I have an WP OTR  Microwave/convection oven I mostly like.  Have an issue with the potato setting/option.  It is in no way correct.  I hadn't made a baked potato in a while and was doing a steak last night and popped a potato in.  Medium sized potato the oven sensed it then displayed  9 minutes!  Might have been longer that just when I noticed, potato was well done at that point.

I had a combo OTR oven from GE that I gave to a cousin and that oven turned out the best baked potatoes I've ever had from a microwave.  Just wondering if anyone knows if there is a way to recalibrate the sensor in the oven, or just forget it and guess at the time.
