What Does Error F7 Mean?

The LG oven F7 error indicates a convection fan malfunction, where the oven's diagnostics fail to detect fan operation during expected activity. This results in inconsistent cooking performance, with the oven potentially not reaching set temperatures. Common symptoms include the F7 error appearing during preheating or convection mode, and convection baking may become non-functional while conventional bake remains operational. Possible causes are a faulty convection fan motor, temperature sensor issues, or heating circuit problems.

Common Symptoms:

  • F7 displays when the oven is trying to preheat or run a convection mode but doesn’t detect fan operation.
  • Oven may fail to heat to set temperature.
  • Convection baking may not function while conventional bake still works (from community reports).

Possible Causes

  • Convection fan motor failure or obstruction (medium)
  • Temperature sensor or heating circuit related to convection mode (medium)

How to Fix Error F7

DIY Fix Basic checks and reset

  1. Turn off the oven and disconnect power at the breaker or unplug.
  2. Wait a few minutes and restore power to reset internal diagnostics.
  3. Attempt a simple reheating cycle to see if F7 recurs.

Technician Only Inspect and test convection fan and related components

  1. With power off, remove oven back or access panel to locate the convection fan.
  2. Visually inspect the fan for obstructions, damage, or seized bearings.
  3. Check wiring connections to the fan and control board for continuity and secure fit.
  4. Use a multimeter to test fan motor operation.
  5. If fan motor fails, replace the convection fan assembly.
  6. If fan tests fine, test temperature sensors and heating elements; verify preheat reaching ~150°F.
  7. Inspect control board outputs to fan and heating circuits; replace control board if defective.

Parts needed: Convection fan motor, Temperature sensor (thermistor), Heating element, Control board

🛑 When to Call a Pro:
  • If the F7 error persists after reset and basic checks.
  • If the user is uncomfortable performing internal inspections with power disconnected.
  • If multiple components (fan, sensor, board) appear to be failing simultaneously.
