What it means, first
Read F01 this way: the resistance it reads across the oven temperature sensor or the control and the wiring between them left the window the control accepts. The control stops the heat rather than work from a reading it cannot trust, so the cycle will not finish while the code stands.
The code and what the manufacturer documents for it
Reference| Code | Documented meaning |

| F01 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you actually see and hear
- 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.
- The fault follows the weather or the time of day — A cold kitchen and a hot one put a marginal probe on opposite sides of its limit, which is why some of these arrive seasonally.
- 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.
What triggers this code, most likely first
- 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.
Check these in this order, and why
- Look at the connector at the sensor before anything is measured — Seated, clean and tight is a five-second answer to the most likely cause.
- 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-safe sequence
- 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.
Safety first, and it is not optional
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 to stop and call someone
Where an owner stops: 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. And where nobody should wait at all: 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.

The scope of this reading
This reading is written for the model lines that use this probe on this cavity, and it stays with the code in its title. If a page exists for your exact family or model, that page is the more specific answer and it should be read first; the code index linked below is where those pages are listed.
