When your Whirlpool WRX735SDBM00 ice maker stops working, it can quickly become a big problem. No ice for drinks, food storage becomes harder, and you start to worry about possible repairs or expensive service calls. The good news? Many ice maker issues are easy to fix at home, especially if you understand how this model works and what usually goes wrong. In this guide, you’ll learn step-by-step troubleshooting for the most common problems, practical tips to get your ice maker running again, and advice to help you avoid future breakdowns.
Understanding how your Whirlpool WRX735SDBM00 ice maker functions is key. This refrigerator uses an automatic system that fills, freezes, and drops ice cubes into a storage bin. When something goes wrong, it’s usually due to water supply issues, temperature settings, mechanical failures, or simple user errors. By following this troubleshooting guide, you can often solve problems without calling a technician.
How The Whirlpool Wrx735sdbm00 Ice Maker Works
Before you start fixing problems, it helps to know the basic operation of your ice maker. This model uses an electronic ice maker with the following main parts:
- Water Inlet Valve: Controls water flow into the ice tray.
- Ice Mold Thermostat: Monitors freezing and starts the harvest cycle.
- Motor Module: Moves the ice ejector arms.
- Ice Bin Switch: Detects if the bin is full.
- Control Board: Manages timing and cycles.
When you ask for ice, the machine checks the bin, makes ice if needed, and drops cubes into the tray. Any part failing can stop the process.
Ice Making Cycle
- Water fills the tray.
- Water freezes.
- Motor turns ejector arms, pushing ice into the bin.
- Cycle repeats until the bin is full.
Understanding these steps helps you find where things go wrong.
Common Ice Maker Problems In The Wrx735sdbm00
Most ice maker failures fall into a few categories. Here are the most common issues Whirlpool WRX735SDBM00 owners face:
- No ice production (the most frequent problem)
- Ice maker not dispensing
- Ice cubes are too small or hollow
- Ice tastes bad or smells
- Leaking water inside freezer
- Ice maker is noisy
- Ice clumping in bin
Let’s look at each problem, why it happens, and how to fix it.

No Ice Production
When your ice maker is not making ice, start with these step-by-step checks:
1. Check The Ice Maker Switch
The WRX735SDBM00 has a power switch for the ice maker, usually located on the side or under the ice maker. Make sure it’s ON. Sometimes, this switch is accidentally turned off during cleaning.
2. Confirm Water Supply
- Check the water line behind your fridge. It should be connected and not kinked or pinched.
- Turn the water valve fully open.
- Inspect the water filter—a clogged filter can stop water flow. Replace the filter if it’s older than 6 months or the indicator light is on.
3. Freezer Temperature
Your ice maker needs a freezer temperature between 0°F and 5°F (-18°C to -15°C). If it’s too warm, ice won’t form. Use a thermometer to check. Adjust settings if needed and wait 24 hours.
4. Ice Maker Arm Position
Some models have a shut-off arm that stops ice production when the bin is full. Make sure the arm is down. If it’s stuck up, gently lower it.
5. Door Seals
If the freezer door does not seal properly, warm air enters, melting ice and preventing new cubes. Inspect the door gasket for cracks or dirt. Clean with warm soapy water and replace if damaged.
6. Reset The Ice Maker
Sometimes, resetting the ice maker solves electronic glitches. Here’s how:
- Turn the ice maker off, wait 5 minutes, then turn it back on.
- You can also unplug the refrigerator for 1 minute.
If none of these steps help, continue to deeper troubleshooting.
Ice Maker Not Dispensing
If you have ice in the bin but nothing comes out when you press the dispenser, try these solutions:
1. Ice Clumps
Ice can stick together if it sits for a long time or if the freezer is too warm. Break up clumps with a plastic utensil. Do not use metal tools, which can damage the bin.
2. Dispenser Motor
Listen for a humming sound when you push the dispenser lever. If you hear a hum but no ice moves, the dispenser motor may be jammed or faulty.
3. Dispenser Chute Blockage
Sometimes ice or frost blocks the chute. Check for obstructions and remove any buildup.
4. Auger Issues
Inside the bin, a rotating auger pushes ice toward the dispenser. If it’s frozen or stuck, remove the bin and check for ice jams. If the auger motor is bad, it may need replacing.
Ice Cubes Are Too Small Or Hollow
Small or hollow ice cubes often mean a low water flow problem.
1. Water Filter
A clogged filter restricts water. Replace with a Whirlpool-approved filter.
2. Water Pressure
Your refrigerator needs at least 30 psi water pressure. Test at the supply line by filling a quart container in under 7 seconds. If it takes longer, increase water pressure or check for blockages.
3. Inlet Valve
The water inlet valve can fail or clog with mineral deposits. If you hear buzzing but little water flows into the tray, the valve may need replacement. This job often requires a technician.
Ice Tastes Bad Or Smells
Unpleasant ice usually comes from contaminated water or dirty fridge interiors.
1. Replace Water Filter
Change the filter every 6 months or sooner if taste problems occur.
2. Clean Ice Bin
Wash the ice bin monthly with warm water and mild detergent. Rinse well.
3. Remove Old Ice
If ice sits too long, it absorbs odors. Dump old ice regularly.
4. Clean Freezer Interior
Wipe the freezer with a mixture of water and baking soda. Remove any spoiled food items.
5. Check Water Quality
If your tap water tastes bad, the ice will too. Consider using an in-line water filter.
Leaking Water Inside Freezer
Water leaks can cause ice buildup, puddles, or frozen sheets under the bin.
1. Ice Maker Tray Overflow
If the tray overfills, the inlet valve may be faulty. Replace if needed.
2. Blocked Drain
Some water drains out during the ice cycle. If the drain is blocked by ice or debris, water backs up and leaks. Clear the drain with warm water.
3. Freezer Temperature Too Low
If the freezer is much colder than 0°F, water can freeze before entering the tray, leading to leaks and ice sheets.
Ice Maker Is Noisy
Some noise is normal, but loud grinding, clicking, or banging can signal problems.
1. Harvest Cycle Sounds
The motor makes noise as it pushes ice. Short clicking and whirring are normal.
2. Loud Grinding
This may mean the ejector gears are stripped or jammed. Remove the ice bin and check for obstructions. If noise continues, the motor may need repair.
3. Water Hammer
A loud bang when filling means high water pressure. Install a water hammer arrestor if needed.
Ice Clumping In Bin
Clumping happens when ice partially melts and refreezes, sticking together.
1. Door Left Open
Warm air entering the freezer melts ice. Always close the door fully.
2. Freezer Temperature Fluctuations
Keep the freezer at a steady 0°F. Avoid overloading the freezer, which can block airflow.
3. Remove Old Ice
Dump old ice to prevent clumping, especially in humid climates.
When To Call A Technician
Not all problems are DIY-friendly. Call a professional if:
- You see error codes on the display panel
- Water leaks from behind or underneath the refrigerator
- The ice maker is unresponsive after reset
- Electrical smells or visible damage appear
Some repairs, like replacing the control board or inlet valve, require special tools and knowledge.
