For your LG range model LSEL6335F/00, one of the first things to check is whether the relay control board (AP7013143) is receiving the proper voltage. The control board is located on the back of the unit.

:warning: Use caution when working around live voltage. If you’re not comfortable performing electrical tests, contact a qualified service technician.

Check Incoming Power to the Control Board

  1. Locate TAB09 (red wire, L1) on the control board.

    • Measure from TAB09 to ground.

    • You should read approximately 110–120 VAC.

  2. Locate TAB01 (black wire, L2).

    • Measure from TAB01 to ground.

    • You should also read approximately 110–120 VAC.

If both readings are correct, the control board is receiving proper power.

Check the Broil Circuit

  1. Turn the oven on to Broil.

  2. Measure across TAB08 and TAB02 (both gray wires).

You should read approximately 220–240 VAC across these two terminals when Broil is selected.

  • If you do not have approximately 220–240 VAC across TAB08 and TAB02, the broil relay on the control board has likely failed, and the control board (AP7013143) will need to be replaced.

  • If you do have approximately 220–240 VAC across TAB08 and TAB02, the control board is supplying the proper voltage. Next, verify that the same 220–240 VAC is present across the two terminals of the broil element [AP6337106] to rule out a wiring issue between the control board and the element.

    • If 220–240 VAC is present at the broil element and the element is not heating, the broil element has failed and will need to be replaced.

Check the Bake Circuit

  1. Turn the oven on to Bake.

  2. Measure across TAB07 and TAB18.

You should read approximately 220–240 VAC across these two terminals when Bake is selected.

  • If you do not have approximately 220–240 VAC across TAB07 and TAB18, the bake relay on the control board has likely failed, and the control board (AP7013143) will need to be replaced.

  • If you do have approximately 220–240 VAC across TAB07 and TAB18, the control board is supplying the proper voltage. Next, verify that the same 220–240 VAC is present across the two terminals of the **bake element [**AP6837264] to rule out a wiring issue between the control board and the element.

    • If 220–240 VAC is present at the bake element and the element is not heating, the bake element has failed and will need to be replaced.

These tests will help determine whether the issue is with the incoming power, the control board relays, the wiring between the board and the elements, or the heating elements themselves.
