What E24
actually means.
A JennAir convection hood combination shuts down if the cavity temperature climbs to roughly 500°F. That can be a genuine runaway, or a false alarm from the thermal sensor, the gas sensor or the board, which is why JennAir lists all three.

What to do when E24 shows on the microwaveKind of codeSensors and temperature
The control has stopped trusting what one of its sensors reports: the cook or humidity sensor that ends a sensor reheat when steam rises, or a thermal cutout that trips when the cavity or the magnetron runs too hot. A cutout that opens stops the microwave mid-cycle and often recovers once it cools; one that keeps tripping, or a sensor program that shuts off at once every time, needs the sensor, its wiring or the airflow behind it checked.
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.

Before you book,
in this order.
Each step comes from JennAir's own guidance for E24 on its microwaves. Follow it to the end: the last card says whether this is a visit.
Keep the door shut and let the unit cool on its own.
Turn the microwave off at the circuit breaker, count a full minute, then restore power.
If there is any smoke or flame inside, leave the door closed and the breaker off; do not restart it.
Book a visit if E24 appears on the next convection use.

It usually turns into microwave control board and touchpad repair. Book with the code and the model number.
What not to do
Normal convection baking and browning stay well below the E24 limit, so this is never routine. E23, by contrast, reports too little heat, not too much.

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.
In JennAir's own words
The oven reached an overheat condition of 500F (260C).

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.
