Quick answer
Record the exact message and model first. KitchenAid says a fault message may clear after following the display instruction or removing power for one minute. If it returns, stop using the microwave and request service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Photograph the complete display and record the model, function, and timing without removing a cover.
Expected result: The message is readable and tied to one function, or appears at startup.
Next step: Use the exact model manual and stop if the message returns or the door is damaged.
Why this matters
Why: The message and model determine the correct instruction; an unknown code cannot identify a part.
-
Check 2
Follow only the displayed instruction while keeping the door and controls intact.
Expected result: The message clears, or returns during the attempt.
Next step: Stop testing and give service the code, model, and sequence.
Why this matters
Why: A recurring message indicates the condition remains.
-
Check 3
If the manual permits it, switch off the microwave circuit for one minute, restore power, and observe the display.
Expected result: The display stays clear, or the message reappears.
Next step: Do not repeat resets or open the unit; request service.
Stop if: Never operate with smoke, arcing, a damaged door, or a removed cover.
Why this matters
Why: The documented reset did not correct a recurring condition.
