F220 error on GE Stove JB860SJASS

[Todd Bjerregaard]

Made dinner the other night on the stove top and shortly after finishing, I got a F220 error on the display of my GE JB860SJASS. I unplugged it and took the kids to soccer practice and plugged back in when we got back. After about a minute the error came back. I looked online and it said it could be the temperature probes. I cleaned both of them even though I guess F220 is for the lower over, but this one is rarely used. Still came back with error. I checked the probes and the top one read 1096 Ohms and the lower read 1194? if I remember right. I read somewhere that they should read between 1080 and 1090. I tried running it with just the good probe in the bottom one and then got a F200 error so it thinks it is a single oven now. Regardless, I ended up just ordering 2 new temperature sensors and they came yesterday. Installed both of them and it still gives me the error. Next thing I saw was it could be a bad control board which is hard to diagnose and expensive to fix. This unit was just purchased on June 2, 2020, and the warranty expired a year later, so I would hate to have to buy a new stove or spend a lot fixing. Hoping someone can give me some advice as I've hit a wall looking online.
