Hi, my range's oven seems to not want to heat up much more than 145-200 degrees. It worked fine until yesterday. The exception being the fact that the convection fan died a couple of months ago. Does anyone think this could be a bad control board? I don't want to change the element or the thermostat if it's the board. I haven't gotten any error codes, and the unit has made some ticking noises since day one, which I assumed was normal. The front left burner on the cooktop, which is a dual element will only heat on the outer portion, and the control knob area has made popping noises prior to going out for over a year, so I don't know if any of this is related to the oven failure.

I have a replacement board, but don't want to replace it if it's not the cause. Any suggestions?
