LG Oven Error F16: Oven Sensor Reading Out of Range

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

LG oven error F16 usually means the oven temperature sensor is reading outside the expected range.

Severity

Medium - some user checks may help, but repeated faults often need service.

Can you fix it yourself?

Partial — start with DIY steps

Most likely cause

Temperature sensor harness connector has come partially loose — causing an intermittent or out-of-range reading

Estimated time for safe first checks: 15–30 min for sensor check and replacement.

Step-by-Step DIY Fix Guide

  1. SAFETY: Disconnect power at the breaker before checking the sensor or its connector.
  2. If your model allows safe sensor access, pull the oven temperature sensor forward carefully and reseat the wiring connector.
  3. Make sure the sensor probe is mounted correctly against the back wall and not hanging loose.
  4. Restore power and run a short bake test only after the connection is secure again.
  5. If F16 returns, stop there and compare the sensor reading with your model specification before ordering parts.

If F16 comes back after reseating the sensor

  • A repeat F16 after the connector is secure usually points to a sensor that has drifted out of range.
  • If the sensor tests within spec but the code still returns, the control board becomes more likely than a loose connection.
  • If F16 appears intermittently, compare whether it happens only after the oven warms up.

What This Error Means

LG oven error F16 means the oven does not trust the temperature reading it is getting from the sensor. That makes F16 more of a sensor-range problem than a general heating error.

The least invasive starting point is still the sensor connection. A loose harness or a sensor that has drifted out of range is more common than a major board failure.

If the sensor connection is secure and F16 returns, the next likely issue is the sensor itself rather than the user setup.

Most Likely Cause by Symptom

The code appears during normal baking but the oven does not seem dangerously hot.

Likely cause: The sensor reading is drifting or out of range rather than the oven truly overheating.

Check first: Check the sensor connection before assuming a relay or board problem.

The code clears briefly after a reset, then returns later.

Likely cause: A weak sensor or intermittent connector is failing again once the cavity warms.

Check first: Reseat the sensor connector and compare the behavior on a short bake test.

Common Causes

  • The oven temperature sensor connector is loose.
  • The sensor has drifted out of range and no longer reads accurately.
  • The sensor wiring is damaged or not seated correctly.
  • A previous repair or movement disturbed the sensor probe position.
  • The control board is misreading a normally good sensor.

What Not to Do

  • Do not keep restarting bake cycles if F16 returns repeatedly.
  • Do not force the sensor wiring or let the connector fall back into the insulation cavity.
  • Do not jump straight to control-board replacement before the sensor path is checked.

Model and Display Variation Notes

Model-family notes

  • LG oven temperature-sensor layouts vary by cavity and range family, but F16 still points first to the sensor path.
  • This is different from a true overheating code, so compare F2 instead if the oven appears to be running dangerously hot.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Common parts

  • Oven temperature sensor/thermistor if sensor has drifted or failed ($15–$40)

Manual and model check

Check your exact model and manual before ordering any LG oven parts.

Service option

Service visit if F16 returns after the sensor path is checked.

When Not to Keep Troubleshooting

F16 returns after the sensor connector is reseated and the oven is restarted.

  • The sensor tests correctly but the code still comes back.
  • You are not comfortable checking the sensor wiring safely at the breaker.

How to Prevent It Recurring

  • When cleaning the oven cavity, avoid knocking or bending the temperature sensor probe — it is fragile and even minor bending affects its calibration
