Kenmore Dryer Error Code E12

The E12 code on a Kenmore dryer signals a communication failure within the dryer's control system. The main control board has detected that it cannot properly communicate with one or more internal components. This can result from a temporary glitch, a wiring issue, or a failing control board. If the code returns after being cleared, the control board is the most likely cause.

Resetting the dryer by clearing the code is the recommended first diagnostic step and may resolve the error if it was caused by a brief communication dropout or power irregularity. However, if the underlying cause is a failing control board or damaged wiring, the E12 code will return after the reset. A persistent E12 error after resetting points to a hardware problem that requires further repair.

If the fix requires replacing the main control board, parts costs typically range from around $80 to $250 depending on the specific model, with professional labor adding another $100 to $200 if a technician is hired. If the error is caused by a loose wiring connection that can be reseated without new parts, the repair cost can be minimal. Getting the error to clear with a simple reset costs nothing and should always be tried first.

The first step is to clear the error code, exit diagnostic mode, and restart the dryer to see if the fault was a temporary glitch. If the code returns, the repair involves replacing the main control board, which is a task many experienced DIYers can handle with basic tools and the correct replacement part. If you are not comfortable working with appliance electronics, a qualified technician can perform the board replacement.

Because E12 indicates a communication failure in the control system, the dryer may not operate reliably or as intended. Running the dryer in this state is not recommended, as the control board may be unable to properly regulate the heating element, motor, or other safety-critical functions. It is best to address the fault before resuming normal use.
