Common Ice Maker Issues
Thermador ice makers can face common issues that stop them from working properly. These problems often affect ice production and quality. Knowing what causes these issues helps fix them faster. Below are some typical problems that may cause your ice maker to stop working.
Ice Maker Switch Off
Sometimes the ice maker switch is turned off by mistake. This stops ice production completely. Check the switch or button on the control panel. Make sure it is set to “On” or the ice maker function is enabled. A simple toggle can restart ice making.
Clogged Water Filter
A dirty or clogged water filter blocks water flow to the ice maker. This reduces ice output or stops it entirely. Replace the water filter every six months or as recommended. A clean filter ensures fresh water reaches the ice maker smoothly.
Water Supply Problems
Ice makers need a steady water supply to work well. Check that the water line is connected and not kinked or frozen. Low water pressure can also cause problems. Fix any leaks or blockages in the water supply line to restore ice making.
Ice Blockages
Ice can get stuck inside the ice maker or dispenser chute. This blocks new ice from coming out. Remove the ice bin and clear any ice jams. Make sure the ice bin is seated correctly to prevent blockages. Regularly check for and clear ice buildup.
Simple Reset Methods
Simple reset methods can often fix your Thermador ice maker quickly. These easy steps help restart the system and clear minor glitches. Trying these resets first can save time and avoid costly repairs. Follow the instructions carefully to ensure success.
Unplug And Restart
First, unplug the refrigerator from the power outlet. Wait for about five minutes to let the system reset completely. Then, plug it back in and wait for a couple of hours. The ice maker should start making ice again during this time.
Control Panel Reset
Open the refrigerator control panel and find the settings or menu option. Look for “Ice Maker Reset” or “Reset Water Filter.” Some models need you to press and hold two buttons like SETUP and ICE for three seconds. This will reset the ice maker and help it work normally.
Using Reset Switch
Locate the ice maker inside the freezer. Find a small reset switch on the ice maker or near the control panel. Press and hold this switch for a few seconds. This action triggers a new ice-making cycle. Wait a few hours for ice production to resume.
Inspecting Water Supply
Inspecting the water supply is a crucial step when your Thermador ice maker stops working. The ice maker depends on a steady flow of water to produce ice cubes. Any interruption or problem in the water line can cause the ice maker to fail. This section explains how to check the water supply and fix common issues.
Check Water Inlet Valve
The water inlet valve controls water flow to the ice maker. Start by unplugging the refrigerator for safety. Locate the valve, usually at the back near the bottom. Inspect it for any signs of damage or leaks. Test the valve with a multimeter to ensure it has power. Replace the valve if it does not open when powered. A faulty valve stops water from reaching the ice maker.
Examine Water Pressure
Water pressure affects how well the ice maker fills with water. The pressure should be between 20 and 120 psi. Low pressure causes slow or no ice production. Use a pressure gauge to measure water pressure at the valve. Check your home’s main water supply and shut-off valve for issues. Increase pressure or call a plumber if pressure is too low.
Look For Kinks Or Blockages
Water lines can get bent or clogged, blocking water flow. Inspect the tubing from the water supply to the ice maker. Straighten any kinks or bends carefully. Flush the line to remove any debris or mineral buildup. Clear any blockages found in the line or valve. Clean, smooth water flow ensures the ice maker works properly.
Clearing Ice Blockages
Ice blockages often cause a Thermador ice maker to stop working. Clearing these blockages helps restore ice production quickly. Ice can jam inside the fill tube or prevent the ice bin from fitting correctly. Fixing these issues allows the ice maker to operate smoothly again.
Remove Ice Jams In Fill Tube
Ice jams in the fill tube stop water from reaching the ice mold. Turn off the ice maker before starting. Use warm water or a hairdryer to gently melt ice inside the tube. Avoid using sharp objects that can damage the tube. Clear all ice until water flows freely again. This step often fixes common ice maker problems.
Ensure Proper Ice Bin Placement
The ice bin must sit correctly to allow ice to drop freely. Remove the bin and check for any ice clumps inside it. Clear any stuck ice pieces that block the bin’s movement. Slide the bin back fully into its place. A misaligned bin can cause the ice maker to stop working. Proper placement ensures smooth ice collection and dispensing.
Filter Maintenance
Proper filter maintenance plays a vital role in keeping your Thermador ice maker working well. A clean and fresh water filter ensures clear, good-tasting ice. It also prevents clogs and mechanical issues inside the ice maker. Neglecting filter care can cause slow ice production or no ice at all.
Regularly changing and resetting the water filter helps maintain water flow and ice quality. Follow simple steps to replace the filter and reset the filter indicator light. This keeps your Thermador ice maker running smoothly and extends its lifespan.
Replacing Water Filter
Locate the water filter inside your Thermador refrigerator or near the water inlet. Turn off the water supply to avoid leaks. Turn the old filter counterclockwise and pull it out carefully. Insert the new filter by pushing it in and turning clockwise until it locks. Turn the water supply back on. Run water for a few minutes to clear air and impurities from the new filter.
Resetting Filter Indicator
After replacing the filter, find the filter reset button on the control panel. Press and hold it for 3 to 5 seconds until the indicator light turns off. This resets the system and tracks the new filter’s usage. Some models may require pressing a combination of buttons, like “SETUP” and “ICE.” Check your Thermador manual for exact instructions. Resetting the indicator ensures you get timely reminders for the next filter change.

Thermostat And Sensor Checks
The thermostat and sensors play a key role in the Thermador ice maker’s function. These parts control temperature and detect when ice is ready. Faulty components can stop ice production completely. Checking these elements helps spot issues early and avoid costly repairs.
Testing the thermostat and inspecting sensors are simple steps. They ensure the ice maker works efficiently. Both tasks require basic tools and careful observation. Understanding these parts can save time and money on service calls.
Testing Ice Maker Thermostat
Start by locating the thermostat inside the ice maker. Use a multimeter to test its resistance. Set the multimeter to the ohms setting for accuracy. Place the probes on the thermostat terminals. A normal reading means the thermostat is working well.
No reading or infinite resistance indicates a broken thermostat. Replace it to restore proper cooling. Check that the thermostat reacts to temperature changes. It should close when cold and open when warm.
Inspecting Sensors
Sensors monitor ice level and temperature in the ice maker. Look for visible signs of damage or dirt on sensor surfaces. Clean sensors gently with a soft cloth if needed.
Test sensors using a multimeter or consult the user manual for specific steps. Faulty sensors can send wrong signals, stopping ice production. Replace any sensor that fails the test. Proper sensor function ensures smooth ice making cycles.
