Questions & Answers

For Lg Range Sub Circuit Board (Part Number: OEM16995033)

Hua for Model Number LRE 30451SB/02

The F-1 code came after I ran a self cleaning cycle. At beginning, I cleared the code by press the clear button, then tried to turn on the burners, was able to use one at a time, not two burners at same time, while the f-1 code came back in a few minutes, clear it again and again, some oven buttons worked. First attempt: Turn off the power, open the back, I cleaned ribbon cables, make sure put them back all the way in, pulled some connectors out, then back in. turn the power back, pf showed on keypad on all the burners, press on/off buttons, pf disappeared, time shows on the display, but all the other buttons are not working anymore! f-1 code comes back in a few minutes again, clear it off, comes back in a few minute..., only on/off buttons work. Second attempt: Turn off the power, disconnected the ribbon cable, turn on the power, the pf showed on all the burners, and PF showed on the display too, wait for a 5 - 10 min. the f -1 code doesn't come back! Does it mean the temp sensor is still good? Any suggestion as to which part should I try to replace first? Thanks.

Hua, The F1 error does not have anything to do with the oven sensor as being the issue. This would be a faulty touchpad that will need to be replaced.

Jan, if the igniter is glowing, then you know there is voltage present, I would replace the oven igniter, part number is MEE61841401, there has to be enough resistance for the igniter to open the gas valve.

Gerald, The unit may have the beeper volume turned down and you will want to try the following. BEEPER VOLUME 1. Press the SETTING button until “Beep” appears in the display. 2. Press the 1 button for LOUD, 2 button for NORMAL, 3 button for LOW, and press the 4 button for MUTE. 3. Press the START button to accept the change. NOTE On models with only two volume settings: Press the 1 button for NORMAL, or the 2 button for MUTE. Then press the START button to accept the change.

Gel, the ribbon harness should not have to be turned to plug it in and the top cable should not have to be either but it may need to be.

Todd, The relay should not be noisy on the control board. if the relay is noisy then it would most likely be a bad relay which would require the board to be replaced.

Emil, You will want to access the control board and make sure that the ribbon harness is seated properly with no corrosion on it. If this checks ok then the range touch control will be the most likely cause for this issue.

Kevin, The most likely cause for the 2 elements on one side to not work and the start button to not start the oven would be a faulty control board EBR74632601.
