Thermador Refrigerator Water Dispenser Not Working – What to Do

Diagnose the following components and replace any broken item you discover:

1. Door Switch

The sole function of the door switch on your Thermador refrigerator is to turn off the water dispenser as the door is opened. If the door switch breaks down, you will not be able to use your water dispenser.

You have to conduct a continuity test to ascertain the working condition of the door switch. If the test result indicates that the door switch lacks continuity, get a new one.

2. Dispenser Switch

As the dispenser switches are activated, voltage is transmitted to the dispenser. If just one switch breaks down, your dispenser will stop functioning.

Test each dispenser switch for continuity using a multimeter. If the multimeter reading shows that the dispenser switches do not have continuity, go for a replacement.

3. Dispenser Control Board

All operations of the electrical components of your Thermador refrigerator water dispenser are facilitated by the dispenser control board. If the dispenser control board is faulty, all the components it controls will start malfunctioning.

Check if the dispenser control board is the cause of the dispenser problem and go for a replacement if need be.

4. Water Inlet Valve

For water to be supplied to the dispenser, the water inlet valve needs to be opened with a minimum pressure level of 20 psi. If the water pressure is not sufficient or if the valve is broken, the water will remain closed and water will not flow to the dispenser.

Use a tool known as a water pressure regulator to measure the water pressure level of the valve. If the water pressure is up to the recommended amount, test the valve for continuity. Replace the water inlet valve if the test result indicates it lacks continuity.

5. Water Tube

To begin with, a frozen water tube will not allow your dispenser to work. To know if the water tube is frozen, pull it out from the bottom of the refrigerator door and use a hairdryer to blow air through the tube. If air does not flow through the water tube, that means it is frozen and needs to be melted.

To prevent the water tube from freezing up again or becoming too warm, ensure the freezer temperature is between 0 and 10 degrees Fahrenheit.

Before you attempt to troubleshoot and fix your refrigerator water dispenser that is not working, ensure it is disconnected from the power source to avoid electrocution.

Thermador Ice Dispenser Not Working – How to Fix

If your Thermador refrigerator ice dispenser is not working, inspect the components below and fix any discovered to be defective:

1. Water Inlet Valve

To begin with, water is supplied to the ice dispenser as the electrically-controlled water inlet valve opens. If the water pressure is not up to 20 psi, water will not be allowed to flow through the valve. Similarly, water will not flow to the ice dispenser if the water inlet valve is broken.

In light of the above, ensure that the valve pressure is up to the recommended level. You can use a water pressure regulator to measure the water pressure of the valve. If the water pressure is up to 20 psi and the water inlet valve is receiving power, but water still does not get to the ice dispenser, change the water inlet valve.

2. Icemaker Assembly

The ice maker assembly is made up of the water line, fan, and water inlet valve. If none of these parts are bad and the ice maker is still not working, you have to replace the whole ice maker assembly.

3. Icemaker Module

The icemaker module is fitted with an electric motor that rotates around the ice ejector arms and dispenses ice cubes into the ice bucket from a tray. The ice cubes are released when the temperature of the thermostat attached to the icemaker tray gets to 15 degrees Fahrenheit.

Through the rotation of the motor, power is transmitted to the water inlet valve from the icemaker module so the tray can be refilled with water.

Having a defective icemaker module means ice cannot be made or dispensed. To know if the icemaker module is what is stopping the dispenser from working, ensure the bail arm is flipped down or the ON/OFF switch is toggled to the ON position, depending on your Thermador refrigerator model.

Also, ensure the ejector blades are not stuck by ice cubes. If the ejector blade is broken, consider replacing the icemaker module.

4. Door Switch

When you open the door of your Thermador refrigerator, the door switch is triggered and the ice dispenser is turned off. Your ice dispenser will not work if the door switch is faulty.

Carrying out a continuity test helps to determine if the door switch is broken and needs to be replaced.

5. Ice Level Control Board

This Thermador refrigerator detects where the ice level in the ice bucket is with the help of an infrared beam. This beam is interrupted when the ice bucket is full and the control board turns off the ice maker.

If the ice level is below the infrared beam, the icemaker is signaled to produce more ice. The icemaker will no longer produce ice if the ice level control board is faulty.

If power is getting to the ice level control board and the ice maker is still unable to produce ice, get a new ice level control board.

6. Icemaker Mold Thermostat

To begin with, the Thermador refrigerator dispenser is equipped with a mold thermostat that keeps track of the ice tray temperature. Immediately the mold thermostat gets to 20 degrees Fahrenheit, ice cubes are dispensed from the ice maker and the ice mold is refilled with water.

The ice maker will not make ice if the icemaker thermostat breaks down. That said, you can only know if the mold thermostat is due for replacement by conducting a continuity test using a multimeter.

7. Icemaker Switch

Another component to troubleshoot if your Thermador refrigerator ice dispenser is not working is the dispenser switch. To begin with, check if you inadvertently switched off the dispenser switch. If the switch is not off but the ice dispenser is not working, perform a continuity test. This test will help you to decide whether to get a new icemaker switch or not.

8. Freezer Temperature

If your freezer temperature exceeds 10 degrees Fahrenheit, the ice maker will find it difficult to produce ice. You can set the freezer temperature at a range of 0 to 5 degrees Fahrenheit, so the ice maker can produce ice quite easily.

Also, it would help if you clean the condenser and evaporator coils to remove the debris that may have accumulated on them over time. If the coils are frosted over, the defrost system will most likely fail, causing the icemaker to stop functioning. If that is the case, thaw out the coils, and the icemaker should work properly.

9. Water Filter

To begin with, if the water filter is clogged with dirt, the water flow will be restricted, causing the ice maker not to work. Pull out the water filter from the dispenser and inspect it. If the filter is clogged with dirt, replace it.

It would be a good idea to change the water filter on your dispenser at least once in six months to allow the dispenser to function well and to maintain the quality of your ice cubes. Check out the video below to learn more about replacing the water filter of your refrigerator…
