Frigidaire Range Error Code F7 00

F7 00 means the range has detected a missing communication connection between the Potentiometer/Display Board and the User Interface Board (UIB). The signal travels through the ESEC harness, and a break anywhere along that path will trigger this code. It is not a combustion or safety fault, but it does indicate a control system failure that needs to be diagnosed. A technician will typically start by inspecting the ESEC harness and connectors before evaluating the boards.

F7 00 points to a control communication fault rather than a gas leak or direct heating element failure, but using the range with an active control board error is not recommended. The fault may affect the accuracy or reliability of your burner controls. It is best to stop using the range until the issue is diagnosed and repaired to avoid unpredictable behavior from the control system.

Repair costs depend on what component has failed. If only the ESEC harness needs replacement, parts and labor costs are typically on the lower end, generally in the range of $75 to $200 depending on your location and technician rates. Replacing the UIB or Potentiometer/Display Board adds parts cost, and total repair expenses for a board replacement can range from $150 to $400 or more. Getting a diagnosis first will help clarify exactly which part is at fault before committing to a repair.

A knowledgeable DIYer can start by checking the ESEC harness for loose connectors, visible damage, or corrosion, which sometimes resolves the fault without any parts. However, if the harness looks intact, diagnosing and replacing the UIB or Potentiometer/Display Board requires familiarity with appliance electronics and accessing internal components. If you are not comfortable working inside the range, a qualified appliance technician is the safer option. The technical support line for Frigidaire can also provide additional guidance if basic connector checks do not resolve the issue.

Power cycling the range by disconnecting it from power for a few minutes may temporarily clear the code, but if the underlying connection problem or component failure still exists, the error will return. A reset does not repair a damaged harness, corroded connector, or failed board. Clearing the code should only be considered a temporary step while arranging for a proper diagnosis.
