Frigidaire Range Error Code E14

E14 indicates that the control system cannot detect a valid connection between the User Interface Board (UIB) and the glass touch panel. This is referred to as a missing TST or display tail signal. The issue is almost always related to the ribbon cable or flex tail that links these two components. The range flags this code to prevent operation when the touch input system cannot communicate properly.

E14 indicates a failure in the touch panel communication circuit, which means the touch controls may not function reliably or at all. It is not advisable to use the range while this error is active, as you may not be able to properly control cooking functions or cancel operations. Power off the range until the fault is diagnosed and resolved.

If only the ribbon cable needs replacement, parts costs are generally in the range of $15 to $60 depending on the specific model. If the glass touch panel or UIB requires replacement, parts can range from $80 to $300 or more. Adding professional labor typically brings the total repair cost to between $100 and $400, depending on the parts needed and local service rates.

In many cases, yes. Start by disconnecting power to the range and inspecting the ribbon cable between the UIB and the glass touch panel. Reseating the cable firmly into both connectors and securing the locking tabs may resolve the error. If the cable is visibly damaged or the error returns after reseating, you will likely need to replace the ribbon cable or one of the connected components.

A power reset by unplugging the range or switching off the circuit breaker for a few minutes may temporarily clear the code, but it will return if the underlying connection issue is not corrected. The error is triggered by an active hardware detection failure, so the fix requires physically inspecting and reseating or replacing the ribbon cable and associated connectors.
