LG Oven Error Code F8 — Key Shorted / Meat Probe Error
What this means
The F8 error code can indicate one of two issues: a control panel touchpad key that is continuously shorted for over 60 seconds, or a meat probe sensor error. If a key is stuck, the touchpad or control board may be failing. If it is a meat probe issue, the probe may be damaged, improperly connected, or the jack may have residue preventing proper contact.
Step-by-step fix
3 stepsReset the oven
Press CLEAR/OFF. Turn off the circuit breaker for 30 seconds, then turn it back on.
Check the control panel
Look for stuck buttons or moisture on the touchpad. Wipe the control panel dry with a soft cloth.
Steam from cooking can cause moisture buildup on the control panel, creating false key presses.
Check the meat probe
If a meat probe is connected, remove it from the jack. Clean the probe tip and the jack with a dry cloth. Reinsert or leave disconnected to test.
When to call a professional
If the touchpad is failing internally, the control panel overlay or control board may need replacement.
