How to fix error code F43 on a Kenmore Elite built-in dual electric oven, model 790.48173002?
Error code F43 on a Kenmore Elite built-in dual electric oven (model 790.48173002) typically indicates a problem with the oven's temperature sensor or the control board. Here's a step-by-step guide to troubleshoot and potentially fix the issue: 1. Check Power Supply: Ensure that the oven is properly connected to a power source and that the circuit breaker or fuse is functioning correctly. Sometimes, a power interruption can trigger error codes. 2. Wait and Reset: Turn off the oven and unplug it from the power source. Wait for a few minutes to allow the internal electronics to reset. Plug the oven back in and turn it on to see if the error code clears. 3. Inspect Temperature Sensor: The F43 error code often points to a faulty temperature sensor (also known as a thermostat or probe). Locate the sensor inside the oven. It's usually a small, slender tube-like component connected to the back wall. Check for any visible damage, loose wires, or corrosion. If you find issues, you might need to replace the temperature sensor. 4. Test Temperature Sensor: Using a multimeter, you can test the resistance of the temperature sensor. Disconnect the sensor's wires and measure its resistance at room temperature. Consult the oven's manual for the expected resistance range. If the measured resistance is significantly different, the sensor is likely faulty and needs replacement. 5. Check Control Board: If the temperature sensor seems fine, the issue could be with the oven's control board. Inspect the control board for any visible signs of damage, such as burnt components or loose connections. If you're comfortable with electronics, you might attempt to resolder loose connections or replace damaged components. Otherwise, consider seeking professional assistance. 6. Perform a Hard Reset: Sometimes, an electronic glitch can cause error codes. Perform a hard reset by turning off the oven's circuit breaker or unplugging it from the power source for about 10-15 minutes. Then, restore power and check if the error code persists. 7. Professional Help: If you're unable to diagnose or fix the issue on your own, it's advisable to contact Kenmore's customer support or a qualified appliance technician. They have the expertise to diagnose and repair complex electrical and electronic components safely. Remember that working with electrical appliances carries risks, and if you're not confident in your skills, it's better to seek professional help to avoid further damage or safety hazards.
