Name: LG LSGL6337F
Brand: LG

Question 1

What does error code F-1 mean on LG LSGL6337F?

Accepted Answer

Opened Sensor — oven thermistor (sensor) remains open for over 1 minute during cooking. Cause: Disconnected or loose oven sensor connector; Broken oven temperature sensor wiring; Failed oven temperature sensor (thermistor); Loose CN6 connector on Main PCB.

Question 2

What does error code F-10 mean on LG LSGL6337F?

Accepted Answer

Door Lock Fail — door locking motor failure during self-clean or lock operation. Cause: Loose or disconnected terminal on micro switch or door lock motor; Failed micro switch (normally open type); Failed door lock motor; Loose CN06 connector on Main PCB; Failed Main PCB.

Question 3

What does error code F-2 mean on LG LSGL6337F?

Accepted Answer

Shorted Sensor — oven thermistor is shorted for over 1 minute during cooking. Cause: Shorted oven temperature sensor (thermistor); Pinched or shorted sensor wiring; Failed Main PCB.

Question 4

What does error code F-27 mean on LG LSGL6337F?

Accepted Answer

Stalled Fan Lock Error — cooling fan is stalled during self-clean cycle. Cause: Failed cooling fan motor; Loose or disconnected cooling fan wiring.

Question 5

What does error code F-3 mean on LG LSGL6337F?

Accepted Answer

Key Shorted Error — one or more control keys continuously shorted for over 60 seconds. Cause: Stuck or mechanically jammed key on control panel; Control Lock active (user error); Wiring fault to Touch film or Main PCB.

Question 6

What does error code F-6 mean on LG LSGL6337F?

Accepted Answer

Oven Hot — oven temperature exceeds 650°F continuously for 2 minutes during cooking (excludes self-clean). Cause: Relay on Relay/Power PCB stuck closed (heater circuit permanently on); Failed oven temperature sensor reading too low; Wiring fault causing relay to stay energized.

Question 7

What does error code F-7 mean on LG LSGL6337F?

Accepted Answer

Convection Fan Error — convection fan operation cannot be detected for over 1 minute during any mode requiring the upper convection fan. Cause: Loose or disconnected convection motor wiring connector; Failed convection motor; Loose connection between CN4 of Power PCB and CN1 of Main PCB; Failed Main PCB or Power PCB.

Question 8

What does error code F-8 mean on LG LSGL6337F?

Accepted Answer

Shorted Probe Sensor — oven meat probe sensor short error. Cause: Probe touching the oven side panel (metal-to-metal short); Incorrect wiring (white and black wires swapped); Failed probe sensor; Failed Main PCB.

Question 9

What does error code F-9 mean on LG LSGL6337F?

Accepted Answer

No Heating — oven starting temperature does not exceed 150°F and oven temperature does not rise above starting temperature for over 5 minutes during preheating, with door closed. Cause: Loose or disconnected wiring at Relay PCB; Failed bake or convection igniter; Gas valve (safety valve) not opening; Failed oven temperature sensor giving false low reading.
