What F1E2 means on a KitchenAid range

The F1E2 error code on a KitchenAid range indicates an internal board failure specifically related to an analog-to-digital (A/D) conversion error within the Low-voltage Control Circuit (LCC) 180/190 control board. The A/D converter is a critical component on the control board that translates analog signals, such as sensor voltage readings from temperature probes and other inputs, into digital data the board's processor can interpret. When this conversion process fails or produces readings outside acceptable parameters, the board flags an F1E2 fault and halts normal operation to prevent unsafe or inaccurate control of the appliance.

This type of failure is almost always rooted in the control board itself rather than in any external wiring or connected component. The A/D error can result from a failed or degraded integrated circuit on the board, corrupted firmware, power fluctuations that have stressed board components, or general electronic component failure over time. Because the fault originates internally within the LCC board's circuitry, external resets rarely resolve it permanently.

Diagnosing this code begins by entering the range's Diagnostics Mode using the sequence CANCEL, CANCEL, START. If the F1E2 code is confirmed in diagnostics, the control board is the identified failed component. The appropriate repair at that point is to disconnect power to the range and replace the LCC 180/190 control board. No further component-level testing of sensors or wiring is required once the fault is confirmed through the diagnostics sequence.

Common causes of F1E2

  1. 01

    Failed LCC control board (A/D circuit)

    Part replacement

    The analog-to-digital converter circuit on the LCC 180/190 control board has failed internally. This is the primary cause of F1E2 and is confirmed when the code reappears after entering the diagnostics sequence.

  2. 02

    Power surge or voltage spike damage

    Part replacement

    A power surge or unstable supply voltage can degrade or destroy the A/D converter and related components on the control board. If the error appeared after a power event, the board's internal circuitry is likely compromised.

  3. 03

    Corrupted or failed board firmware

    Part replacement

    In some cases, the board's onboard firmware can become corrupted, causing the processor to misread or fail the A/D conversion process. This presents identically to a hardware failure and still requires board replacement.

  4. 04

    Long-term component degradation

    Part replacement

    Electrolytic capacitors and other small components on the control board degrade over years of heat exposure inside the range. This gradual failure can eventually cause the A/D circuit to produce out-of-range readings and trigger F1E2.

Frequently asked questions about F1E2

What does F1E2 mean on a KitchenAid range?
F1E2 indicates an internal analog-to-digital (A/D) conversion error on the LCC 180/190 control board. The control board has detected a failure within its own circuitry and is no longer able to process signals correctly. This is a board-level hardware fault, not an external sensor or wiring issue. The control board must be replaced to clear the fault and restore operation.
Can I fix the F1E2 error myself without calling a technician?
You can confirm the fault yourself by pressing CANCEL, CANCEL, START to enter Diagnostics Mode and verifying the F1E2 code is displayed. If confirmed, the repair requires disconnecting power to the range and replacing the LCC 180/190 control board. This is a moderately complex repair that involves working with the range's electrical system, so comfort with appliance disassembly and basic electrical safety is important before attempting it.
Is it safe to use my KitchenAid range while it is showing F1E2?
It is not advisable to continue using the range while the F1E2 code is active. The control board's inability to accurately process analog signals means the range cannot reliably regulate temperature or respond correctly to control inputs. This could lead to unpredictable heating behavior, making continued use a potential safety risk.
How much does it cost to repair a KitchenAid range with an F1E2 error?
The cost depends on whether you repair it yourself or hire a technician. A replacement LCC control board for this range typically runs in the range of $150 to $350 for the part alone. If you use a professional appliance repair service, total costs including labor generally fall between $250 and $500 or more depending on your area and the service provider.
Will resetting my KitchenAid range clear the F1E2 error code?
A basic power reset by unplugging the range or cycling the breaker is unlikely to permanently clear the F1E2 error because the fault is caused by an internal hardware failure on the control board. The code may temporarily disappear after a reset but will return once the board's A/D circuit fails again. Permanent resolution requires replacing the control board.
