F3E3 on a built-in JennAir microwave is tied to the meat probe, its socket or the wiring behind it.
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
Possible problem with the oven meat probe, the meat probe receptacle, or the associated wiring.
When a JennAir built-in microwave displays F3E3, the owner manual material is talking about the meat probe system. The suspects are the oven meat probe, the meat probe receptacle and the associated wiring.
Three places the fault could be
The probe: a temperature sensor on the end of a cable.
The receptacle: the socket the probe plugs into, which lets the control read the food temperature.
The wiring that runs behind that socket.
Those three make up the entire chain, and F3E3 gives no hint about which link has the problem.
The only step JennAir lists
Switch the circuit breaker(s) off for one minute.
Switch them back on.
Monitor the unit for one minute and see whether the code returns.
Check that the oven operates.
Nothing in the built-in microwave article asks you to reseat the probe or replace it for this code, so none of that is suggested here.
If your appliance is not a built-in microwave
The wall oven article words F3E3 differently: an oven temperature sensor, the control, or wiring, with no probe mentioned. The description above comes from the built-in microwave article. A wall oven or range owner should go by the wall oven wording and say so when calling.

The 3D31 group covers meat probe codes where the advice is to verify the probe is fully seated.
