What you came for
Read F3 E0 this way: the reading arriving from the oven temperature sensor or the control and the wiring between them fell outside the band the control is built to trust. The machine protects itself by refusing to heat on an unverified reading, which is why the cycle ends early.
The code and what the manufacturer documents for it
Reference| Code | Documented meaning |
|---|---|
| F3 E0 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What is happening apart from the display
- Temperature drifts, or the display disagrees with the food — A probe reading a few ohms off is still inside its window, so the cabinet runs cool or hot before the code ever latches.
- The appliance runs longer than it used to for the same result — A reading that is drifting rather than failing stretches every cycle before it ever raises a code.
- NEAR MISS - nothing heats and no code shows at all — That is a power or element fault rather than a reading fault, and it belongs on the page for that symptom.
The ranked causes behind this reading
- A loose or corroded connector at the sensor — Ranked first because it is the failure that needs no part: the probe is fine, the joint carrying its signal is not, and heat cycling at the back of the cavity is what works a pin loose.
- A chafed or pinched harness between the probe and the board — Third: a wire rubbed through against sheet metal reads exactly like a failed probe from the board's side, which is why the harness is checked before the board is condemned.
The cheapest checks first
- Power the machine down fully and see whether the code returns — Costs nothing and separates a latched one-off read from a live fault.
- Follow the harness for rub marks where it crosses metal — A witness mark tells you the fault is in the wire, not in the part at either end.
The owner-side procedure
- Let the cavity reach room temperature before anything else — A hot resistance reading means nothing, and a hot cavity is the reason half of these codes cannot be diagnosed on the spot.
About 45 min
- Run the shortest cycle the appliance offers and watch for the code — A short cycle that stays clean while a long one fails tells a technician the fault is thermal.
About 20 min
- STOP HERE if the next step is a meter across the probe terminals — That means a panel off and a connector back-probed, which is where an owner check ends and a service call begins.
What to do before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Leave every switch and interlock wired as the manufacturer fitted it: they are what stops the appliance running in a state it should not.
When this is a service call
Call once the code survives a full power-down: a repeatable reading fault is a probe, a harness or a board, and telling those three apart needs a meter and the resistance table for that model line. One exception to the order above, because it is about safety rather than cost: call straight away if you smell hot insulation or see discoloured wiring at the back — a connector hot enough to discolour is arcing, and that is a different and more urgent problem than the reading the code named.

What this page does not cover
Written for the model lines that use this probe on this cavity, this page describes what the code means and how to work through it, nothing more specific. A family-level or model-level page, where one exists, is the better answer for your unit - the index below lists what is available.
