What does the F23 error mean?

The F23 error on a Frigidaire electric range usually indicates a communication issue between the oven’s user interface board and the glass touch panel control.

The user interface board receives signals from the touch panel and controls the range’s functions. To work correctly, the board and touch panel must maintain a seamless conversation. If this connection is disrupted, the board sends a warning to the user in the form of an F23 error.

Safety tips

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot the F23 error

Follow these steps to resolve the F23 error on your electric Frigidaire range.

Step 1: Reset the power

1. Unplug the range from the power outlet.
2. Let the range remain unplugged for at least 2-3 minutes before plugging it back in.
3. See if the F23 error code reappears after the power reset.

If the F23 error code doesn’t return, then you may have resolved a temporary communication problem.

If you’re still seeing the F23 error, move on to the next step.

Step 2: Check the wire harness

1. Make sure the range is unplugged from the power outlet.
2. Find the wire harness that connects the user interface board and touch panel, which is usually denoted as I2C1 and I2C2 in the unit’s wiring diagram.
3. Carefully examine the wire harness and its connections on both ends for any splits, kinks, loose fittings or burn spots that could break conductivity. Gently flex the harness while observing it under a bright light to check for the tiniest problems. If you find any damage, replace the wire harness.
4. Set a multimeter to continuity mode.
5. Place a multimeter lead on each end of the wire to check it for continuity. The meter should make a beeping sound if there’s continuity.

If you don’t get continuity, replace the wire harness. If you got continuity, continue troubleshooting.

Step 3: Check voltage

LIVE VOLTAGE WARNING: For this test, the range needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Make sure the range is plugged in.
2. Set a multimeter to VAC.
3. Check your model’s technical sheet to find the specific locations to check on the control board.
4. Use the multimeter probes to check the control board input for 120 VAC.

If you get an abnormally high or low voltage, check the power receptacle and power cord.

If you don’t get 240 VAC at the receptacle, you’ll need to contact a licensed electrician to repair the power supply.

If you get 240 VAC at the receptacle and all other checks and inspections are good, replace the touch panel control.

If replacing the touch panel control doesn’t fix the error message, replace the user interface board as a last resort.
