What you came for
Oven code 1d12 is the control reporting that the oven temperature sensor or the control and the wiring between them stopped answering with a value the control treats as plausible. 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 |
|---|---|
| 1d12 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
The behaviour that comes with this code
- The code appears and the cycle stops heating — Everything else looks normal — lights, fan, display — and only the heat is missing.
- The fault comes and goes with temperature — An intermittent connection opens as the metal expands and closes again when it cools, which is why the code often arrives part-way through a long cycle.
- 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 produces this code, likeliest 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.
What to check first, second and third
- 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.
Read this before touching anything
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.
The point at which you call
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.
