Symptom
The door remained open
The complaint was not simply a misaligned handle; the assist mechanism did not pull and hold the door shut.
Confirmed premium built-in case · Thermador
Free Airflow Through the Hose Was Not the Requirement
The door-assist system needed to hold vacuum. Once ordinary shelf interference was excluded, replacing the faulty closer module restored repeatable closing.
What the source establishes
- The built-in refrigerator door remained in an open position instead of pulling closed.
- The hose itself could be blown through, but the vacuum system was expected to hold rather than leak.
- Food and shelf interference were considered as simpler alternatives.
- The closer module was replaced.
- The technician cycled the door about twenty times and reported normal operation.
A similar symptom can have a different cause on another appliance or model.
How the evidence narrowed the diagnosis
Vacuum path
The system had to hold, not merely pass air
A hose that can be blown through does not demonstrate that the assembled closer is leak-free.
Verification
Repeated door cycles stayed normal
About twenty open-close attempts after module replacement provided the reported outcome.
What the evidence supports
The completed repair supports a failure within the vacuum-assist closer module. An expert considered a vacuum leak the likely mechanism, but the removed module was not tested to locate the leak.
The new module restored repeatable closing
After the module was replaced and the refrigerator restarted, the door operated normally through roughly twenty repeated tests.
What should be verified next
First remove food or shelf interference and document the exact door gap. If the assist still fails, a technician can test whether the vacuum assembly holds and identify the correct model-specific module.
