Plain language
What this code means
Per the KitchenAid use & care manual Error Handling section, RTD ERROR indicates the RTD is open or shorted. The manual directs you to contact a KitchenAid dealer or authorized service agency rather than attempt internal repair.
Signs
Symptoms you may notice
Preheat, temperature regulation, or baking results may be abnormal.
The oven may stop heating or refuse a cooking mode while the sensor reading is invalid.
The code/message can return as soon as the control checks the RTD circuit.
Why it happens
Possible causes
An RTD sensor circuit that is open, shorted, or outside expected range.
Harness or connector damage between the RTD and control.
A control input problem after the sensor circuit has been verified.

Contact a KitchenAid dealer or authorized service agency as the manual directs
Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you ever smell gas, stop immediately, do not operate any switches, leave the area and contact your gas provider and a qualified technician. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
Please avoid
What not to attempt
Do not open internal panels or access high-voltage components
Do not bypass door locks, safety switches or interlocks
Do not adjust, disconnect or repair any gas connection or valve

You can correct an obvious external condition and use the normal owner-approved restart or acknowledgement procedure. If the same code returns, clearing the display again does not repair the cause.
Only if the condition is clearly a normal status/maintenance indication and the appliance is operating normally. Stop using it for smoke, burning odor, arcing, repeated breaker trips, uncontrolled heating, gas odor, active leakage near electrical parts, or a significant loss of refrigeration.
No. The code identifies a condition or diagnostic path. Model-specific testing should confirm the failed component before parts are ordered.
