Frigidaire Range Error Code F16

F16 means the oven's user interface board is unable to read the potentiometers, which are the variable resistor components connected to the control knobs. The board relies on specific resistance signals from these components to know what position each knob is in. When those signals are missing or out of range, the board faults and displays F16. This can result from a knob left in an active position, a wiring issue, or a failed potentiometer or board.

It is not recommended to continue using the range while F16 is active, as the control board cannot reliably read the knob positions, which means heating functions may not respond accurately. Operating the appliance in this state could lead to unintended heating behavior. Perform the recommended reset first, and if the fault persists, have the range inspected before further use.

If the fix is just a power reset, there is no parts cost involved. Replacing a faulty potentiometer typically runs in the range of $20 to $80 for the part, depending on the model. A new user interface board is more expensive, generally ranging from $100 to $300 or more for the part alone. Adding professional labor can bring the total repair cost to between $150 and $450 depending on which component needs replacement and your location.

In many cases, yes. Start by turning all control knobs fully to the OFF position, then disconnect the range from power for 30 seconds before restoring it. If the error clears and does not return, no further action is needed. If the fault comes back, additional diagnosis of the potentiometers and wiring will be required, which may be within reach of a confident DIYer but could also call for professional service.

A power reset will clear F16 if the root cause was simply a potentiometer left in an active or mid-range position. Turn all knobs to OFF, cut power at the breaker or by unplugging the unit, wait 30 seconds, and restore power. If the underlying cause is a failed potentiometer or damaged wiring, the code will return after the reset and parts or repairs will be needed.
