In brief
F3 E3 means the control cannot get a believable temperature reading from the oven temperature sensor: the sensor or the wiring between them is suspect. Treat the oven as out of service, because an oven regulating on a bad reading can run far too hot or too cool.
Error codes
Reference| Code | Meaning |
|---|---|
| F3 E3 | There may be a problem with the Oven Temperature Sensor, or the associated wiring. |
Signs that come with the code
- The code first appeared after a self-clean — The oven worked before the clean cycle and has raised the code since.
- An element runs without cycling off — A control that reads the cavity as cold keeps heating; if you see this, switch off at the breaker.
- NEAR MISS: the cavity never warms at all — No heat and no sensor code points at the heating element or its supply, a different fault.
Likely causes, ranked
- Sensor wiring damaged by heat or pinching — Ranked first when F3 E3 first appeared after a self-clean: the clean cycle runs the cavity far hotter than baking, and the sensor's wiring and connector take the brunt of it.
- A failed or drifting oven temperature sensor — A sensor that reads wrong, or not at all, is the most direct way to produce this code, and it is a part that wears.
- The sensor connector behind the oven — The sensor plugs into the harness at the back wall; a connector pulled half off, corroded or heat-darkened breaks the reading.
Check in this order
- Check what came before — A code that started after a self-clean or after the range was moved points at heat or pinch damage to the sensor wiring.
- Look at the probe in the cavity — With the oven cool, find the probe near the top rear of the cavity and check it stands clear of the wall and is not bent or loose.
- Reset and note the timing — Power-cycle at the breaker, preheat once, and note whether the code returns at once or only when hot.
What an owner can safely do
- Reset the control — Switch the oven off at the breaker for a few minutes, then back on.
About 5 min
- Record when it happens — Note whether the code appears at preheat, mid-bake or after a clean; it decides the order of a technician's tests.
Tools: notebook or phoneAbout 2 min
- Stop here if the next check needs a meter — Testing a part or its wiring means live terminals or disassembly, which is technician work.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. An oven that keeps heating with a sensor code can overheat; if that happens, switch it off at the breaker rather than at the panel.
When to call a technician
Call for service if F3 E3 returns after a reset, or at once if the oven keeps heating with the code showing or runs far hotter than its setting. Measuring the sensor and its harness against the model's specification is the test that decides the repair, and it needs a meter and the oven's rear connections.

What this reading does not cover
Scope: the documented meaning of F3 E3 for Jenn-Air ovens whose code list carries F3 E3 as a temperature-sensor fault. Out of scope: meat-probe codes, microwave and cooktop sensor codes, and models that read F3 E3 differently; so is model-level detail such as connector positions and part numbers. A model-specific page, where one exists, is the more precise source. A second Jenn-Air listing spaces this code differently and words it differently; confirm which one fits your model.
