What the F5 01 error code actually means

Your Frigidaire range has detected that one of its internal control boards, the one that manages power to the cooktop burners, has stopped communicating with the main control panel. This is typically caused by a loose wire connection or a faulty control board. The range may not operate safely until this issue is resolved.

Questions people ask about F5 01

What does F5 01 mean on a Frigidaire range?
F5 01 indicates that the ESEC Power Board, which controls power to the surface heating elements, is not communicating with the User Interface Board. The fault is detected when the communication link between these two components is interrupted. It can be caused by a faulty harness connection, a failed Power Board, or a defective UIB.
Is it safe to use my Frigidaire range while F5 01 is displayed?
Because F5 01 indicates a loss of communication with the board that controls power to the surface elements, the range should not be relied on for safe, normal operation while this fault is active. Avoid using the cooktop until the underlying issue has been diagnosed and repaired.
How much does it cost to repair a Frigidaire range showing F5 01?
Repair costs depend on which component has failed. If only a harness connector needs reseating or cleaning, the cost may be minimal. Replacing a UIB or ESEC Power Board typically ranges from around $150 to $400 or more depending on parts and labor costs in your area.
Can I fix F5 01 on my Frigidaire range myself?
A knowledgeable DIYer can start by inspecting the ESEC wiring harness for loose or corroded connectors, which is a common cause of this fault. However, if the harness looks intact, isolating whether the UIB or the Power Board has failed typically requires further technical diagnostic support. Frigidaire recommends contacting their technical assistance line before replacing boards.
Will resetting my Frigidaire range clear the F5 01 error?
Power cycling the range by disconnecting it from power for a few minutes may temporarily clear the fault, but the code will typically return if there is an underlying hardware problem with the harness, UIB, or Power Board. A reset is not a substitute for a proper diagnosis.
