Frigidaire Range Error Code F7 22

F7 22 means the control board has detected that the potentiometer for the left rear burner is sending a value outside the expected range. The potentiometer is the sensor inside the knob that communicates the dial position to the User Interface Board. This code points to a problem with that sensor, its wiring, or the board itself. Moisture in the control panel area is also a known contributing factor.

It is best to avoid using the left rear burner while this fault is active, as the control board cannot reliably read the knob position and may not regulate that burner correctly. Other burners may still function normally depending on how the range responds to the fault. Do not ignore the error code, as continued use with a faulty sensor could lead to unintended burner behavior.

Repair costs vary depending on the root cause. A replacement potentiometer is typically an inexpensive part, often in the range of $15 to $60 depending on the model. If the User Interface Board requires replacement, parts alone can range from $100 to $300 or more. Adding professional labor, total repair costs can range from $100 to $400 or higher, which is why confirming the exact failed component before ordering parts is important.

A knowledgeable DIYer can attempt to resolve this by inspecting the left rear knob area for moisture or visible connector issues and reseating any loose connectors. If those steps do not clear the fault, replacing the potentiometer is the next step, which requires disassembling part of the control panel. More complex repairs involving the UIB are generally better handled by a qualified technician, and Frigidaire recommends contacting their technical line if the fault persists.

Resetting the range by powering it off at the breaker for a few minutes may temporarily clear the code, but the fault will return if the underlying problem is not corrected. If moisture caused the reading, allowing the control panel to fully dry out before restoring power may resolve the issue. A persistent F7 22 after reset indicates a component failure that requires inspection and likely parts replacement.
