What F3
actually means.
On the ZEB1227, the control stops and shows F3 when a key has been active for more than 60 seconds. Monogram names liquid on the control panel as a common cause. The ZWL1126 drawer reports the same condition as KEYPAD SHORTED – SERVICE MAY BE NEEDED.

What to do when F3 shows on the microwaveKind of codeControl board and touchpad
The electronics that read the keys and run the cycle have flagged a problem with themselves: a key that the control sees as held down for too long, a membrane keypad worn through or swollen by steam, a lost link between the keypad and the board, or a board that failed its own check after a surge. A breaker reset now and then clears a glitch; a stuck key or a code that comes straight back points to the keypad or the board.
Usually leads toMicrowave control board and touchpad repair
Tracing a dead display, keys that do not answer or a code that keeps returning to the keypad, the ribbon, the relays or the main board, and replacing only the part that failed.
Shows up asWhat a Microwave Error Code Is Telling You
A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared.

What not to do
F3 has nothing to do with the magnetron or the steam system. A repeat F3 on a dry panel is the touch control, not the main board, in most cases.

Microwave hood combination
The microwave that hangs from the wall cabinets above the burners, heating food in its cavity while its own fan, light and filters handle the steam and grease rising from the pans beneath it.
Built-in microwave
A microwave set into a tall cabinet or a wall of cabinetry at eye level, either a countertop body wrapped in a trim kit or a true built-in model, including speed and convection microwaves that brown as well as heat.
Microwave drawer
A microwave built under a counter or into a kitchen island that opens like a drawer at the touch of a key, with a motor and gears sliding its cavity out toward you.
