How to fix Kenmore oven F4 error code?

The F4 error code on a Kenmore oven typically indicates a problem with the oven temperature sensor or the associated wiring. This error code signifies that the oven is detecting an out-of-range temperature reading. Here's a step-by-step guide to help you diagnose and potentially fix the F4 error code issue: 1. Safety First: * Ensure the oven is turned off and unplugged before attempting any repairs to prevent electrical hazards. * Inspect the Oven Temperature Sensor: * The oven temperature sensor, also known as the oven probe or thermostat, is usually located inside the oven cavity, often near the upper rear wall. * Inspect the sensor for any visible damage or signs of wear. Check for disconnected wires or any signs of corrosion. 2. Test the Oven Temperature Sensor: * Use a multimeter to test the resistance of the temperature sensor. Disconnect the sensor's wires and measure the resistance between the sensor's terminals. Consult the oven's user manual for the correct resistance values at specific temperatures. * If the resistance readings are significantly different from the expected values, the sensor may need to be replaced. 3. Check Wiring Connections: * Inspect the wiring harness and connections leading to the temperature sensor. Make sure they are securely connected and not damaged. 4. Inspect the Oven Control Board: * A faulty oven control board could also trigger the F4 error code. Inspect the control board for visible damage or signs of burnt components. 5. Power Cycle the Oven: * Turn off the oven and unplug it from the power source for a few minutes. Plug it back in and turn it on to see if the error code clears. 6. Replace the Oven Temperature Sensor: * If the temperature sensor is damaged, has incorrect resistance readings, or is disconnected, it may need to be replaced. Order a replacement sensor compatible with your Kenmore oven model. 7. Professional Assistance: * If you're not comfortable performing these steps yourself or if the issue persists after attempting these troubleshooting steps, consider seeking assistance from a professional appliance technician. They can diagnose the problem accurately and make the necessary repairs. Keep in mind that diagnosing and fixing appliance issues can be complex, and electrical components can pose safety risks. If you're unsure about any step or encounter difficulties during the process, it's advisable to consult the oven's user manual or seek professional help to ensure safe and effective repairs.
