TST/Display tail missing; connection issue between UIB and glass touch panel.

First step from the service manual

Check connection between UIB (connector J2, J3 & J4) and glass touch panel. If connections are good, replace UIB. If problem persists, replace touch panel.

What E14 means on a Electrolux range

The E14 error code on an Electrolux range indicates a missing or failed communication signal between the User Interface Board (UIB) and the glass touch panel. Specifically, this code points to a broken or absent TST/Display tail connection, which is the flexible ribbon or cable assembly that carries control and display signals between these two components. The UIB communicates with the glass touch panel through connectors J2, J3, and J4, and if any of these connections are absent, loose, or damaged, the control system detects the loss of signal and triggers the E14 fault.

The most common cause is a loose or disconnected ribbon cable at one or more of the three UIB connector points. These connectors can work loose over time due to vibration, thermal cycling from normal cooking use, or physical disturbance during cleaning or servicing. A physically damaged cable, such as one that is torn, kinked, or has corroded contact points, can also produce this error even when the cable appears to be fully seated.

If the physical connections at J2, J3, and J4 are confirmed secure and the error persists, the fault is typically located in the UIB itself or the glass touch panel. A failed UIB may be unable to detect or process the signal from the touch panel, while a faulty touch panel may fail to transmit the required signal back to the UIB. Diagnostic protocol calls for replacing the UIB first, then the touch panel if the error continues after board replacement.

Common causes of E14

  1. 01

    Loose or disconnected cable at UIB connectors

    Wiring / connection

    The ribbon cable connecting the glass touch panel to the UIB may have come loose from connectors J2, J3, or J4. Inspecting and firmly reseating each connector is the first step and often resolves the error without replacing any parts.

  2. 02

    Damaged ribbon cable

    Part replacement

    The flexible tail or ribbon cable linking the UIB to the glass touch panel may be physically damaged, kinked, torn, or have corroded contacts. Even if seated, a damaged cable cannot carry the required signal and will need to be replaced.

  3. 03

    Failed User Interface Board (UIB)

    Part replacement

    If the connections at J2, J3, and J4 are all secure and intact, the UIB itself may have failed internally and can no longer detect or process the touch panel signal. Replacing the UIB is the next recommended diagnostic step.

  4. 04

    Faulty glass touch panel

    Part replacement

    If replacing the UIB does not clear the error, the glass touch panel itself may be defective and failing to transmit the required signal. The touch panel would need to be replaced to restore normal operation.

Frequently asked questions about E14

What does E14 mean on a Electrolux range?
E14 indicates a missing or interrupted connection between the User Interface Board and the glass touch panel on your Electrolux range. The control system has detected that the TST/Display tail signal is absent, which prevents normal communication between those two components. This can result from a loose cable at UIB connectors J2, J3, or J4, a damaged ribbon cable, or a failed board or touch panel.
Can I fix the E14 error myself?
A homeowner or technician comfortable working inside appliance control panels can attempt to fix E14 by checking and reseating the cable connections at the UIB connectors. If the connections look secure and undamaged, the repair will require replacing the UIB or the glass touch panel, which involves sourcing the correct parts and disassembling the control panel area. If you are not comfortable working with electronic components, a professional technician is recommended.
Is it safe to use my Electrolux range while the E14 code is showing?
An E14 error affects the touch control interface, meaning the touch panel may not respond reliably or at all. Operating the range in this condition is not recommended because you may not be able to accurately set or monitor cooking functions. It is best to resolve the error before continued use.
Will resetting my Electrolux range clear the E14 error?
Resetting the range by disconnecting power for a few minutes may temporarily clear the E14 code, but if the underlying connection problem or component failure is still present, the error will return. A lasting fix requires inspecting the cable connections at the UIB and replacing the UIB or glass touch panel if the connections are found to be secure.
How much does it cost to repair an E14 error on an Electrolux range?
If the fix is simply reseating a loose cable, there is no parts cost involved and a technician visit would only incur a service call fee, typically in the range of $75 to $150 depending on your location. If the UIB needs to be replaced, parts and labor can range from $150 to $350 or more. Replacing the glass touch panel may carry a similar or higher cost depending on the specific model.
