What the -SE- error code actually means

Your Frigidaire range is showing -SE- because it detected an electrical short in the keypad or the wiring connecting the keypad to the control board. This is similar to the range thinking a button is stuck pressed, but caused by a wiring or component fault rather than a stuck key. The range locks out to protect itself, and the issue usually requires inspecting or replacing the keypad, its cable, or in some cases the main control board.

Questions people ask about -SE-

What does -SE- mean on a Frigidaire range?
The -SE- code stands for a shorted key condition. The control board has detected a short circuit somewhere between the main PCB connector CN07 and the keypad assembly, including the connecting cable. This causes the range to lock out normal operation until the fault is identified and corrected.
Is it safe to use my Frigidaire range while it shows the -SE- error?
It is not recommended to operate the range while -SE- is displayed. A short circuit in the keypad circuit can potentially cause unintended control behavior or prevent the range from responding correctly to commands. Disconnecting power until the fault is diagnosed and repaired is the safest approach.
How much does it cost to repair the -SE- error on a Frigidaire range?
Repair costs depend on which component has failed. A replacement keypad membrane or ribbon cable typically costs in the range of $20 to $80 for parts, with labor adding $75 to $150 if a technician performs the work. If the main PCB is the faulty component, the part alone can range from $100 to $300 or more depending on the model, with labor costs on top of that.
Will resetting the power clear the -SE- error on my Frigidaire range?
A power reset may temporarily clear the display, but the -SE- code will return if the underlying short circuit is still present. Because the fault is caused by a physical electrical problem in the keypad, cable, or connector, it cannot be resolved by resetting alone. A proper repair of the faulty component is required for the error to stay cleared.
How do I fix the -SE- error on a Frigidaire range?
Start by disconnecting power to the range and removing the keypad cable from connector CN07 on the main PCB. Use a multimeter to check for continuity or a short between the CN07 pins with the cable disconnected. If the short clears with the cable removed, the keypad membrane or ribbon cable is the faulty component and should be replaced. If the short remains with the cable disconnected, the main PCB requires replacement.
