After reading online about this apparent design flaw with the LG wall oven, I ordered the thermostat and a fuse (just in case). This was an extremely easy repair to do yourself. I am a woman but generally handy. It took me about 30-40 minutes, most of which was taking out and putting back all the screws holding the housing on the back of the oven. I used nothing more than a screw driving to do this repair. If I can do it....so can you.
