The short answer
Oven code F1-H is the control reporting that 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 observable side of this fault
- 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 probe mounted where it now reads the wrong thing — Uncommon but real: a clip that has released lets the sensing tip sit against metal or in a draught, and the reading it returns is honest about a place nobody cares about.
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.
- Only then treat the board as a candidate — Order matters because every check above is free and the board is not.
Steps you can take yourself
- 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
Safety line for this appliance: unplug it or switch off its breaker before removing any panel, and remember a capacitor can hold a charge after the power is off. Interlocks and switches stay as fitted.
When to stop and call someone
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. Short of that: 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.
