What else belongs to the microwaves
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About GE microwave error code 18
What 18 means, in the maker's own words
Not an error. GE documents 18 in the display as the Power Watch code, which some models show to report the power level rather than a problem.
Where this code actually appears
On the control panel, and usually with a sound. GE describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.
What to do about it
- Nothing needs fixing.
- If the display is showing it constantly and the appliance will not cook, that is a different problem and worth a call.
Where this goes next
The job this usually becomes is microwave repair, and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 306-2503 and describe what the display is doing before booking anything.
