Questions people ask about 00
What does 00 mean on a Thermador range?
Code 00 on a Thermador range is a no-fault status indicator. It means the control board completed its diagnostic routine and found no errors, failed sensors, or communication faults. This code requires no repair action and is simply a system confirmation of normal status.
Is it safe to use my Thermador range when it shows code 00?
Yes, code 00 indicates no fault conditions are present, meaning the control system has not detected any safety-related issues. The range is considered safe to operate normally when this code is displayed.
How much does it cost to repair a Thermador range showing code 00?
Because code 00 indicates no fault is present, there is typically no repair cost associated with it. If a technician visit was required to diagnose the unit and code 00 was the result, you may see a standard diagnostic service fee ranging from around $75 to $150 depending on the service provider and region.
Do I need to fix anything when code 00 appears on my Thermador range?
No action is required when code 00 appears. It is not an error in the traditional sense but rather a confirmation that no faults are detected. If your range has been displaying symptoms alongside code 00, the issue may be intermittent and worth monitoring during actual operation.
Will resetting my Thermador range clear code 00?
Code 00 does not need to be cleared because it is not a fault code. Performing a reset simply restarts the control board, which will again return code 00 if no faults are found during the subsequent diagnostic cycle. Resetting is unnecessary in this situation.
