Frigidaire Range Error Code F5 02

F5 02 indicates that the User Interface Board is not communicating with the Power Board or ESEC system. This communication failure prevents the range from processing control inputs normally. The fault can originate in the wiring harness connecting these components or in the boards themselves.

With an active communication fault between the control boards, the range may not respond to commands correctly or may behave unpredictably. It is best to avoid using the range until the fault is diagnosed and resolved to prevent potential safety issues.

Repair costs vary depending on which component has failed. A wiring harness replacement typically falls in a lower cost range, while replacing a UIB or Power Board can run anywhere from moderate to higher costs depending on the specific part and labor rates in your area. Getting a diagnostic service call first is the most reliable way to estimate the total repair cost.

A homeowner comfortable working with appliances can start by checking for loose or disconnected connectors on the ESEC harness after unplugging the range. However, if the harness appears intact, diagnosing which board has failed typically requires technical expertise, and Frigidaire recommends contacting their technical support line for further assistance at that point.

Disconnecting the range from power for a few minutes and restoring it can clear the code if the fault was caused by a temporary electrical glitch. If the code returns after the reset, a physical problem with the harness, UIB, or Power Board is likely present and will need to be addressed.
