KitchenAid Range Error Code Letter followed by a number

An alphanumeric code displayed as a letter followed by a number indicates that the electronic control board has detected a fault in a specific subsystem of the range. The letter generally identifies the category of the fault, such as a sensor, door, or control circuit, while the number narrows it down further. Pressing OFF will clear the display, but if the code returns, the fault is still present and requires service.

It depends on which system the code is referencing. A fault related to temperature sensing could mean the oven is not regulating heat correctly, which is a safety concern if the unit continues to operate. It is best to stop using the range and clear the code first. If the code returns, avoid operating the appliance until the fault is diagnosed and repaired.

Repair costs depend on which component is causing the fault. A replacement oven temperature sensor typically falls in the range of $20 to $60 for the part, while a new control board can range from $150 to $350 or more. Adding a technician's labor for diagnosis and installation generally brings the total service cost to somewhere between $100 and $500, depending on the specific fault and local labor rates.

The first step is always to press the OFF or CANCEL button to reset the control board and clear the display. If the code does not come back, the issue may have been a one-time electrical event. If it reappears, diagnosing the specific cause requires identifying the exact code displayed and testing the related component, which may be within reach of a knowledgeable DIYer but often calls for a qualified technician.

Pressing OFF resets the active fault display and may clear a code caused by a transient event such as a power fluctuation. However, if the underlying component or circuit is genuinely faulty, the code will reappear during the next use cycle. A reset is a useful first diagnostic step, but it is not a repair for a persistent fault.
