I have a smaller size stove due to the amount of available space. No matter what temp I set it to it just keeps getting hotter and hotter. I set it to 350 and waited for it to heat up. When I went ot put my brownies in it seemed to hot so I used my thromometer and seen the temp was 425. I figured the thermostat was off so I reset the temp to 250 and when I checked again it was hotter still. no matter what I did the flame never shut down. Would this be the thermostat causig the problem ???
