Refrigerator Water Dispenser Not Working Repair Guide
A refrigerator water dispenser is one of the most convenient features in modern kitchens. It’s frustrating when you press the lever, only to find no water flowing.
Before calling a repair technician, you can sometimes troubleshoot and resolve the issue yourself.
Here's a detailed guide to fixing a refrigerator water dispenser that isn’t working.
KEY TAKEAWAYS
- Check and disable the dispenser's child lock feature, which can prevent the water and ice dispenser from working. This is a quick and easy solution that resolves many issues.
- Investigate potential issues like a frozen water line or reservoir, a clogged water filter, or an interrupted water supply. Thaw frozen components and replace the water filter if it hasn't been changed in the last six months.
- If basic troubleshooting doesn’t work, inspect more complex parts such as the water inlet valve and the dispenser control board. If these components fail, professional diagnosis or replacement might be required.
Turn Off the Dispenser Child Lock
Check to see if the child lock feature on the dispenser is turned on. If it is, the water and ice dispenser won’t work.
Turn the child lock feature off if you find it enabled. For most fridges, you’ll need to press and hold the dispenser button marked with the lock icon label for 5 seconds.
After turning off the child lock, the water dispenser (and ice dispenser) should work again.
Check for a Frozen Water Supply Line or Frozen Water Reservoir
In the back of some refrigerator compartments, behind the crisper drawers, you’ll find a water reservoir or coiled up section of water tubing that cools down water for the water dispenser.
A frozen line or frozen reservoir can prevent the water dispenser from getting water. Check for a frozen water line or reservoir and thaw the freeze using a hair dryer on a low heat setting.
This tactic may fix the water dispenser.
Check the Water Supply
Check to see if the ice maker is getting water. Empty the ice bin into a container and store that ice in the freezer. Once the ice maker cycles a dumps a batch of ice, see if the ice mold is filled with water to make a new batch of ice or see if the ice maker dumps a second batch of ice.
If the ice maker is getting water and making ice, then you know that the water supply going to the refrigerator is okay.
If the ice maker isn’t getting water, replace the water filter if you haven’t replaced it within the last 6 months. This may restore the water supply.
If the water filter isn’t the problem, check the water supply going to the fridge using this procedure:
- Shut off the water supply cut-off valve for the refrigerator.
- Disconnect the water supply line from the back of the refrigerator.
- Place the end of the water supply line in a bucket and briefly open the water supply cut-off valve.
If water doesn’t flow from the end of the water line, have a plumber fix the water supply going to the refrigerator.
If water flows from the end of the water supply line, then you know that the house water supply for the refrigerator is okay.
Examine the Inlet Water Valve
If the water supply going to the refrigerator is okay, then unplug the fridge and check the wire harness connection on the inlet water valve.
Reconnect the inlet water valve wires if you find them loose or disconnected.
If the wire harness connection is okay, then a bad water inlet valve could be preventing the water dispenser and ice maker from getting water. Other failures such as a damaged internal wire or bad control component could keep the water inlet valve from working.
Schedule refrigerator repair service to have a technician check the water valve circuit. The tech will need to conduct a live voltage check to see if the valve is getting voltage when you press the dispenser lever. If the valve is getting voltage but not opening to supply water to the water dispenser and ice maker, then the technician will replace the water inlet valve.
If you suspect that the water valve is defective and you want to replace it yourself without further diagnosis, follow the steps in this video to install a new water inlet valve:
Replacing the inlet water valve without a full diagnosis of the problem is a risk but it may fix the water dispenser failure.
Water Dispenser Control Problems
A failed micro-switch or bad dispenser control board can prevent the water dispenser working.
When the troubleshooting steps outlined above don’t help you fix a water dispenser failure, schedule refrigerator repair service to inspect the dispenser components and find the cause of the failure.
How to know if your refrigerator water valve is bad
A service technician will check to see if the valve is getting electrical current when actuated. If the valve coil is getting current but doesn’t open, the technician will replace the water valve. This type of live voltage check isn’t safe for DIY’ers. To check the water inlet valve on your own, unplug the refrigerator and check the resistance through the water valve solenoid coil using a multimeter. The meter should typically measure 200 to 500 ohms of resistance if it’s good. If the meter measures infinite resistance, replace the water valve because it is bad.
Cost to replace a water inlet valve on a refrigerator
If you can replace the water inlet valve yourself, then all that you’ll spend is the price of the replacement part – typically between $20 and $100. If you need to have a service technician replace the valve, that repair will typically cost you between $150 and $300.
Life expectancy of a water valve
Refrigerator water valves typically last 15 to 20 years but a failure in this type of device can occur at any time.
Knowing about the different types of failures that can prevent your refrigerator water dispenser from working will help you determine the right corrective action to take.
Although you can fix some fridge water dispenser issues on your own, more complicated failures will require a visit from a technician.

Frequently Asked Questions
Why does my refrigerator water dispenser stop working even though the fridge is cooling properly?
A refrigerator can cool normally while the water dispenser fails because the two systems operate independently. Common causes include the dispenser child lock being turned on, a frozen water reservoir or supply line, a clogged water filter, or a faulty inlet water valve. Cooling issues affect the compressor, while dispenser problems are usually related to water flow or electrical controls.
How can I tell if the problem is my refrigerator or my home’s water supply?
An easy way to confirm this is by checking whether the ice maker is producing ice. If the ice maker is working, the refrigerator is receiving water from the home supply. If not, disconnect the water line from the back of the refrigerator and briefly open the shut-off valve into a bucket. No water flow indicates a household plumbing issue, while good flow points to a refrigerator component problem.
Can a frozen water line really stop the dispenser from working?
Yes. Many refrigerators use a water reservoir or coiled tubing inside the fresh food compartment to chill drinking water. If the refrigerator temperature is set too low or airflow is restricted, this tubing can freeze and block water flow. Gently thawing the line with a hair dryer on low heat often restores normal operation.
When should I call a professional instead of attempting a DIY repair?
If basic troubleshooting steps don’t restore water flow—or if the issue involves electrical testing, live voltage checks, or control boards—it’s best to call a professional. Components like inlet water valves and dispenser control boards require specialized tools and safety procedures. A Sears Home Services technician can accurately diagnose the problem and complete the repair safely and efficiently.
