F1E6 points to the microwave thermistor or sensor circuit on a JennAir wall oven; the owner step is a breaker reset.
Model compatibility: JennAir reuses codes across series and model years, so F1E6 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
A possible problem with the Microwave Thermistor or Sensor, or the associated wiring.
JennAir carries F1E6 on two pages, the built-in microwave and the wall oven, with identical wording: a possible problem with the Microwave Thermistor or Sensor, or its wiring.
About thermistors
A thermistor is a small temperature sensor. Its electrical resistance moves up and down with temperature, so a control can read from it. This is general background; JennAir gives no location for this sensor and no temperature it watches.
The listed checks
Switch the oven’s breaker off for sixty seconds.
Switch it on.
Remain close for a minute, checking whether F1E6 comes back.
Check that the oven runs.
When it will not clear
A sensor and its wiring are named, and nothing more than the reset is offered. So a repeat of the code is a matter for service, and the sensor should not be reached by the owner.
Answers
Which of the two pages should I trust? They agree; the wording for F1E6 is the same on the wall oven and built-in microwave pages.
Is it the same as F4E1? No. F4E1 has a page of its own and pairs the thermistor with the appliance manager.

F4E2: the microwave sensor or thermistor, together with the appliance manager
F4E3: the microwave exhaust air temperature sensor
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.
