Okay, I replaced the thermostat and it is still not working. I checked the heating filaments and they work fine. I haven't replaced the sensor, but I'm assuming the oven would heat up even if the sensor was not working.
The fan kicks on and makes all of the noises like it is heating, the oven tells me it has heated up to 350 degrees, but there is no heat.
Any other suggestions? I was so excited to be able to fix this myself, but really have no idea what else may be wrong.
