Frigidaire Range Error Code F7 30

F7 30 indicates that the potentiometer for the Right Rear burner has an open circuit. The potentiometer is a position sensor in the burner knob assembly that communicates the knob's setting to the control board. When this sensor loses electrical continuity, the range cannot detect the Right Rear burner position and triggers this fault code.

Using the Right Rear burner while this fault is active is not advisable, since the control board cannot reliably read that burner's position. Other burners on the range may continue to function normally, but you should confirm this carefully. If the range displays erratic behavior or the fault affects multiple zones, discontinue use and have it inspected promptly.

If only the Right Rear potentiometer needs replacement, parts typically range from around $20 to $60 depending on the model, with professional labor adding $80 to $150 or more. If the User Interface Board is determined to be at fault, board replacement can bring total repair costs to a range of $150 to $350 or higher. Getting a diagnostic estimate from a qualified technician before committing to parts is a good practice.

A knowledgeable DIYer can begin by inspecting the Right Rear burner knob area for disconnected wiring or a loose connector, which may resolve the issue without parts. If the wiring is intact, testing the potentiometer for continuity requires a multimeter and some disassembly of the cooktop knob area. Replacing the potentiometer is a moderate-difficulty repair, but if the User Interface Board is involved, professional service is strongly recommended.

Resetting the range by cycling the power at the breaker may temporarily clear the fault code display, but the underlying open circuit condition in the potentiometer will cause it to return. A reset alone does not repair the failed component or wiring. The fault will persist until the root cause is identified and corrected.
