Frigidaire Range Error Code F15

F15 indicates an internal control or power supply failure between the Power Supply Board and the Electronic Oven Control (EOC). The two boards communicate through a wiring harness connected at the P2 and J2 connectors, and a breakdown anywhere along that path triggers this fault. The issue can stem from a loose connector, a damaged harness, or a failed board.

A persistent F15 fault means the control system cannot confirm reliable communication between its core boards, which may prevent the oven from operating correctly or predictably. It is best to avoid using the range until the fault is diagnosed and resolved, as control system failures can lead to unpredictable behavior.

If only the harness connectors need reseating, there is no parts cost. A replacement Power Supply Board typically costs in the range of $75 to $200 depending on the model, and a replacement EOC can range from $150 to $350 or more. Adding professional labor will increase the total repair cost, generally by $100 to $200 depending on your area.

Checking and reseating the harness connectors at P2 and J2 is a repair most experienced DIYers can attempt after unplugging the range. However, if a board replacement is needed, you must be comfortable working with control electronics and sourcing the correct model-specific part. If you are unsure, a qualified appliance technician is the safer choice.

Resetting the range by unplugging it for a few minutes may temporarily clear the display, but if there is an underlying hardware problem such as a loose connector or a failing board, the F15 code will return. A reset alone is not a fix, but it can help confirm whether the fault is intermittent or persistent.
