--- title: "JennAir E24: the cavity hit its 500-degree limit" description: "What E24 means on JennAir E24: the cavity hit its 500-degree limits, what to check before booking, and when it is not a failure at all." url: "https://microwaverepair.center/error-codes/jennair-e24/" --- # JennAir E24: the cavity hit its 500-degree limit A JennAir convection hood combination shuts down if the cavity temperature climbs to roughly 500°F. ## 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. JennAir microwave display What to do when E24 shows on the microwave ### Kind of code Sensors 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 to Microwave 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 as What 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. ### Make JennAir JennAir microwaves looked at in place, with the breaker, the door switches and a one-minute heat test covered before any part is priced. ### Source JennAir Product Help, over-the-range microwave: E24 From JennAir's help pages for its microwave hood combinations (Euro-style, including the convection models). The code set varies with the control generation, so a code missing from your model's manual may not apply to it. E24 applies only to models with convection. ## 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. 01 Keep the door shut and let the unit cool on its own. 02 Turn the microwave off at the circuit breaker, count a full minute, then restore power. 03 If there is any smoke or flame inside, leave the door closed and the breaker off; do not restart it. 04 Book a visit if E24 appears on the next convection use. ### Still there? It usually turns into [microwave control board and touchpad repair](https://microwaverepair.center/services/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. ## What you may notice with it. The microwave problems E24 tends to arrive with. Answer these at the microwave before anyone is booked.

Keep the door shut and let the unit cool on its own. If it comes back, it needs a visit. ### What is the first thing to do when a JennAir shows E24? Leave the door closed, cut the breaker and let it cool. A closed door starves any flame inside. ### Does E24 on JennAir always mean it really overheated? No. JennAir names the thermal sensor, the gas sensor and the board as possible causes, so false readings happen. ### Should I use my JennAir again after E24 clears? Have it checked first. An overheat stop on a unit mounted under cabinets is worth a technician's look. --- **[Read on the site: JennAir E24: the cavity hit its 500-degree limit](https://microwaverepair.center/error-codes/jennair-e24/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
