On the covered KitchenAid range, 1D11, 1D12, 1D21, 1D22 means the oven is running too hot in Bake, Broil or Clean, or the sensor reports it is First, let the oven cool completely. Then: check the sensor wiring and resistance, then look for a shorted element, then the electronic oven control.
Differential
Likely causes of “KitchenAid range code 1D11, 1D12, 1D21, 1D22”, and how to tell them apart
- 1
The oven is running too hot in Bake, Broil or Clean
What separates it The code appears with a very hot oven
How to confirm Switch off and let the oven cool fully
- 2
The temperature sensor wiring is faulty
What separates it The sensor reads wrongly
How to confirm With the range off, inspect the wiring
- 3
A relay stuck on the control
What separates it The oven keeps heating after you turn it off
How to confirm Cut power and watch the elements
- 4
A one-off after a clean cycle
What separates it The code appeared at the end of a clean
How to confirm Let it cool and reset
- 5
A control board fault
What separates it The sensor reads correctly
How to confirm The board is replaced last
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether 1D11 appeared in Bake, Broil or Clean, since the code covers all three
- How hot the oven felt and whether it kept heating after you cancelled
- Whether a self-clean or a long roast came just before the code
- The model number from the frame behind the oven door or the storage drawer

0 of 9 completedWhat to do first
ReversibleLet the oven cool completely.
Correct only the documented fault domain
ReversibleCheck the sensor wiring and resistance, then look for a shorted element, then the electronic oven control. A power reset is the whole of what KitchenAid publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Switch the oven off and cancel the cycle
ReversiblePress Cancel or Off so that no element is heating, and keep your distance from the oven door while it is very hot.
Let the oven cool fully
ReversibleWait until the oven is at room temperature, which can take hours after a clean cycle, before you test anything.
Cycle the power at the breaker
ReversibleSwitch the range off at its breaker for a minute and on again so that the control restarts.
Check the sensor wiring
ReversibleWith the range off, look at the sensor probe inside the oven and make sure that it is not bent or touching the wall.
Run a short bake and watch the temperature
ReversibleBake at a moderate setting and check with an oven thermometer whether the oven reaches the set temperature and then holds it.
Book service if 1D11 returns
ReversibleIf the code returns, a technician measures the sensor and checks the relays, and replaces the part that is at fault.
Bake with a thermometer inside
ReversibleSet the oven to 350 degrees with an oven thermometer on the middle rack. A reading far above 350 after twenty minutes means that the control is not regulating the heat, and the oven should stay off.
Model-specific
What is true of this model and not of its siblings
- The code on this page
- 1D11, an oven that is running too hot.
- Parts involved
- The temperature sensor, its wiring and the control.
- Related
- 1D12, 1D21 and 1D22 belong to the same group.
- Over-temperature means two different things
- On a KitchenAid range the 1D codes can mean that the oven really did run too hot, or that the sensor reported that it did. A sensor that reads low makes the control keep heating, and the oven then overshoots for real. A sensor that reads high makes the control think the oven is hot when it is not. The first check is therefore an oven thermometer, which tells you which kind of fault you have.
- Pro-style and true convection models
- KitchenAid's pro-style and true-convection ranges carry more sensors than a basic range, and their codes can differ between generations. Giving the technician the full model number, as well as the code, lets them bring the right sensor and avoid a second visit.
Stop boundary
When this stops being a self-service repair
- !If 1D11 returns after a full cool-down, ask KitchenAid service to bring a temperature sensor and to test the relays
- !An oven that keeps heating after it has been switched off needs its breaker off, and the range must stay unused until it is checked
- !Mention the self-clean to the technician if the code appeared during or just after one

Exact questions
Common questions
What does 1D11, 1D12, 1D21, 1D22 mean on a KitchenAid range?+
the oven is running too hot in Bake, Broil or Clean, or the sensor reports it is
Is an overheating oven dangerous?+
It needs attention, so cut power if an element stays on after the oven is switched off.
Will a reset fix it?+
Only a one-off; a returning code points to the sensor or the control.
Is the sensor the usual cause?+
Often, because a sensor that reads low makes the control keep heating.
Can I still use the cooktop?+
Yes, with care, but have the oven checked before you rely on it.
How can I tell whether the oven is really too hot?+
Place an oven thermometer on the middle rack, bake at 350 degrees and compare it with the display after twenty minutes.
Is 1D12 the same fault?+
1D11, 1D12, 1D21 and 1D22 belong to one family, and the same first steps apply to each.
