How do I know this rack fits my LG range?

Match the part number MHL63411403 to the one listed in your range's manual or on the sticker inside the oven door. LG uses different rack widths across lines, so a rack from another model may not seat in the guides.

Is this the same rack that came with my range?

It is LG's standard oven rack for the ranges that list this part number, so it matches the original in size and wire layout. Ranges sold with a telescopic or split rack use a different part.

Can I use it for broiling?

Yes. It is a standard flat rack meant for baking and broiling positions, and it holds a broiler pan directly. Slide it to the position your manual gives for broiling.

How many racks come with it?

One rack. Order two if you want to bake on two levels at once.

How should I clean it?

Wash it by hand with warm soapy water, or leave it in the oven during a self-clean cycle if your manual allows racks in the cavity. Avoid harsh abrasive pads, which dull the chrome.
