GE Range Error Code E015

ESEC self test failed

GE codesGE range codes

ESEC self test failed — may indicate the ESEC-UIB is not receiving a synchronization signal from the ESEC-Relay Board.

First step from the service manual

Check if J2 pin 5 on the ESEC-Relay Board is wired to P4 pin 5 on the ESEC-UIB. If wiring is good and the problem persists, replace the ESEC-UIB. If the problem still persists, replace the ESEC-Relay Board.

What E015 means on a GE range

Error code E015 on a GE range indicates a failure during the ESEC (Electronic Surface Element Control) self-test routine. Specifically, this error points to a communication breakdown between two key control components: the ESEC-UIB (User Interface Board) and the ESEC-Relay Board. During normal startup and operation, the ESEC-Relay Board transmits a synchronization signal to the ESEC-UIB. When that signal is absent or cannot be detected, the self-test fails and E015 is logged.

The synchronization signal travels from J2 pin 5 on the ESEC-Relay Board to P4 pin 5 on the ESEC-UIB. This specific wiring path is the first point of failure to investigate. A loose connector, damaged wire, or corroded pin at either terminal can interrupt the signal entirely, causing the self-test to fail even though both boards may be functioning correctly on their own.

If the wiring between J2 pin 5 and P4 pin 5 is confirmed to be intact and properly seated, the fault lies within one of the two boards. The diagnostic sequence calls for replacing the ESEC-UIB first, since it is the board performing the self-test and detecting the missing signal. If the error persists after replacing the UIB, the ESEC-Relay Board is the next component to replace, as it would then be confirmed as the source of the missing synchronization output.

Common causes of E015

  1. 01

    Loose or disconnected wiring between boards

    Wiring / connection

    The wire connecting J2 pin 5 on the ESEC-Relay Board to P4 pin 5 on the ESEC-UIB may be loose, unplugged, or improperly seated. Inspecting and reseating both connectors is the first step before replacing any parts.

  2. 02

    Damaged or broken signal wire

    Part replacement

    Physical damage to the wire running between the two boards can interrupt the synchronization signal. Check the wire along its entire length for cuts, pinching, or burn marks that could cause an open circuit.

  3. 03

    Corroded or faulty connector pins

    Wiring / connection

    Corrosion or bent pins at J2 pin 5 or P4 pin 5 can prevent a reliable electrical connection even when the connector appears seated. Inspect both pin locations closely for oxidation or physical deformation.

  4. 04

    Failed ESEC-UIB

    Part replacement

    If the wiring is confirmed good, the ESEC-UIB itself may have an internal failure preventing it from receiving or registering the synchronization signal. Replacing the ESEC-UIB is the next step in the diagnostic sequence.

  5. 05

    Failed ESEC-Relay Board

    Part replacement

    If replacing the ESEC-UIB does not resolve the error, the ESEC-Relay Board is likely not generating the synchronization signal at all. Replacing this board is the final step in the diagnostic process.

Frequently asked questions about E015

What does E015 mean on a GE range?
E015 indicates that the ESEC self-test has failed because the ESEC-UIB is not receiving a synchronization signal from the ESEC-Relay Board. This is a communication fault between two internal control boards that manage the surface elements. The issue can stem from a wiring problem between the boards or a failure in one of the boards themselves.
Can I fix E015 on my GE range myself?
A knowledgeable DIYer can check the wiring connection between J2 pin 5 on the ESEC-Relay Board and P4 pin 5 on the ESEC-UIB, since a loose or disconnected wire is the most common cause. However, if the wiring is intact, resolving the error requires replacing circuit boards, which involves working inside the range's control system and is generally better suited to a qualified appliance technician.
Is it safe to use my GE range when E015 is displayed?
E015 indicates a failure in the electronic control system that manages the surface elements, so it is not recommended to use the range while this error is active. The self-test failure means the control system cannot confirm normal operation, which could lead to unpredictable behavior from the surface element controls. Discontinue use until the fault is diagnosed and repaired.
Will resetting my GE range clear the E015 error?
Resetting the range by cycling the power may temporarily clear the display, but the error will return if the underlying cause has not been addressed. Because E015 is triggered by a self-test that runs during startup, the fault will be detected again each time the range powers on. A proper repair of the wiring or the affected board is needed for a lasting resolution.
How much does it cost to repair a GE range with error code E015?
Repair costs vary depending on what needs to be replaced. If only a wiring repair is needed, costs are typically lower, generally in the range of $75 to $150 for a service call and labor. If the ESEC-UIB or ESEC-Relay Board requires replacement, parts and labor combined can range from $200 to $500 or more depending on part availability and local labor rates.
