Frigidaire Range Error Code F68

F68 on a Frigidaire range indicates a high voltage condition where L1 or L2, the two hot legs of the 240-volt supply, may be crossed with the neutral conductor in the incoming power supply. The range's control system detects that voltage relationships are outside normal parameters and shuts down to prevent damage. This is primarily a wiring fault rather than an internal component failure.

Resetting the range by cycling power may temporarily clear the F68 code, but the fault will return if the underlying wiring problem has not been corrected. The error is triggered by the actual voltage condition present at power-up, so a reset alone is not a fix. The incoming power supply wiring must be verified and corrected first.

If the fix is simply rewiring the power cord or correcting connections at the terminal block, costs are typically minimal, generally in the range of $50 to $150 for a service call plus any parts needed. If the outlet or home wiring requires correction by an electrician, expect costs in the range of $100 to $300 or more depending on the extent of the work. In the uncommon situation where the control board itself is at fault, board replacement can add $150 to $400 or more in parts and labor.

No, you should not attempt to use the range while F68 is active. A crossed neutral and hot leg creates an abnormal voltage condition that can damage the control board and other components, and poses a potential shock or fire hazard. Disconnect power to the range and have the wiring inspected before resuming use.

If you are comfortable working with electrical panels and using a multimeter to check voltage and polarity, you can inspect the range's terminal block connections yourself after disconnecting power. However, if the issue is traced to the wall outlet, junction box, or home wiring, a licensed electrician is required to make those corrections safely. Any work involving 240-volt circuits carries serious shock risk and should only be done by those with appropriate knowledge and tools.
