What E23
actually means.
KitchenAid convection hood combinations preheat with an element and fan inside the cavity wall. E23 means half an hour passed without the target temperature being reached, which points to the heater, the board that drives it or the wiring between them.

What to do when E23 shows on the microwaveKind of codeHeating and magnetron
The microwave ran a cycle and the control saw no heat come of it, or saw the power section behave strangely. The cause sits somewhere in the chain that makes the energy: the magnetron, the high-voltage diode and capacitor, the transformer that feeds them. All of it lives behind the outer cabinet, where a capacitor keeps a dangerous charge even unplugged, so after a restart the owner's part ends at booking the visit.
Usually leads toMicrowave magnetron repair
Replacing the tube that makes a microwave's heat, after proving the parts that feed it are sound, and renewing the waveguide cover and any pitted metal where sparks have been.
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.

SourceKitchenAid Product Help, over-the-range microwave: E23
Listed on KitchenAid's help pages for over-the-range microwaves; the lettered F-codes belong to the newer hood controls, and the exact code set depends on the model generation. E23 applies only to models with convection.
Before you book,
in this order.
Each step comes from KitchenAid's own guidance for E23 on its microwaves. Follow it to the end: the last card says whether this is a visit.
Switch the microwave off at the breaker for one full minute, then switch it back on.
Leave it idle for a minute and watch the display; if the code does not return, run a short test cycle.
Try a plain microwave cycle with a cup of water; microwave heating uses different parts and may still work.
If convection preheat fails again, book a visit to test the convection element.

It usually turns into microwave magnetron repair. Book with the code and the model number.
What not to do
E23 does not mean the magnetron has failed; microwave-only cooking uses separate parts. It is also not caused by opening the door once during preheat.

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.
Countertop microwave
A microwave that stands on the counter or a shelf and plugs into an outlet beside it, from a compact model for a dorm to a large inverter or convection unit in a busy family kitchen.
In KitchenAid's own words
The oven did not reach Pre-Heat Temperature within 30 (thirty) minutes.

Three details make the booking useful: the characters or beeps just as they appeared, every character of the model number, and whether a cup of water still warms up. With those, the technician arrives already halfway to the answer.
