Quick answer
Thermador identifies T36IB900SP/07 as a Freedom built-in bottom-freezer refrigerator, while the opened use-and-care guide covers the T36IB900SP model family and lists the ice-maker checks. Confirm that ice production is enabled, the freezer has reached temperature, the ice container is fully inserted, and no cubes are frozen together or blocking the ice maker. Do not pry the tray, defeat an ice-bin sensor, open the built-in cabinet or test internal wiring. If those external conditions are correct but cubes still do not release, stop treating it as a simple setting issue and use Thermador service with the full /07 model and rating-plate information.
Before you begin
Safety first
- Do not open the ice-maker housing, defeat the ice-bin detection switch, force the tray, probe internal wiring, remove the built-in unit or change water/electrical connections as a diagnostic test. Thermador/BSH recommends trained service for internal work and original parts.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Open the refrigerator settings and confirm that ice-cube production is switched on. Also check that Vacation mode is off if it was recently used; do not change service settings or enter a technician test.
Expected result: Ice production was off, Vacation mode was active, or the setting was already on with no mode conflict.
Next step: Enable ice production using the normal user menu and allow the appliance to reach its set temperature. If it was already enabled, continue with the container and temperature checks rather than repeatedly toggling it.
Why this matters
Why: The guide says ice production can be switched off from the settings menu and that Vacation mode deactivates ice production. If the setting was already correct, the symptom is not explained by a simple off state.
-
Check 2
With the freezer door open and the appliance undisturbed, confirm that the ice container is fully inserted and inspect only for cubes visibly frozen together or blocking the ice maker/dispenser. If the container is full or heavy, use both hands; use no sharp tool and do not force the tray or sensor.
Expected result: The container was not fully seated, cubes are frozen together/visible in the ice path, or the container and visible ice path are clear.
Next step: Fully seat the container or remove only loose/frozen-together cubes with a blunt plastic tool as the official guidance allows. If the path is clear and ice remains in the tray, stop before prying or dismantling the ice maker.
Why this matters
Why: Thermador says an incorrectly inserted container can stop operation and that frozen-together cubes can block the ice maker or dispenser. A clear visible path does not prove the internal ejector or heater is working.
-
Check 3
Check the freezer temperature on the user controls and whether the appliance has recently been powered on or had a large amount of ice removed. Do not lower settings beyond the manual or repeatedly cycle power to force a harvest.
Expected result: The freezer is warmer than the user setting, the appliance was recently started/emptied, or it has been operating at its set temperature long enough for normal ice production.
Next step: Allow the appliance to stabilize according to the guide and monitor one normal production period. If the freezer is at temperature and the tray still does not release ice, use the service path instead of forcing a cycle.
Why this matters
Why: Thermador states that ice production begins after the appliance reaches the set temperature, can take about 24 hours for an empty container to fill, and that a freezer that is too warm can stop ice production.
-
Check 4
Inspect only the accessible water connection for a closed supply, a kinked hose or a blocked/overdue filter. Do not remove panels or disconnect an internal line; if the connection must be altered, shut off water safely and use original parts/service.
Expected result: Water supply is absent/low, the hose is kinked, the filter is blocked/overdue, or the external water path looks normal.
Next step: Correct only an accessible supply/filter issue using the model instructions and original parts. If water conditions are normal or the tray remains stuck, contact Thermador service for an internal ice-maker diagnosis.
Why this matters
Why: Thermador lists no water supply, low water pressure, a kinked hose and a blocked filter as ice-maker causes. These conditions explain too little/deformed ice or no fill but do not by themselves prove why an already formed cube will not drop.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Ice production is off or Vacation mode is active.
Do this next
Restore the normal ice-production setting through the user menu and allow the freezer to reach temperature before judging the result.
Why this path and its safety boundary
Why it matters: The appliance may be intentionally preventing ice production rather than failing to release a cube.
-
PATH 02Next step
What you see
The container is not fully inserted or visible cubes are frozen together and blocking the ice path.
Do this next
Seat the container fully or clear only loose blockage with a blunt plastic tool and both hands; do not pry the tray or defeat the detection switch.
Why this path and its safety boundary
Why it matters: The official guide treats container seating and frozen-together cubes as user-level causes of an ice-maker stoppage.
-
PATH 03Next step
What you see
The freezer is too warm or the refrigerator was recently started or emptied of a large amount of ice.
Do this next
Let the appliance stabilize and check one normal production period. If it remains at temperature and cubes still do not release, escalate to service.
Why this path and its safety boundary
Why it matters: Ice production may be delayed by temperature recovery or the normal refill period, so a short observation is not proof of a failed ice maker.
-
PATH 04Next step
What you see
Settings, container seating, visible blockage, freezer temperature and accessible water conditions are correct, but ice remains in the tray or the ice maker has no power.
Do this next
Stop forcing the tray or running improvised tests. Contact Thermador/authorized service with the complete T36IB900SP/07 model and rating-plate information.
Why this path and its safety boundary
Why it matters: The remaining fault may be internal, and the official guide sends an ice maker without power to customer service; the symptom does not identify a specific internal part.
Helpful context
Understand the symptom
Model and variant scope
The exact Thermador support page identifies T36IB900SP/07 as a Freedom built-in fridge-freezer with freezer at bottom and exposes the model's manuals, parts and support route. The official use-and-care guide lists T36IB900SP among its covered models. This article keeps the assigned suffix /07 and uses the family guide only for user-level ice-maker behavior; it does not transfer advice from T36IB900SP/08, /06 or another product.
What “not dropping ice” can and cannot establish
A cube that remains in the tray can reflect an ice-production setting, a freezer that has not reached temperature, a full or badly seated container, frozen cubes blocking the ice maker, or a water/pressure/filter condition. Thermador's official troubleshooting list does not let the symptom alone identify an ejector motor, tray heater, valve or control-board failure.
Keep the check external
The guide permits checking the control setting, container seating, visible ice blockage, freezer temperature and water connection. It directs owners to service when the ice maker has no power and warns that improper repairs can cause electric shock; do not open the ice-maker housing or built-in cabinet to force a harvest test.
When checks do not resolve it
Need a professional?
Call Thermador or authorized service if the ice maker has no power, if ice remains in the tray after the official settings/container/temperature/water checks, or if diagnosis would require opening the ice maker, accessing wiring or moving the built-in refrigerator.
Safety scope: Do not open the ice-maker housing, defeat the ice-bin detection switch, force the tray, probe internal wiring, remove the built-in unit or change water/electrical connections as a diagnostic test. Thermador/BSH recommends trained service for internal work and original parts.
Have this ready
- Provide the complete T36IB900SP/07 model, serial/FD or rating-plate information if requested, whether ice production is enabled, freezer temperature status, container seating, visible blockage, water/filter history and whether cubes are formed but remain in the tray.
Common questions
FAQ
Does ice remaining in the tray prove the ice-maker motor is bad?
No. Thermador's official guidance also lists ice production being switched off, Vacation mode, a warm freezer, a badly inserted container, frozen-together cubes, water supply/pressure, a kinked hose and a blocked filter. The symptom alone does not identify an ejector motor or control-board failure.
Can I force the tray or bypass the ice-bin sensor to make it drop?
Do not. Thermador says the built-in ice-bin detection switch depends on correct bin insertion, and the guide warns that improper repairs can create shock or other hazards. Use only the visible container/blockage checks and then service.
How long should I wait after turning the ice maker on?
The guide says production starts after the appliance reaches its set temperature and that an empty ice container can take around 24 hours to fill. If the freezer is stable and cubes still remain in the tray, do not keep resetting it; use the service route.
