The reading in two sentences
The short reading of 1d22 on a KitchenAid oven: there may be a problem with the oven temperature sensor, the control, or the wiring associated with them. Do not cook anything that depends on the temperature being right: the control has flagged the circuit it measures the cavity with. Most of what follows is diagnosis rather than repair, and the repair end of it is a technician job.
Error codes
Reference| Code | Meaning |
|---|---|
| 1d22 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What else is happening when this shows
- Baking results have drifted, or the oven shuts down early — The control acts on what the sensor reports, so a wrong reading shows in the food first.
- The code appears as soon as heating starts — An open or shorted sensor is caught the moment the control starts watching it.
- NEAR MISS — nothing heats at all and there is no code — That is a heating circuit or supply fault, not a sensor fault, and it is a different page.
What triggers 1d22, most likely first
- A drifted or open sensor probe — It goes first because the reading names it first and because the probe lives in the hottest part of the oven, heated and cooled at every use until it drifts out of the accepted range.
- A degraded connector or lead on the sensor circuit — The plug sits behind the cavity where it gets hot, and a connection that has failed there reads exactly like a dead probe while costing far less to put right.
- A control board that misreads the sensor circuit — Last: the board is the expensive candidate, and the four cheaper ones above have to be eliminated before it can be blamed honestly.
The order to work through
- Compare the oven against a separate oven thermometer at one setting — The size and direction of the error is worth knowing before the visit.
- Ask whether the reading is wrong or absent — A wrong reading points at drift or position; an absent reading points at an open circuit.
- Check whether the code appears cold or only once hot — Cold means the circuit is already out; hot-only means the sensor is failing at temperature.
- Body: Take the temperature out of the picture before the parts: cold, heating and hot each produce a different version of this fault.
The reset and the checks that follow it
- Heat the oven to one setting with a thermometer inside, note the difference, then let it cool and repeat once — Two readings at the same setting distinguish a steady offset from an unstable circuit.

- Run the appliance and note when the code lands — Cold, during heat-up, or at temperature. That single observation shortens the diagnosis considerably.
About 45 min
- Let the appliance cool fully and try once more — A sensor that only fails hot behaves differently from one that is simply open, and this is how you tell.
About 60 min
- STOP HERE — the sensor and its plug sit behind a panel — Reaching either means opening the appliance next to live terminals, which is service work.
Before a panel comes off
Safety
Isolate the oven at its breaker before removing a panel and treat the terminals as live until you have. Let the cavity and the glass cool fully first. On a gas model, never switch anything on or off if you smell gas: leave and call the gas utility from outside.
Where an owner check ends
Call once the code survives a power cycle, or as soon as the results are wrong enough to matter.

What is deliberately not here
Treat this as the general KitchenAid oven reading. It stops short of anything model-specific — part numbers, harness colours, connector layouts and service-mode entry — because those differ by family and a technician takes them from the rating plate rather than from a code. A family- or model-specific page, where one exists, is linked from the code index below and is the closer answer.
