I’m sure it’s probably a goner but who knows. Maybe there’s something that can be done? Have an LG (junk that was in the house when we bought it) microwave mounted above the stove. Recently it has started acting to certain foods like there is a piece of tinfoil in there. Canned green beans, just to warm up a serving looked like the 4th of July. I deep sixed that can thinking there must have been some metallic contaminant. Next Half a can was fine. Then it did it again...obviously it’s not contaminated. Now it’s burning the outer edges of Food but the middle is stone cold. Placement inside doesn’t make a difference. Thought I’d throw this one up in the air before I go drop a few hundo on a new nuking device. Any thoughts?
