching for compatible replacement parts.
