Tried resetting the control board to defaults, checked for temp offset and added 25 degrees (this is the max) now it is off by 25 degrees. Checked what appears to be the temp probe and it is clean. I suppose the problem is in the control board. Any known problems of this type on this model?

If the difference is greater than 25 degrees, then the control board needs to be replaced. I've gone through a few service bulletins and don't see anything related to this problem. It's really not a common problem, you just got "lucky". I do show that this board was redesigned some time ago. No reason specified. The only difference that I see here is the price - used to be $144 (manufacturer suggested retail), now it's $221 (MSR). We sell the board for $196.95 and it will take about 2-3 weeks to get. Special order part with Bosch.

Since this is a microprocessor controlled appliance I guessed that the CPU may have become scrammbled, flipped the breaker off and waited a couple of minutes and powered it back up. Checked the temp and it is right on! Will keep an eye on it.
