Frigidaire Oven Error Code F2

The F2 code indicates a communication failure in the oven's control system. It includes sub-fault F21, which is a communication problem between the main controller and the auxiliary board, and F23, which signals a communication problem between the main controller and the TST board or glass touch panel. The oven detects that data is not being exchanged properly between these components and displays the fault to alert you.

You should not attempt to use the oven while the F2 fault is active. The communication failure means the main controller cannot properly coordinate with the auxiliary board or touch panel, which could result in unpredictable behavior or the oven failing to respond correctly to temperature controls. It is best to resolve the fault before resuming cooking.

Repair costs vary depending on the cause. If the fix involves reseating a connector or repairing a harness, costs are minimal, primarily covering your time or a basic service call fee ranging from around 75 to 150 dollars. If an auxiliary board or TST glass panel board needs to be replaced, parts alone can range from roughly 100 to 300 dollars or more, plus labor if a technician performs the repair.

In many cases, yes. Start by unplugging the oven and inspecting the wiring harness and connectors between the main controller, auxiliary board, and glass panel, specifically connectors P4, P10, P1, and J1. Reseating a loose connector or identifying a visibly damaged wire is a repair many technicians and experienced DIYers can perform. If the wiring is intact and the fault persists, board replacement may be needed and requires more comfort with appliance electronics.

A reset, done by unplugging the oven for a few minutes and restoring power, may temporarily clear the F2 code if the fault was caused by a transient glitch in the communication signal. However, if there is an underlying wiring problem or board failure, the code will return. A reset alone is not a repair and should be followed by a proper diagnostic inspection of the wiring and connectors.
