Hello, i have a wall oven that doesn't maintain temp. The model number is 790.49693314. I was told it was the control board but looking on this site the pic that the repair guy sent me is the controller. doing my own research I've seen people say it could be a thermostat or the "control board" i see the site sells a "board" and a "controller"


Is there a way i can confirm before purchasing? as i would rather get more opinions.

Thank you
