What F36 means

On LG electric and gas ranges with a numeric F-code display, F36 is listed as a transistor error. A transistor is a switching part on a control board that turns power on and off for something in the range. F36 means the control found a problem with one of those switches. The range may stop a function, and the display shows the code. The combined range list gives only the words transistor error.

Common causes of F36

  • A switching transistor on a board that is not working
  • A board connection that is loose
  • A power event that stressed the board
  • A control board that needs replacement
✓ One safe check you can try

1. Switch the circuit breaker off for 30 seconds, then on again. 2. Try the function once more. 3. If F36 shows again, leave the range alone and call us. 4. Leave the control panel closed and do not remove any covers. 4. Keep the control panel and the oven door clear of spills until we arrive.

! Why to stop there
  • A transistor error lives on a board, so we confirm which board before ordering one.
  • We check the supply and the connections first, because a loose connection would not need a new board.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F36F36 questions
What is a transistor error on a range?

The control found a problem with an electronic switch that turns power on and off. It is a board-level problem. The transistor is a small electronic switch on a board.

Can I fix F36 myself?

Not safely. The board sits in the control area, and you should not open it. The breaker reset is the only home step. Leave all covers closed and let us look at it.

Will a reset clear F36?

A reset may clear it if it was a one-time event. If F36 returns, the board needs testing. If F36 comes back, we test the board.
