Frigidaire Range Error Code F7 01

F7 01 indicates a missing connection between the Potentiometer/Display Board and the User Interface Board (UIB) in the ESEC circuit. The range has detected that communication between these two components has been lost. This can be caused by a loose harness connector, damaged wiring, or a failed board. Diagnosis starts with inspecting the ESEC harness connections.

Operating the range with an active F7 01 code is not recommended. Because this error indicates the control knob sensing circuit is not communicating properly with the User Interface Board, the range may not respond accurately to your input. This creates an unpredictable cooking environment and could pose a safety risk, particularly if burner control is affected.

If the issue is simply a loose connector, the repair can be completed at no parts cost. If the ESEC wiring harness needs replacement, parts and labor typically run in the range of $75 to $200 depending on the model and local labor rates. Replacing the UIB or the Potentiometer/Display Board generally costs between $150 and $400 or more including parts and professional labor.

A power reset by unplugging the range for a few minutes or shutting off the breaker may temporarily clear the code, but it will return if the underlying connection problem is not fixed. If the fault is caused by a loose connector that reseats itself, the code might not immediately return. However, any physical damage to the harness, connectors, or boards will cause the error to come back.

A knowledgeable DIYer can check the ESEC harness connectors for loose or corroded connections, which is the most common cause and requires no replacement parts. If the harness appears fine, diagnosing whether the UIB or the Potentiometer/Display Board has failed typically requires more advanced testing and the Frigidaire technical support line is recommended for further guidance. Board replacement is within reach for experienced DIYers but should be approached carefully.
