JennAir Wall Oven Code F3 E3: cavity sensor, or probe jack on combination units

What F3 E3 means

On JennAir JJW wall ovens, F3 E3 means there may be a problem with the Oven Temperature Sensor, the control, or the wiring. On JMW2430D-generation combination ovens the same code instead refers to the meat probe jack, reading open or shorted. You will see the code on the display, and the oven may stop heating or refuse to start a probe cycle, depending on which unit you own.

Common causes of F3 E3

Oven Temperature Sensor not reading properly (wall ovens)
Meat probe jack open or shorted (combination ovens)
Control or wiring unable to carry the sensor signal

✓ One safe check you can try

1. If you were cooking with the probe, unplug it and check the plug is clean and dry. 2. Cancel the cycle and let the oven cool. 3. Turn the breaker off for one minute and on again. 4. Start a regular bake without the probe. If F3 E3 persists, call us and tell us your model. Do not poke anything into the probe socket.

! Why to stop there

The same code points to different parts on different generations, so the model number matters.
A shorted probe jack and a bad cavity sensor need different tests.
Cleaning a jack with tools can bend the contacts and make things worse.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F3 E3F3 E3 questions

Does F3 E3 always involve the meat probe?

No. On most JJW wall ovens the notice names the cavity temperature sensor. On JMW2430D combination ovens it points to the probe jack. Your model number tells us which meaning applies.

Can I bake without the probe if F3 E3 appears?

Try it after a power reset. If the code clears, the probe or jack was the cause. If the code stays, the cavity sensor or control is involved and the oven needs service.

What information helps you most?

The full model number inside the door frame, the exact code, and whether a probe was in use. With those we bring the correct part and quote the price first.
