LG Range F36 Error Code

F36 is an internal electronics fault category, not a homeowner-repair code. Record the display, check only for external electrical warning signs, use LG’s reset once, and request service if it returns.

Applies to LG range or induction cooking appliance

What the appliance detected

Detected condition

LG says F36 indicates a transistor error.

What may contribute

Possible causes

  • A temporary electronic condition that clears after the supported reset.
  • An internal power-electronics condition detected by the appliance.
  • A board, power module, connection, wiring, or related electronic issue requiring professional diagnosis if F36 returns.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record F36 and recent events

    • Photograph the code and note whether it followed a power interruption, installation, or unusual cooking event.
    • Record the full model number without removing covers.

  2. Stop for electrical warning signs

    • Stop using the appliance for sparking, burning odor, scorching, unusual heat, repeated breaker trips, or visible electrical damage.
    • Do not touch damaged wiring or attempt to open electronic enclosures.

  3. Reset once, then escalate

    • Turn the range circuit breaker off for 30 seconds and restore power once, as LG directs.
    • If F36 returns, keep the appliance off and request appliance service.

Actions not recommended

  • Do not open power-electronics, inverter, induction, or control enclosures.
  • Do not probe transistors, boards, capacitors, wiring, or live voltage.
  • Do not replace a board or power module based on F36 alone.

When to stop and request service

  • Request appliance service if F36 returns after one documented reset.
  • Use a licensed electrician if F36 accompanies broader household supply problems or repeated breaker trips.
  • Stop immediately for smoke, sparking, burning odor, scorching, unusual heat, or visible electrical damage.
