What Letter followed by a number means on a KitchenAid range

KitchenAid ranges display alphanumeric fault codes, formatted as a letter followed by a number, to indicate that the control system has detected a malfunction in one or more subsystems. These codes are generated by the electronic control board, which continuously monitors components such as the oven temperature sensor, door latch mechanism, keypad, and heating elements. When a value falls outside of expected parameters, the board logs the condition and surfaces it as a visible code on the display panel.

The specific letter and number combination identifies which subsystem triggered the fault. For example, codes referencing temperature sensing typically point to an open or shorted oven sensor circuit, while codes related to the door lock assembly indicate the latch motor or switch did not complete its expected cycle. Because this data entry covers the general format rather than one specific code, the root cause can vary significantly depending on which code is actually displayed on the unit.

As a first step, pressing the OFF or CANCEL button clears the display and resets the control board's active fault state. If the code does not return after normal use, the fault may have been a transient electrical event such as a voltage spike or brief sensor dropout. If the code reappears, the fault is persistent and requires hands-on diagnosis of the specific component or circuit indicated by the letter-number combination displayed.

Common causes of Letter followed by a number

  1. 01

    Oven temperature sensor fault

    Part replacement

    A failed or out-of-range oven temperature sensor is one of the most frequent triggers for alphanumeric fault codes on KitchenAid ranges. The sensor may have an open or shorted circuit, which the control board detects during operation or self-test.

  2. 02

    Electronic control board error

    Wiring / connection

    The main control board can generate a fault code due to an internal processing error, a firmware issue, or physical damage from heat or moisture. A one-time code that clears and does not return often points to a transient board-level event.

  3. 03

    Door latch or lock mechanism failure

    Part replacement

    On self-cleaning models, a fault code can appear when the door latch motor or its associated switch does not complete its travel within the expected time window. Inspect the latch assembly for obstructions or wear.

  4. 04

    Keypad or control panel malfunction

    Part replacement

    A stuck, shorted, or unresponsive key on the touchpad can cause the control board to register a fault. If specific buttons feel unresponsive or the display behaves erratically, the keypad membrane may need replacement.

  5. 05

    Loose or damaged wiring connection

    Wiring / connection

    Vibration and heat cycling can loosen wiring harness connectors between the control board and sensors or actuators. A fault code that appears intermittently often indicates a connection that is marginal rather than fully failed.

Frequently asked questions about Letter followed by a number

What does Letter followed by a number mean on a KitchenAid range?
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.
Can I fix this error code myself without calling a technician?
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.
Is it safe to keep using my KitchenAid range when an error code is showing?
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.
Will resetting the range clear the error code permanently?
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.
How much does it cost to repair a KitchenAid range fault code?
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.
