Frigidaire Range Error Code E15

E15 on a Frigidaire range means the ESEC (Electronic Surface Element Control) self-test has failed. This self-test checks communication between the User Interface Board and the relay board, which together control the surface heating elements. The error indicates that one or both of these boards has a fault. Normal operation is interrupted until the issue is resolved.

Resetting the range by unplugging it or tripping the circuit breaker for a few minutes may temporarily clear the E15 code, but it is likely to return if the underlying board fault is still present. The ESEC self-test runs automatically and will fail again if the UIB or relay board is defective. A reset alone is not a repair.

Repair costs depend on which component has failed and whether you hire a technician. A replacement UIB typically costs in the range of $80 to $200 for the part, while a relay board may run $60 to $180. If both boards need replacement, or if professional labor is included, total repair costs can range from $150 to $450 or more depending on your location and the specific model.

Replacing the UIB or relay board involves working near high-voltage components, so comfort with appliance repair is important before attempting this yourself. The diagnostic process is straightforward: replace the UIB first, then the relay board if the error returns. Knowledgeable DIYers who are comfortable disconnecting power and swapping control boards can often handle this repair, but if you are unsure, a qualified technician is recommended.

It is not advisable to continue using the range while the E15 error is active. The fault indicates the surface element control system has failed its self-test, meaning the electronics controlling the burners may not be operating reliably. Using the range in this condition could result in unpredictable burner behavior.
