First step to replace temperature sensor. It is accurate now and measures oven heating to set temperature, but climbing almost 40-50 degrees hotter than setting. Oven then falls back down to set temperature and elements come back on driving temps above setting almost 40-50 degrees original setting. If cooking something on hi-broil or 400+ degrees, after several minutes, the oven door locks because it thinks it is in cleaning mode. This temperature sensor was easy install. 1/4 driver and a clip in. Frustrating. Looking to replace motherboard next.
