Electric Range: “F-9” error code
If your oven control beeps and displays any F code error the electronic control has detected a fault condition. Turn the Oven mode knob to the Off position to clear the display and stop beeping. Reprogram oven if fault recurs, record fault number. Turn the Oven mode knob to the Off position and call for service.
Cause and Symptoms
- Code F-3 - caused by key short error
- Code F-9 - caused by oven not heating
PLEASE NOTE
An F-9 error code on an LG electric range means that the oven failed to heat up to 150°F after five minutes of preheating. Some possible causes include -
- short-circuited element,
- defective relay printed circuit board,
- defective relay connector, and
- an electrical fault that magnetized the circuitry.
Regrettably, the only course of action is a repair service.
Try this
- Should the LG electric range be beeping alerting customer to some malfunction, seek error code display in control panel window.
- If the Control Panel Display lights up error code “F-9” it means the oven failed at exceeding 150 degrees Fahrenheit after 5 minutes of preheating.
- Press the Clear/Off button to terminate the beeping alarm.
- Try to reset the unit by either unplugging the range or tripping circuit breaker to “off” position then switching it back "on" again.
- Leave it “as is” (resting unplugged or out of power) for 3 to 5 minutes then re-plug or switch breaker back “on”.
- Either the range has been reset and will operate normally moving forward or;
if the “F-9” error code persists, a service technician will need to be dispatched.
Resetting the range once is executed in the hope of demagnetizing electronic circuitry that could have inadvertently generated this error code.
Flea power is residual static electricity that remains within an electronic device or appliance’s Printed Circuit Board even after it has been powered off, often causing erratic behavior from the device. Draining residual flea power, also known as performing a "hard reset", is also a common troubleshooting step in eliminating erroneous error codes that might have popped up in the control panel display window.
Gas Range: “F-9” error code
Possible causes for oven not heating can either be a short-circuited element, a defective relay printed circuit board or defective relay connector. Other than dispatching an authorized service technician to repair the range, there is no other possible troubleshooting.
Cause and Symptoms
- Code F-3 - caused by key short error
- Code F-9 - caused by oven not heating
Try this
If your oven control beeps and displays any F code error :
- Check the main gas shut-off valve or the oven gas shut-off value and call for service.
- Remove the power from the range for five minutes and then reconnect the power. If the function error code repeats, call for service
