Whirlpool Model Wrx735Sdbm00 Refrigerator Ice Maker Not Working

ByJim Boslice Home & Kitchen

If your ice maker has stopped producing, first check the wire shut-off arm or digital control settings to ensure it hasn’t been accidentally turned off. A common fix involves checking the water inlet valve, resetting the control board, or clearing a frozen ice chute.

It is incredibly frustrating when you reach for a cold glass of water on a hot afternoon, only to find the ice bin empty. You expect your high-end appliance to just work, but mechanical components eventually wear down or freeze up.

Dealing with a whirlpool model wrx735sdbm00 refrigerator ice maker not working issue is a rite of passage for many homeowners. Instead of calling a high-priced repair technician, you can often solve this with a few basic tools and a bit of patience.

In this guide, I will walk you through the diagnostic process. We will look at water supply issues, sensor malfunctions, and the common blockages that stop your ice production in its tracks.

Understanding the whirlpool model wrx735sdbm00 refrigerator ice maker not working issue

When you face a whirlpool model wrx735sdbm00 refrigerator ice maker not working scenario, the first step is to avoid panic. Most of these systems are modular and rely on a sequence of events: water flow, freezing, harvesting, and dispensing.

If one link in that chain breaks, the whole process halts. Before you start pulling panels off, verify that your kitchen water supply is actually turned on at the shut-off valve behind the unit.

Sometimes the problem is as simple as a low-pressure water line or a clogged filter. Always start with the easiest, non-invasive checks before moving to electrical testing.

Checking the basics and water supply

Before diving into the complex electronics, verify that the ice maker is actually in the “On” position. On this specific Whirlpool model, the control panel should indicate if the feature is enabled.

Inspect the water filter

A clogged water filter is the most common culprit for restricted water flow. If the filter hasn’t been changed in over six months, sediment buildup can block the path to the ice mold.

Swap out the old filter for a new, manufacturer-approved one. Run a few gallons of water through the dispenser afterward to bleed any trapped air out of the lines.

Examine the water inlet valve

The water inlet valve is an electromechanical component that opens when the control board sends a signal. If you hear a humming sound but no water enters the tray, the valve solenoid might be dead.

You can test this with a multimeter by checking for continuity. If it shows no reading, it is time to order a replacement part.

Troubleshooting the ice mold and sensor

If water is reaching the unit but nothing is happening, the issue likely lies within the ice maker assembly itself. The internal temperature of the freezer must be low enough for the thermostat to trigger the harvest cycle.

Clear the ice chute

Sometimes, a small piece of ice gets stuck in the delivery chute. This creates a bridge that prevents new ice from falling into the bin.

Use a warm, damp cloth or a hair dryer on a low setting to melt any obstructions near the mold. Be very careful not to apply direct heat to plastic parts, as they can warp or melt easily.

Resetting the control board

Modern refrigerators are essentially computers that keep your food cold. Sometimes the logic board gets stuck in a loop and needs a hard reset.

Unplug your refrigerator from the wall outlet for at least five minutes. This power cycle can often clear minor software glitches and reset the ice maker’s internal cycle.

When to replace the ice maker assembly

If you have verified the water pressure, cleaned the chute, and reset the power, yet the machine remains dormant, the motor or the sensor module may have failed.

Identifying mechanical failure

You might notice the ejector fingers are stuck in the middle of a rotation. If they do not move even after a reset, the motor has likely stripped its internal gears.

In these cases, replacing the entire ice maker unit is usually more cost-effective than trying to repair individual internal components. It is a straightforward swap that requires only a few screws.

Safety practices for the DIY repairer

Working on your appliances requires a safety-first mindset. Always disconnect the power before you touch any electrical connections, especially around the water valve.

Essential tools for your workshop

You do not need a massive tool chest for this project. Keep these items on hand:

  • A 1/4-inch nut driver for panel screws.
  • A basic multimeter for testing voltage and continuity.
  • A pair of needle-nose pliers for maneuvering small clips.
  • A clean, dry towel to catch any residual water.

Always keep your work area dry. If you are working on the floor, consider using a rubber mat to prevent slipping, especially if you have spilled any water during the troubleshooting phase.

Frequently Asked Questions About Appliance Repair

How do I know if my ice maker is frozen solid?

If you look inside the ice maker and see a block of solid ice covering the mold or the sensor, it is frozen. You can use a hair dryer on a low setting to gently melt the ice, but never use a sharp metal tool to chip it away, as you might puncture the evaporator coils.

Why is my ice coming out in small, hollow cubes?

This usually indicates low water pressure or a partially clogged water filter. The mold isn’t filling completely, resulting in thin, brittle ice. Check your water line for kinks behind the fridge and replace your filter.

Can I fix the whirlpool model wrx735sdbm00 refrigerator ice maker not working if I have no experience?

Yes, this is a very approachable DIY project. As long as you are comfortable using a screwdriver and following a sequence of steps, you can save yourself a significant amount of money on service calls by handling the basics yourself.

What if the ice maker is leaking?

Leaking is often caused by a failing inlet valve or a crack in the plastic fill tube. Inspect the connections at the back of the fridge for moisture. If the tube is cracked, it must be replaced to prevent water damage to your flooring.

Final thoughts for the garage tinkerer

Repairing your own appliances is one of the most rewarding ways to master your home. Not only do you save money, but you also gain a deeper understanding of how the machines in your house operate.

Don’t be afraid to take your time. If you feel overwhelmed, step away, grab a coffee, and revisit the manual or this guide.

Most repair issues are just puzzles waiting to be solved. Stay organized, keep your hardware in a small tray, and take photos of the wiring before you disconnect anything. You have the skills to get that ice flowing again!
