What we can confirm
Code 18, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

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.
Other codes this appliance can display
an open thermal sensor from excessive cavity heat
an open humidity sensor
a shorted humidity sensor
a shorted temperature probe
a shorted touch screen
the probe is not connected
the power was interrupted
an open thermal sensor

About Monogram microwave 18 code — the Power Watch indicator
What the appliance is actually doing
The Power Watch indicator, not an error. It reports that the appliance has seen a supply problem, and it is cleared rather than repaired.
Which machines this one applies to
Monogram built-in microwaves and microwave drawers. Monogram says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.
What to do about it
- Clear it at the panel.
- If it comes back regularly, the supply to the appliance is what to look at rather than the appliance.
Where this goes next
The job this usually becomes is diagnostic visit, 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) 614-3572 and describe what the display is doing before booking anything.
