Error codeF8E3
ApplianceWall Oven
Quick answer
F8E3 on a JennAir wall oven refers to the Oven Cooling Fan or wiring; a commercial-style range gets a reset and no cause.
Model compatibility: JennAir reuses codes across series and model years, so F8E3 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
Wall ovens: possible Oven Cooling Fan or wiring problem. Commercial-style ranges: a reset with no cause.
Read what JennAir actually writes for F8E3: it is brief, and the two articles disagree about whether a part is named.

Wall oven wording
JennAir says the Oven Cooling Fan or its wiring may be at fault. Its listed response: breaker off for a minute, breaker on, then a further minute of watching the oven for any sign of F8E3.
Commercial-style range wording
The approach is a control reset. Leave the range with no power for 5 minutes, either by pulling the plug or by turning off its breaker, and then reconnect it.
After the reset
No further steps are given in either article. If the code holds, a qualified technician has to examine the appliance. Taking apart an oven connected to mains power is not a do-it-yourself job.
Next to this one
F8E2 repeats the Oven Cooling Fan wording, in its range entry and its wall oven entry alike.
F8E4 / F8E5: these turn to the Exhaust Fan Air Temperature Sensor.
