Hello all, I have a KitchenAid double oven whose internal temperature for both the upper and lower ovens do not match up with what is displayed on the control panel. When the oven display says it is at 350, my oven thermometer says 250. It will eventually reach 350, but about 15 minutes after the oven thinks it is at the correct temperature, and it doesn’t do a good job maintaining the temperature. I have read that it is common for ovens to be slightly off since it takes a while for the entire oven to reach a constant temperature, but when trying the same test on my neighbor’s oven (a similar model), it is much closer once the oven says that it’s ready (only a 25 degree difference, and it only takes a couple of minutes to catch up). I know I am not imagining the problem because things are take almost twice as long to cook than they used to.
I have done some research regarding this problem, and from what I’ve read, the microcomputer (part #4448871) seems to be the defective part. I’m not certain though, as most people who discussed this problem referred to the defective part as a "control board". On the parts list I have, there’s a control panel, and a microcomputer. I am assuming the control panel doesn’t maintain the temperature, and that the control board is my case is the microcomputer.
Anyone have any ideas if I’m on the right track? Is there something else I can try before replacing this part?
