What the KEY OK error code actually means

KEY OK is not a problem. It is a message your Wolf microwave displays during a test to confirm that every button on the control panel is working correctly. If you see this message, it simply means the keypad passed its self-check successfully.

Questions people ask about KEY OK

What does KEY OK mean on a Wolf microwave?
KEY OK is a confirmation status message displayed during the touch control panel assembly diagnostic test on Wolf microwaves. It indicates that all keys on the control panel have been tested and are responding correctly. This is a pass result, not a fault code, and no repair is needed when this message appears.
Is it safe to use my Wolf microwave after seeing the KEY OK message?
Yes, it is safe to continue using the microwave. KEY OK is a positive confirmation that the control panel passed its self-test. It does not indicate any fault, safety issue, or component failure.
What does it cost to repair a Wolf microwave that is showing KEY OK?
No repair cost is associated with the KEY OK message because it indicates the control panel is working correctly, not that something is broken. If a technician was performing a diagnostic service call when this message appeared, you would only be responsible for the standard diagnostic or labor fee, which typically ranges from $75 to $150 depending on your location and service provider.
Do I need to fix anything when I see KEY OK on my Wolf microwave?
No action is required when KEY OK is displayed. The message confirms that the control panel is functioning correctly. Simply exit the diagnostic or test mode to return the microwave to normal operation.
Will resetting my Wolf microwave clear the KEY OK message?
Exiting the diagnostic test mode or cycling power to the unit will clear the KEY OK message from the display. Since it is a status indicator rather than a fault code, it does not need to be cleared in the same way an error code would.
