Error Code F10

For the last 6 months we kept getting error code F10 now and again. I read up on this and did the following. Checked continuity at room temp of the oven heat probe. It was normal as per the specs that I saw. It was around 1100. I did the same on the wiring harness. Same result. So I went and bought and installed a new Control Board. Now it is doing it again within a week of board install. This range is about 3 years old and it is the second board replacement. First one went in the first 3 months. Should I replace the probe even though it shows that it is to spec? Any other ideas? Thanks
