Last week when trying to preheat the oven to cook a frozen pizza. I noticed the oven was taking a longer than usual time to reach temp. I also noticed a strange smell. I figured that the oven had a few food bits on the bottom. after a hour and the oven still wasn't at temp, I turned it off. I thought the bake element must have gone bad, so I ordered a replacement. Today after the replacement element arrived and taking off the back covered, I was horrified to discover that Range Oven Relay Control Board(LG EBR74164814) caught fire. I've only have had it a few years, and they only offer a 1 year warranty.
