Quick answer
LG lists F5 as a lower oven thermistor error. Press CLEAR/OFF and retry, then reset the breaker if it returns.
Model compatibility: LG reuses codes across series and model years, so F5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F5 means a lower oven thermistor error on LG ranges and ovens.
Seeing F5 on the display? LG’s table for cooktops and ranges defines it as a lower oven thermistor error.
The reset LG recommends

Repeat the original function.
If the same code comes back, cut power at the circuit breaker and wait 30 seconds.
Restore power at the breaker.
Where F5 applies
Both range and oven controls can show it, and LG ties it to no named series.
When the code stays on
Past the reset, there is nothing more for the owner to do; a code that stays calls for service.
