Straight to it
1d22 is a report, not a diagnosis: it says 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.

What an owner observes
- 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.
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.
- Oven temperature sensor out of tolerance — Second: the element itself drifts or opens with age, and once it reads outside the accepted band the control has nothing to work from.
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.
What you can do without tools
- 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.
Where the risk actually is
Safety
Isolate the appliance first. Unplug it or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off.
When a reset is not the answer
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. 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.
