If your Thermador refrigerator ice dispenser not working, start with the dispenser door. A damaged or stuck dispenser door is the most common reason the fridge won’t release ice, and you may need to remove the control panel or frame to inspect it. If the door looks fine, the dispenser control board and dispenser switches are the next likely causes; a faulty board can cut power to the whole dispenser system, while a bad switch will stop voltage from reaching the motor. After that check the crushed/cubed ice solenoid and the refrigerator’s main control board, and use a multimeter to test for continuity before buying parts. Don’t forget the simple fixes: an ice chute jam from clumped cubes can block dispensing, and running warm water through the chute often clears it. Whether the symptom reads ice dispenser not working, refrigerator not dispensing ice, or ice maker not dispensing ice, Repair Clinic stocks the replacement parts you need—enter your model number on RepairClinic.com to find the exact part for your refrigerator.
01 - Thermador Refrigerator Dispenser Door
The dispenser door is opened by a motor or a solenoid to dispense the ice, but if the door is broken, it may not open properly in order to release the ice. You should inspect the dispenser door for damage to determine if the component should be replaced. You may have to remove the dispenser control panel or frame to access and inspect the dispenser door.

02 - Thermador Refrigerator Dispenser Control Board
The dispenser control board governs most of the functions of the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the control board is more likely to be at fault.
The dispenser switches send voltage to the dispenser. If one of the dispenser switches is defective, the dispenser will not work. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity. If a dispenser switch does not have continuity, replace it.
The crushed/cubed ice solenoid is the component that opens and closes a door in the ice bucket auger housing to allow the fully formed ice cubes to pass through or to divert the cubes through a crushing blade system to crush the ice when that option is chosen. If you don't hear a "clunk" sound when switching between the "Crushed" and "Cubed" ice options, it's likely the crushed/cubed ice solenoid is defective. You can use a multimeter to test the solenoid for continuity, a continuous electrical path present in the component. If the solenoid has no continuity, the component is faulty and will need to be replaced.
A refrigerator's main control board governs most of the functions of the appliance including the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the main control board is more likely to be at fault.
