Hello, would appreciate some pointers on this issue. Our electric LG range (lre3023st) has a dual burner which started having issues. It would heat when I turn it on the smaller setting (the inside radius); however, when I turn on the full setting (both inside and outside radius), the burner doesn't heat (both inside or outside radius don't work). I have tried replacing the burner itself and that didn't help. All other burners, stove, etc. work fine. The control panel also seems to work fine (lights, etc.).

Thanks for your help.

I cannot find any tech info on this model so cannot be helpful.

Below is a site that has manuals

There are a couple LG manuals (LRE30451 and LRE30755) which may at least point you in the right direction.
With luck there will be some commonality with your unit.

Hopefully you have the tech sheet as this is one complicated piece of gear.

Note: You cannot assume that the control panel/board is OK as only the section that controls that specific burner may have gone belly up.
I am not even sure where the actual control electronics for that burner is as it looks like it has a display board that fees to another board.
