Common Causes of Thermador Freezer Not Making Ice

Here are some of the most frequent reasons why your Thermador ice maker might be on the fritz:. For more related activities, check out our Kenmore Refrigerator Water Dispenser Leaking.

• Freezer Temperature Too High: If the freezer isn’t cold enough (ideally 0-5F/-18 to -15C), the ice maker won’t function correctly.
• Ice Maker is Turned Off: Sometimes the ice maker is simply switched off accidentally.
• Water Supply Issues: A kinked, frozen, or disconnected water line can prevent water from reaching the ice maker.
• Water Filter Clogged: A dirty water filter restricts water flow to the ice maker.
• Ice Jam in the Ejector: Ice can sometimes get stuck in the ice maker’s ejector arm, preventing new ice from being dispensed.
• Faulty Water Inlet Valve: This valve controls the flow of water into the ice maker. If it’s defective, it won’t let water in.
• Defective Ice Maker Module: The ice maker module controls the entire ice-making process. A faulty module needs professional diagnosis and repair.
• Door Seal Problems: A damaged or leaky door seal allows warm air to enter, affecting the freezer’s temperature and ice production.

Symptoms Checklist

Use this checklist to narrow down the potential problem:

• The freezer temperature is above 10F/-12C.
• You hear no sound coming from the ice maker.
• The ice maker is switched to the “off” position.
• There’s a noticeable decrease in water pressure to other appliances (e.g., the water dispenser).
• The water filter hasn’t been changed in the last 6 months.
• You see ice jammed in the ice maker’s ejection mechanism.
• The door doesn’t seal tightly, or the seal is damaged.

How to Fix Thermador Freezer Not Making Ice Step-by-Step Guide

1. Check the Freezer Temperature: Use a thermometer to ensure the freezer is between 0-5F/-18 to -15C. Adjust the temperature settings if necessary and allow several hours for it to reach the correct temperature.
2. Verify the Ice Maker is On: Locate the power switch or lever on the ice maker and ensure it’s in the “on” position. Consult your freezer’s manual if you’re unsure.
3. Inspect the Water Supply Line: Look behind the freezer for the water supply line. Make sure it’s not kinked, bent, or frozen. If it’s frozen, try thawing it gently with a hairdryer (on a low setting) or warm cloths.
4. Check the Water Pressure: Test the water pressure to the refrigerator. If it’s low, there might be a problem with your home’s plumbing.
5. Replace the Water Filter: Locate the water filter (usually inside the refrigerator or behind the base grille) and replace it with a new one. Refer to your owner’s manual for instructions on how to do this properly.
6. Clear Ice Jams: If you see ice stuck in the ice maker’s ejection arm, carefully remove it. You may need to use a plastic utensil to avoid damaging the mechanism.
7. Check the Water Inlet Valve: The water inlet valve is typically located at the back of the freezer. A visual inspection may be enough to determine visible damage. However, testing it requires using a multimeter, which beginners should probably avoid.
8. Inspect the Door Seal: Examine the door seal (gasket) around the freezer door. If it’s torn, cracked, or dirty, clean it thoroughly with a damp cloth and mild detergent. If it’s damaged, it will need to be replaced.
9. Reset the Freezer: Unplug the freezer for 5 minutes, then plug it back in. This can sometimes reset the ice maker and resolve minor issues.
10. Listen for the Water Valve: After resetting, listen for the sound of the water valve opening and filling the ice maker tray. If you don’t hear it, there might be an issue with the valve or the ice maker module.

Fix the Issue Without Buying Parts

Before considering replacements, try these free methods:

• Freezer Reset: As mentioned above, unplugging your freezer can sometimes resolve software glitches that prevent ice production.
• Deep Cleaning: Clean your freezer and ice maker regularly to prevent ice jams and maintain optimal performance.
• Door Seal Inspection: Regularly check and clean the door seal to ensure a tight seal.

When Replacement Might Be Necessary

If the troubleshooting steps above don’t solve the problem, you might need to replace a part. Here are some common components that can fail:

• Water Inlet Valve: If the valve isn’t opening or closing properly, it will need to be replaced. The cost can range from $50 to $150 USD.
• Ice Maker Module: If the module is faulty, it might require replacement. The cost can range from $100 to $300 USD.

Safety Warning

• Always unplug the freezer before performing any repairs or inspections.
• Avoid working on electrical components if you’re not comfortable or experienced.
• Be careful when using tools around water and electrical connections.
• Make sure the floor around the freezer is dry to prevent electric shock.

Tools You May Need

• Screwdrivers (Phillips and flathead)
• Pliers
• Adjustable wrench
• Thermometer
• Multimeter (for testing electrical components – advanced)
• New water filter
