What you came for
In plain terms, F1-2 means 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.

What the appliance does alongside the code
- The code appears and the cycle stops heating — Everything else looks normal — lights, fan, display — and only the heat is missing.
- 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 likely causes in order
- 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.
Where to start, and what follows
- Power the machine down fully and see whether the code returns — Costs nothing and separates a latched one-off read from a live fault.
- Compare what the appliance claims against a separate thermometer — Ten minutes with an oven thermometer separates a drifting probe from a control that is being told the truth.
What to try before calling
- Clear the code with a full power-down — A code that does not return was a single bad read.
About 5 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.
Where an owner stops and a technician starts
The free checks above come first; past them this is a visit. 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.

What is deliberately not here
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.
