How to replace Oven Relay Control Board. Before we replaced the board, my wife tried to replace just the element. We had one we had ordered several years ago when this same thing happened. When that didn't work we replaced the board and could see where the old board was damaged so we figured this was the solution. It would have been except the bottom element my wife used to replace the old element (which was fine but had been thrown out figuring the new one was new so why keep the old one) was 1" shorter in the back than the old one. Unbeknownst to us, that one inch was very important as, some of the insulation had moved around and exposed metal that the back of the element was pushing up against. So as soon as we turned it one it was metal on metal and it burned the connectors right off. After a couple connectors blew off and we put our fingers back there and could feel the metal, we figured out what was going on and we were able to find a work around so there was no more metal on metal and the oven works great! So we had two issues, the original was the board was out and then our own made problem of to short of ends on the element. 108 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
