Direct answer
On the covered LG range or oven, F16 means an Oven Sensor Issue — LG's own wording. First, record the code and the cycle in use.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- LG range or oven covered by the cited source
- Displayed code or documented alias: F16
- The exact operating state described by the manufacturer
What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair
Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers F16 on LG electric and gas ranges and wall ovens. LG documents radiant-cooktop codes separately in the same article; griddle, induction and sous-vide codes apply only to models with those features.
Preserve the failure state
ReversibleRecord the code and the cycle in use. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversiblePress the CLEAR/OFF key and try the original function again; if the code reappears, switch the unit's circuit breaker off for 30 seconds before switching it back on — LG's own sequence. Do not borrow a reset or meaning from a similar code, product or model year.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If F16 returns, stop repeated resets and use model-specific manufacturer support.

What does F16 mean on a LG range or oven?+
an Oven Sensor Issue — LG's own wording.
Can I reset F16 without fixing the cause?+
A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
LG states that if the problem continues, or the troubleshooting steps cannot be performed, the unit requires service.
