Error codeF3E3
ApplianceWall Oven
Quick answer
F3E3 has no single meaning across JennAir pages: sensor on some, meat probe on others, plus an app note.
Model compatibility: JennAir reuses codes across series and model years, so F3E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
JennAir lists F3E3 as an oven temperature sensor fault on ranges and wall ovens and a meat probe fault on commercial-style ranges and built-in microwaves.
Here the manufacturer’s own pages disagree, so “what does F3E3 mean” has no one answer.

If it is a meat probe version
For the commercial-style range, JennAir asks whether the probe is installed correctly. Put on an oven mitt or grab a potholder, and check that the probe is seated all the way in or plugged in. After that, power cycle the range: take it off its power source for five minutes, either by unplugging it or by turning off the breaker.
If it is a sensor version
These listings call for the one-minute breaker reset: breaker off, wait, breaker on, observe for a minute, then try the oven.
The mobile app message
An extra JennAir note deals with a commercial-style range that shows F3E3 in its mobile app. It says to remove power from the oven for a minute, restore it, and refresh the app. Schedule service if the code is still there.
Putting it together
Ask whether a meat probe was in use; if so, make sure it is fully seated.
Reset power for the length that suits your product.
Stop and arrange service if F3E3 returns, since the pages cannot say which cause fits your unit.
Nearby probe and sensor codes
F3E4 deals with a probe or power attachment that is not seated.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
