Need replacement oven cavity

I need a replacement oven cavity for my LG Kitchen Range …Model LE30755. LG does not sell the oven cavity as a replacement part

Does anyone have a suggestion as to where I might look for this part? Or where a second-hand part might be found?

Thank you,
McPhee

You may have to do quite a bit of local research to find it. LG appliances are sold by Home depot…you might start there. First check to see if your unit is still on warranty. A few appliance repair shops may also have used units. Just curious: Why do you need a cavity for yours?

I put tin foil on the bottom of the oven to catch cooking spills …a big mistake!!
The tin foil melted on to the oven and is actually fused with the enamel covering of the oven cavity. It can’t be scraped off without scraping off the enamel.
